  A process for producing wax ester comprising of esterifying dihydroxy fatty acid preferably dihydroxystearic acid with at least one alcohol in the presence of lipase as a catalyst which is then remove by filtration. The filtered catalyst could be reuse and provides a number of cost advantages. In the preferred embodiment of the present invention, the dihydroxystearic acid is derived from palm based oleic acid and the alcohol contains 8 to 18 carbon atoms per molecules.

  一种生产蜡酯的方法，包括在脂肪酶的催化下，将二羟基脂肪酸（最好是二羟基硬脂酸）与至少一种醇酯化，然后通过过滤去除催化剂。过滤后的催化剂可以重复使用，提供了多种成本优势。在本发明的首选实施例中，二羟基硬脂酸来自基于棕榈油的油酸，而醇含有每个分子8至18个碳原子。

  AbstractDihydroxystearic acid (DHSA) ester was synthesized enzymatically to overcome the problems associated with chemical processes. Immobilized enzyme, Lipozyme IM and Novozym 435, were employed as catalysts in the esterification reaction between DHSA and monohydric alcohol. Various factors that may affect the esterification reaction were studied, such as initial water content (aw), organic solvent, substrate concentration and the influence of alcohol chain length. It was found that the percent conversion was higher in organic solvents with log P (the logarithm of the partition coefficient of solvent in octanol/water system) from 2.0 to 4.0. The reaction was not affected by aw from 0.09 to 0.96. Increasing the mole ratio of alcohol to acid above 2.0 did not increase the percent converions of ester. The ester was identified by Fourier transform infrared and 13C nuclear magnetic resonance spectroscopy.
