    • A chemoenzymatic process for the production of fatty acid esters comprising partially esterifying one or more fatty acid esters, under mild temperatures with an enzymatic catalyst, and optionally in the presence of one or more inert solvents, with a 1- to 5-fold molar excess of one or more water-containing aliphatic alcohols with boiling points between 60° C. and 120° C., then removing the water and unreacted alcohol(s) from the resulting pre-esterification product, followed by additional esterification up to 99.7%, chemically-catalyzed with, e.g., an acid or tin salt at slightly higher temperatures, optionally using one or more inert solvents, with a 1- to 4-fold molar excess of the same one or more aliphatic alcohols as employed in the preliminary esterification step.
    • 一种用于生产脂肪酸酯的化学酶法,其包括在温和的温度下用酶促催化剂部分酯化一种或多种脂肪酸酯,并且任选地在一种或多种惰性溶剂的存在下,以1〜5倍摩尔过量 的一种或多种沸点为60℃至120℃的含水脂族醇,然后从所得预酯化产物中除去水和未反应的醇,然后进一步酯化达99.7%, 用稍高的温度下的酸或锡盐进行化学催化,任选地使用一种或多种惰性溶剂,与初步酯化步骤中使用的相同的一种或多种脂肪醇的1至4倍摩尔过量 。
