Alkali-catalyzed liquefaction of pinewood sawdust in ethanol/water co-solvents was written by Hu, Yulin;Gu, Zicheng;Li, Wenbin;Xu, Chunbao. And the article was included in Biomass and Bioenergy in 2020.Name: 4-Hydroxy-3-methoxyphenethanol The following contents are mentioned in the article:
In this study, pinewood sawdust was liquefied in either ethanol/water co-solvents (50/50, weight/weight) or pure water at 300°C for 30 min and 10 wt% of feedstock loading, with or without the use of Na2CO3 or NaOH as a catalyst. The phys. and chem. properties of liquefaction products (bio-crude oil and solid residue) were comprehensively characterized by FT-IR, GC-MS, elemental, GPC and TGA analyses. The results showed that the highest biomass conversion of approx. 98% was obtained in ethanol/water mixed solvents and without catalyst, along with a maximum yield of bio-crude oil (∼48 wt%). The HHV of crude oil was within the range of 26-30 MJ/kg. The results indicated that the beneficial effect of ethanol on the bio-crude oil yield might be compromised by adding Na2CO3 or NaOH into the liquefaction system under investigated reaction conditions. As suggested by GPC anal., the bio-crude oil obtained in ethanol/water co-solvents from both non-catalytic and catalytic liquefaction contained a slightly higher mol. weight than that obtained in pure water. Addnl., TGA results indicated that the b.p. distribution of bio-crude oil was only affected by ethanol addition, whereas, the effect of the catalyst was found to be minor. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Name: 4-Hydroxy-3-methoxyphenethanol).
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. Esterification is the general name for a chemical reaction in which two reactants (typically an alcohol and an acid) form an ester as the reaction product. Esters are common in organic chemistry and biological materials.Name: 4-Hydroxy-3-methoxyphenethanol
