Comparative study of the fast pyrolysis behavior of ginkgo, poplar, and wheat straw lignin at different temperatures was written by Wang, Lei;Zhang, Ran;Li, Jian;Guo, Li;Yang, Haiping;Ma, Fuying;Yu, Hongbo. And the article was included in Industrial Crops and Products in 2018.SDS of cas: 2380-78-1 The following contents are mentioned in the article:

Fast pyrolysis of milled wood lignin (MWL) isolated from ginkgo (soft wood), wheat straw (herbaceous biomass), and poplar (hardwood) were conducted at various temperatures (400/600/800 °C) and the liquid products were analyzed by GC-MS. Then all MWLs were fully characterized using GPC, TGA, FT-IR, 2D NMR, and elemental analyzes. Ginkgo MWL showed higher selectivity toward guaiacols (92.38%) at low temperature (400 °C), especially a higher selectivity for five useful compounds (67.7%), namely creosol (10.24%), 2-methoxy-4-vinylphenol (17.83%), vanillin (15.65%), isoeugenol (14.84%), and apocynin (9.14%), as compared to MWLs from wheat straw or poplar. Overall, ginkgo lignin exhibits vast potential for volatilization at low temperature-selective pyrolysis, because it retains highly concentrated guaiacol-type structures which are easy to deconstruct and a few β-5′ phenylcoumarans that are hard to crack. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1SDS of cas: 2380-78-1).

4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) belongs to ethers. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Liquid esters of low volatility serve as softening agents for resins and plastics. Esters also include many industrially important polymers. Polymethyl methacrylate is a glass substitute sold under the names Lucite and Plexiglas; polyethylene terephthalate is used as a film (Mylar) and as textile fibres sold as Terylene, Fortrel, and Dacron.SDS of cas: 2380-78-1

Hydrothermal conversion of biomass (Xanthium strumarium) to energetic materials and comparison with other thermochemical methods was written by Durak, Halil;Genel, Yasar. And the article was included in Journal of Supercritical Fluids in 2018.Synthetic Route of C9H12O3 The following contents are mentioned in the article:

In the present study, the biomass was converted into liquid and solid residues by using hydrothermal liquefaction method at 250, 300 and 350°C with (FeCl₃, NaOH) and without catalyst. The resultant products were examined using GC-MS, FT-IR, ¹H NMR, SEM, and elemental anal. methods. According to the performed analyses, the highest liquid product yield (total bio-oil) was found to be 38.08% at 300°C by using FeCl₃ as catalyst. In the experiments carried out at 350°C, the highest HHV value was found to be 32.35 MJ kg^-1 by using NaOH catalyst. The energy values of products obtained at the end of experiments were compared to the values obtained from pyrolysis and supercritical liquefaction method, and it was determined that the liquid products having higher level of energy value were achieved by using hydrothermal liquefaction method. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Synthetic Route of C9H12O3).

4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Synthetic Route of C9H12O3

Effect of different extraction agents on enrichment of active components from wood vinegar was written by Lu, Xincheng;Jiang, Jianchun;He, Jing;Sun, Kang;Sun, Yunjuan. And the article was included in Linchan Huaxue Yu Gongye in 2020.Product Details of 2380-78-1 The following contents are mentioned in the article:

The enrichment effect of different extraction agents on active components of wood vinegar from waste fir plate was studied. The results showed that different extraction agents exhibited different effects on the enrichment of active components in wood vinegar. Et acetate, chloroform and ether exhibited good enrichment effect on phenolic substances, which ether present better extraction performance; Et acetate and chloroform had good enrichment effect on ketones. Three extractants had no obviously enrichment effect on esters, aldehydes and alcs., and they were not conducive to the enrichment of acid substances. Methanol addition was contributed to increase the enrichment effect of ether on phenolic substances. When the volume ratio of ether to methanol was 2:1, GC content of phenolic compounds reached to 66%, which was 1.96 times that of un-treated wood vinegar. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Product Details of 2380-78-1).

Pre-almond supplemental forage improves colony survival and alters queen pheromone signaling in overwintering honey bee colonies was written by Carroll, Mark J.;Meikle, William G.;McFrederick, Quinn S.;Rothman, Jason A.;Brown, Nicholas;Weiss, Milagra;Ruetz, Zachary;Chang, Erica. And the article was included in Apidologie in 2018.Computed Properties of C9H12O3 The following contents are mentioned in the article:

Supplemental forage can be used to provide nutrition to bees during winter dearth. We examined the effects of supplemental forage on colony performance, colony survival, worker quality, and queen pheromone signaling in Nosema ceranae-infected overwintering colonies. Colonies were either supplemented with rapini or left unsupplemented for 1 mo before almond pollination. Unsupplemented colonies experienced higher mortality than supplemented colonies. Supplemental forage did not affect colony performance, worker mass, or hypopharyngeal gland protein content. However, supplemented queens released more of three queen QMP and QRP compounds (4-hydroxy-3-methoxyphenylethanol, Me oleate, and 1-hexadecanol) that promote queen care among workers. In addition, colonies that survived almond pollination thermoregulated their hives more than colonies that failed. Supplemental forage may prepare overwintering colonies for the stresses of early spring pollination.

In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Computed Properties of C9H12O3

Sensory descriptive and comprehensive GC-MS as suitable tools to characterize the effects of alternative winemaking procedures on wine aroma. Part I: BRS Carmem and BRS Violeta was written by de Castilhos, Mauricio Bonatto Machado;Del Bianchi, Vanildo Luiz;Gomez-Alonso, Sergio;Garcia-Romero, Esteban;Hermosin-Gutierrez, Isidro. And the article was included in Food Chemistry in 2019.HPLC of Formula: 2380-78-1 The following contents are mentioned in the article:

This study analyzed the volatile composition and aroma profile of BRS Carmem and BRS Violeta red wines elaborated from traditional and two alternative winemaking procedures: grape pre-drying and submerged cap. The wines contained higher concentration of acetates (ranging from 303 mg L^-1 to 905 mg L^-1) and Et and Me esters (ranging from 138 mg L^-1 to 415 mg L^-1). The BRS Carmem wines were described as fruity due to the higher concentration of esters and BRS Violeta wines were described as vegetal mainly due to the higher concentration of terpenes and methoxyphenols. C6 alcs. also influenced the vegetal notes of BRS Violeta wines from traditional and submerged cap procedures and the pre-dried wines also presented a relevant jam note possibly due to the presence of 2-phenylethyl acetate. The changes in winemaking procedures can possibly lead to changes in the aromatic profile of red wines in a pos. way, improving the wine aroma quality. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1HPLC of Formula: 2380-78-1).

Isolation and Purification of Monofunctional Methoxyphenols from Loblolly Pine Biocrude was written by Mante, Ofei. D.;Thompson, Samuel J.;Soukri, Mustapha;Dayton, David C.. And the article was included in ACS Sustainable Chemistry & Engineering in 2019.Product Details of 2380-78-1 The following contents are mentioned in the article:

Methoxyphenols (MPs) are valuable chems. in liquid intermediates from pyrolysis of lignocellulosic biomass. The use of a single technique to recover a high-purity bioproduct of MPs from pyrolysis liquid is challenging. The purpose of this study is to combine distillation and chromatog. techniques in sequence to recover exclusively eugenols and guaiacols as monofunctional MPs in biocrude produced from the pyrolysis of loblolly pine with a nonzeolite alumina catalyst. A biocrude containing 11.0 wt % of the targeted monofunctional MPs was first distilled in two stages to recover an MP-rich fraction with 49.3 weight % concentration of MPs at a recovery efficiency of 86.9%. A chromatog. separation using silica gel adsorbent was then used to purify the MP-enriched distillate. A final MP bioproduct with average purity of 87.3-93.1 weight % was achieved. The average efficiency of the chromatog. separation step varied between 73.9 and 82.5% depending on the silica particle size used. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Product Details of 2380-78-1).

Kraft lignin depolymerization in sub- and supercritical water using ultrafast continuous reactors. Optimization and reaction kinetics was written by Abad-Fernandez, Nerea;Perez, Eduardo;Martin, Angel;Cocero, Maria J.. And the article was included in Journal of Supercritical Fluids in 2020.Quality Control of 4-Hydroxy-3-methoxyphenethanol The following contents are mentioned in the article:

Kraft lignin was rapidly depolymerised in a continuous reactor using sub- and supercritical water. The reaction yielded an aromatic oil rich in high value aromatic monomers such as guaiacol, vanillin, acetovanillone and homovanillic acid. Different temperatures between 300 and 400°C and reaction times from 60 ms were studied. An increment in reaction time at every temperature studied promoted secondary reactions of repolymn. of the lignin products. Those undesired reactions were more relevant as temperature increased. An optimal temperature of 386°C at a reaction time of 170 ms was found, with a maximum yield in phenolic compounds obtained. At those conditions, a bio-oil containing low mol. weight compounds was obtained with a yield of 44.6%. A selectivity to the four cited monomers of 9.9% was achieved, with little formation of solid residue (3.5%). A simple kinetic model was proposed to describe the yield for the different fractions and fitted to exptl. data. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Quality Control of 4-Hydroxy-3-methoxyphenethanol).

4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) belongs to ethers. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Quality Control of 4-Hydroxy-3-methoxyphenethanol

Comparative study of wet and dry torrefaction of corn stalk and the effect on biomass pyrolysis polygeneration was written by Wang, Xianhua;Wu, Jing;Chen, Yingquan;Pattiya, Adisak;Yang, Haiping;Chen, Hanping. And the article was included in Bioresource Technology in 2018.Synthetic Route of C9H12O3 The following contents are mentioned in the article:

Wet torrefaction (WT) possesses some advantages over dry torrefaction (DT). In this study, a comparative anal. of torrefied corn stalk from WT and DT was conducted along with an investigation of their pyrolysis properties under optimal conditions for biomass pyrolysis polygeneration. Compared with DT, WT removed 98% of the ash and retained twice the amount of hydrogen. The impacts of DT and WT on the biomass macromol. structure was also found to be different using two-dimensional perturbation correlation IR spectroscopy (2D-PCIS). WT preserved the active hydroxyl groups and rearranged the macromol. structure to allow cellulose to be more ordered, while DT removed these active hydroxyl groups and formed inter-crosslinking structures in macromols. Correspondingly, the bio-char yield after WT was lower than DT but the bio-char quality was upgraded due to high ash removal. Furthermore, higher bio-oil yield, higher sugar content, and higher H₂ generation, were obtained after WT. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Synthetic Route of C9H12O3).

4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) belongs to ethers. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics.

Relating sensory analysis with SPME-GC-MS data for Spanish-style green table olive aroma profiling was written by Lopez-Lopez, Antonio;Sanchez, Antonio Higinio;Cortes-Delgado, Amparo;de Castro, Antonio;Montano, Alfredo. And the article was included in LWT–Food Science and Technology in 2018.Application In Synthesis of 4-Hydroxy-3-methoxyphenethanol The following contents are mentioned in the article:

The sensory profile and volatile composition of 24 samples of Spanish-style green table olives were studied by Quant. Descriptive Anal. and solid phase micro-extraction gas chromatog. coupled to mass spectrometry (SPME-GC-MS), resp., with the aim to characterize this type of table olive. The aroma of samples was described by the sensory panel using nine descriptors (lactic, green fruit, ripe fruit, grass, hay, musty, lupin, wine, and alc.). A total of 133 volatile compounds were identified in the headspace of samples. Principal component anal. (PCA) applied to both datasets showed a poor separation of samples according to cultivars, but a trend to sep. according to sampling time. Reliable partial least squares (PLS) regression models were developed for four sensory descriptors (lactic, lupin, wine, and alc.) and allowed identifying the compounds both pos. and neg. correlated to such odor sensations. Such models could be used to predict the intensity of the above-mentioned descriptors as a function of SPME-GC-MS data.

Enzymatic hydrolysis of corn stover lignin by laccase, lignin peroxidase, and manganese peroxidase was written by Zhang, Sitong;Dong, Zijian;Shi, Jia;Yang, Chengrui;Fang, Yi;Chen, Guang;Chen, Huan;Tian, Chunjie. And the article was included in Bioresource Technology in 2022.Formula: C9H12O3 The following contents are mentioned in the article:

Lignin of high purity and structural integrity was isolated from the enzymic residue of corn stover. Degradation of the lignin by laccase, lignin peroxidase, and manganese peroxidase was investigated. Structural changes in the lignin after degradation were characterized by SEM, nitrogen adsorption and Fourier transform IR spectroscopy, and the enzymic products were systematically analyzed by gas chromatog. mass spectrometry. The highest percentage of lignin degradation was obtained with a mixture of three enzymes (25.79%): laccase (Lac), the starting enzyme of the mixed enzyme reaction, worked with lignin peroxidase (LiP), and manganese peroxidase (MnP) to further degrade lignin. This degradation destroyed the macromol. structure of lignin, broke its key chem. bonds, and opened benzene rings, thus producing more acidic compounds This study elucidated the concept of degrading lignin from corn stover using the Lac, LiP and MnP enzymes synergistically, thus providing a theor. basis for the biodegradation of lignin. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Formula: C9H12O3).

4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) belongs to ethers.
