Abstract
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 C.sub.8 and C.sub.10 saturated fatty acid anhdyrides is disclosed. In this process, an at least about 60% pure C.sub.18 -C.sub.24 fatty acid monoglyceride or mixture thereof is esterified with an at least about 50% pure C.sub.6 -C.sub.10 fatty acid anhydride or mixture thereof at a temperature of from about 90.degree. to aobut 190.degree. 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.
