Synthesis of alkyl succinates from Succinic Acid Fermentation Broths

摘要

PURPOSE: A method for preparing alkyl succinate from succinic acid fermentation liquid is provided to obtain alkyl succinate with excellent oil solubility. CONSTITUTION: A method for preparing alkyl succinate of chemical formula 1 comprises: a step of fermenting glucose, ligneous system, seaweed, or a mixture thereof to obtain succinic acid fermentation liquid; and a step of performing aqueous esterification of the succinic acid fermentation liquid and fat alcohol under the presence of an enzyme catalyst. The fat alcohol is prepared from plant-derived fatty acid methyl ester. The fatty acid methyl ester is isolated from corn oil, cotton seed oil, linseed oil, peanut oil, soybean oil, sunflower oil, palm oil, or coconut oil. The enzyme is Candida antarctic lipase(CAL), mutated Candida antarctic lipase(CALB), or Pseudomonas species lipase(PSL).
