Choice esterification null of long-chain fatty acid mono glyceride with medium chain fatty acid

摘要

A process for the selective esterification of long chain length fatty acid monoglycerides, particularly monobehenin, with medium chain length fatty acid anhydrides, particularly a mixture of C8 and C10 saturated fatty acid anhydrides is disclosed. In this process, an at least about 60 % pure C18-C24 fatty acid monoglyceride or mixture thereof is esterified with an at least about 50 % pure C6-C10 fatty acid anhydride or mixture thereof at a temperature of from about 90 ° to about 190 °C in the substantial absence of an esterification catalyst. The mole ratio of fatty acid anhydride to monoglyceride used in this monoglyceride esterification is at least about 2:1.
