Ceria supported gold-platinum catalysts for the selective oxidation of alkyl ethoxylates was written by Heidkamp, Katharina;Aytemir, Memet;Vorlop, Klaus-Dieter;Pruesse, Ulf. And the article was included in Catalysis Science & Technology in 2013.Formula: C10H22O3 The following contents are mentioned in the article:

This work covers the development of a ceria based AuPt catalyst for the selective aerobic oxidation of alkyl ethoxylates to their corresponding carboxylic acids. By optimizing metal loading and the Au to Pt ratio the activity of the catalyst could be increased significantly, while maintaining total selectivity. Although the choice of ceria as a support helped to suppress intermediate metal leaching, the catalyst still showed poor long-term stability in repeated batches. The cause for deactivation could finally be identified by TPR studies as over-oxidation These suspicions were confirmed by a long-term stability study in continuous-mode. It proved to be possible to deactivate the catalyst on purpose by employing unfavorable oxidising reaction conditions, i.e. low substrate concentrations and excess oxygen. By avoiding such unfavorable conditions either in continuous-flow mode or in repeated batches, the long-term stability of the catalyst increased tremendously. A substrate screening of various ethoxylates showed that the catalyst was very well-suited to selectively oxidize a wide range of alkyl ethoxylates. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Formula: C10H22O3).

2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Formula: C10H22O3

An efficient and practical synthetic procedure for libraries of diversified 1,2-dihydrochromeno[2,3-c]pyrrole-3,9-diones I [R =H, 6,7-di-Me, 7-F, etc.; R¹ = n-Pr, CH₂CH₂OH, 2-furylmethyl, etc.; Ar = Ph, 4-MeC₆H₄, 3,4,5-tri-MeOC₆H₂, etc.] using a multicomponent process was presented. A convenient synthetic procedure for obtaining functionalized 3-(2-hydroxyphenyl)-4,5-dihydropyrrolo[3,4-c]pyrazol-6(1H)-ones II [R² = H, 3,5-di-Me, 4-Me-5-Cl, etc.; R³ = 4-BrC₆H₄, 2-OHC₆H₄, 3-MeO-4-OHC₆H₃, etc.; R⁴ = n-Pr, CH₂CH₂OH, 2-ClC₆H₄CH₂, etc.] via ring-opening strategy was developed. This protocol was found to be compatible with a wide range of substituents and paves the way for the practical synthesis of title compounds with a broad range of substituents under mild condition. The products could be easily isolated by crystallization without the use of chromatog. This study involved multiple reactions and reactants, such as 2-Methoxyethylamine (cas: 109-85-3Name: 2-Methoxyethylamine).

2-Methoxyethylamine (cas: 109-85-3) 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. 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.Name: 2-Methoxyethylamine

Properties and applications of microemulsions was written by Klier, John;Tucker, Christopher J.;Kalantar, Thomas H.;Green, D. P.. And the article was included in Advanced Materials (Weinheim, Germany) in 2000.Product Details of 112-59-4 The following contents are mentioned in the article:

Microemulsions are thermodynamically stable, fluid, optically clear dispersions of two immiscible liquids Recent interest in microemulsion systems has resulted from their utility in a broad range of applications including enhanced oil recovery, consumer and pharmaceutical formulations, nanoparticle synthesis, and chem. reaction media. However, the high levels typically required to ensure complete microemulsification and formulation stability often result in unacceptably high residue, contaminant levels, and formulation cost. One way to reduce surfactant requirements in microemulsion systems is through the use of efficient surfactants and interfacially active cosurfactants. The authors have explored and developed microemulsion systems based on efficient anionic surfactants and glycol ether cosurfactants that are stable to temperature and compositional changes and yet employ low levels of non-volatile surfactants. These microemulsion systems are finding utility in a range of applications, including consumer and industrial cleaning formulations, chem. reaction media, polymerization, and active ingredient delivery. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Product Details of 112-59-4).

2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Polyesters are important plastics, with monomers linked by ester moieties. Acyl chlorides and acid anhydrides alcoholysis is another way to produce esters. Acyl chlorides and acid anhydrides react with alcohols to produce esters. Anydrous conditions are recommended since both acyl chlorides and acid anhydrides react with water.Product Details of 112-59-4

Correlation and Prediction of Environmental Properties of Alcohol Ethoxylate Surfactants Using the UNIFAC Method was written by Cheng, Hongyuan;Kontogeorgis, Georgios M.;Stenby, Erling H.. And the article was included in Industrial & Engineering Chemistry Research in 2005.Recommanded Product: 112-59-4 The following contents are mentioned in the article:

Environmental properties of one type of nonionic surfactants, the alc. ethoxylates (polyoxyethylene alcs.), are predicted using the UNIFAC (universal quasi-chem. functional group activity coefficient) method. Various properties are considered; the octanol-water partition coefficient (K_ow), the bioconcentration factor (BCF), and the toxicity. K_ow values of alc. ethoxylates are difficult to measure. Existing methods such as those in com. software like ACD,¹³ ClogP,¹⁴ and KowWin¹⁵ have not been applied to surfactants, and they fail for heavy alc. ethoxylates (alkyl carbon numbers above 12). Thus, the K_ow values are predicted here via UNIFAC and compared to the few available exptl. data. Based on the predicted K_ow values, a correlation between K_ow and hydrophilic-lipophilic balance (HLB) is established because HLB is a widely used parameter in surfactant applications. Finally, BCF and toxicity of alc. ethoxylates are correlated with their K_ow. The proposed approach can be extended to other families of nonionic surfactants. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Recommanded Product: 112-59-4).

2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4) belongs to ethers. Carboxylic acid esters of low molecular weight are colourless, volatile liquids with pleasant odours, slightly soluble in water. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Recommanded Product: 112-59-4

Natural extracts have been used in several traditional medicine applications and culinary purposes. Their biol. properties (antioxidant and antimicrobial) are due to the presence of several active aromatic compounds Herein, different natural extracts were evaluated, namely structural and thermal characterization and biol. activity, in its natural form and incorporated into a polymeric matrix, to assess their effective potential as additives for active food packaging. While rosemary presented the highest thermal stability with a degradation starting at 327°C, lemon balm extract was the less stable (180°C). Regarding the thiobarbituric acid assay, all extracts presented antioxidant activity, in oxidative hemolysis inhibition; anise, cinnamon, and clove extract did not present any action. Overall, the results demonstrated that leaves (rosemary and green tea) and the rhizome (curcumin) are the plant parts with the best performance. Therefore, extracts from aromatic plants are promising natural additives that can be incorporated into polymeric matrixes to produce active food packaging film, increasing products shelf-life. This study involved multiple reactions and reactants, such as Bisdemethoxycurcumin (cas: 33171-05-0Formula: C19H16O4).

Bisdemethoxycurcumin (cas: 33171-05-0) belongs to ethers. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics.

Two cationic ruthenium(II) 1,4,7-trithiacyclononane ([9]aneS₃) complexes of curcumin (curcH) and bisdemethoxycurcumin (bdcurcH), namely [Ru(curc)(DMSO-S)([9]aneS₃)]Cl (1) and [Ru(bdcurc)(DMSO-S)([9]aneS₃)]Cl (2) were prepared from the [RuCl₂(DMSO-S)([9]-aneS₃)] precursor and structurally characterized, both in solution and in the solid state by x-ray crystallog. The corresponding PTA complexes [Ru(curc)(PTA)([9]aneS₃)]Cl (3) and [Ru(bdcurc)(PTA)([9]aneS₃)]Cl (4) were also synthesized and characterized (PTA = 1,3,5-triaza-7-phosphaadamantane). Bioinorganic studies relying on mass spectrometry were performed on complexes 1–4 to assess their interactions with the model protein lysozyme. Overall, a rather limited reactivity with lysozyme was highlighted accompanied by a modest cytotoxic potency against three representative cancer cell lines. The moderate pharmacol. activity is likely connected to the relatively high stability of these complexes.

In search of an efficient frother for pre-flotation of carbonaceous shale from the Kupferschiefer stratiform copper ore was written by Kowalczuk, Przemyslaw B.;Buluc, Batuhan;Sahbaz, Oktay;Drzymala, Jan. And the article was included in Physicochemical Problems of Mineral Processing in 2014.Synthetic Route of C10H22O3 The following contents are mentioned in the article:

Frothers such as aliphatic alcs. (C_nH_2n+1OH), poly(propylene glycols) (HO(C₃H₆O)_mH), poly(propylene glycol) alkyl ethers (C_nH_2n+1O(C₃H₆O)_mH) and poly(ethylene glycol) alkyl ethers (C_nH_2n+1O(C₂H₄O)_mH), can be used for collectorless flotation of a sample of carbonaceous Cu shale manually separated from the Kupferschiefer stratiform Cu ore. Flotation is influenced by the type and dose of frothers. The best flotation results were obtained with tri(propylene glycol) Bu ether C₄P₃, tri(propylene glycol) Pr ether C₃P₃ and tri(propylene glycol) P₃. For these frothers, the yield vs. frother dose relationship was in the form of convex curves indicating that carbonaceous Cu shale can float at relatively low dosages of the frother. These frothers can be used for pre-flotation of carbonaceous matter from the investigated Cu ore. Other frothers formed concave yield-frother dose relationships and were less effective. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Synthetic Route of C10H22O3).

Production of phenolic chemicals from hydrolysis lignin via catalytic fast pyrolysis was written by Paysepar, Hooman;Venkateswara Rao, Kasanneni Tirumala;Yuan, Zhongshun;Shui, Hengfu;Xu, Chunbao. And the article was included in Journal of Analytical and Applied Pyrolysis in 2020.Application In Synthesis of 4-Hydroxy-3-methoxyphenethanol The following contents are mentioned in the article:

Catalytic fast pyrolysis of hydrolysis lignin was investigated in a drop-tube fixed bed reactor at different temperatures ranging between 400-800°C using zeolite X as a catalyst for the production of phenolic chems. The yield of low mol. weight monomeric phenolics increased considerably while increasing the pyrolysis temperature from 400°C to 450°C, but decreased with further increasing the pyrolysis temperature Zeolite X remarkably increased the yield of monomeric phenolic compounds in the catalytic fast pyrolysis of hydrolysis lignin at all temperatures (400-800°C) compared to fast pyrolysis. No significant changes were observed in the catalyst properties (crystallinity and textural structure) during fast pyrolysis of lignin. The superb activity of the zeolite X catalyst might be owing to its strong acidity and low pore volume Under the best reaction conditions tested in this study (450°C, with zeolite X catalyst), the bio-oil yield was 50.5% in relation to the dry lignin, and the content of monomeric phenolics (mainly guaiacol, syringol, 4-methoxy-3-(methoxymethyl) phenol and metoxyeugenol) was 146.2 mg/g of bio-oil.

Selective catalytic hydrotreatment of lignin-derived phenols and dimeric ethers into alkanes is crucial for utilization of lignin and its fragments. Herein, we developed an efficient catalytic system with well-dispersed metal nanoparticles supported on SBA-15 synergistic with an ionic liquid The catalytic system could catalyze the hydrodeoxygenation (HDO) of various monomeric and dimeric lignin-derived phenols into the corresponding alkanes under acid free conditions. The synergistic [Bmim]PF₆-Ru/SBA-15 (1-butyl-3-methylimidazolium hexafluorophosphate) catalysis exhibited the best HDO activity for lignin-derived phenols and dimeric ethers with >99.0% conversion and maximum >98.0% selectivity of the corresponding alkanes. The yield of cyclohexane from di-Ph ether was 97.7% with 100% conversion under 2 MPa H₂ at 130 °C for 6 h. The mechanism investigation confirmed that the Ru/SBA-15 catalyst and the anion of [Bmim]PF₆ played crucial roles in the hydrogenation process and deoxidization process, resp. The catalytic system was reused six times for HDO of di-Ph ether to test its stability.
