WebJun 2, 2014 · Of all the three ionic liquids, choline hydroxide was found to give the best results in terms of yield, efficiency, and recyclability. After studying various reaction parameters, 4 wt% catalyst dosage at a temperature of 60°C was optimized to give the best results when the ratio of methanol to soybean oil was 9 : 1 (see Scheme 15). WebNov 12, 2024 · The synthesis of YBa2Cu3O7−x (YBCO or 123) was carried out via the use of a variety of deep eutectic solvents (DESs), all formed by the interaction of choline hydroxide (as the cation source) and alkyl carboxylic acids with CnH2n+1 ranging from n = 2 to n = 10, namely acetic acid, propionic acid, butyric acid, pentanoic acid, nonanoic … h8fh-ic-d-20
Synthesis of choline chloride by self-catalyzed reaction
WebTake choline-based AAILs as an example, they are synthesized by choline hydroxide and amino acid [22]. They are well known to be nontoxic and biodegradable, and have been applied well in the pre-treatment of biomass. However, one of raw materials of choline-based AAILs, choline hydroxide is unstable and expensive. WebJun 3, 2024 · Choline hydroxide (ChOH) catalyst exhibited better catalytic activity compared with other basic ionic liquid catalysts, and methanol is the best alcohol for biodiesel synthesis. WebThis article describes a facile one-pot synthesis of bio diesei from non-treated Jatropha oil {J oil) with high acid value (ca. 17 mg KOH/g). Choline hydroxide exhibited superior catalytic activity than choline imi dazole in the transesterification that yields 95 ± 1% of biodiesel, when the reaction was carried out with 9 : 1 bradford broadway zone manager
