SELECTIVE ESTERIFICATION OF LONG CHAIN FATTY ACID MONOGLYCERIDES WITH MEDIUM CHAIN FATTY ACID ANHYDRIDES

A process for the selective esterification of long chain length fatty acid monoglycerides, particularly monobehenin, with medium chain length fatty acid anhdyrides, particularly a mixture of C8 and C10 saturated fatty acid anhdyrides is disclosed. In this process, an at least about 60% pure C18-C24...

Zusammenfassung:	A process for the selective esterification of long chain length fatty acid monoglycerides, particularly monobehenin, with medium chain length fatty acid anhdyrides, particularly a mixture of C8 and C10 saturated fatty acid anhdyrides 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 DEG to aobut 190 DEG C. in the substantial absence of an esterificastion catalyst. The mole ratio of fatty acid anhydride to monoglyceride used in this monoglyceride esterification is at least about 2:1.
