Abstract
A process for the selective esterification of long chain length fatty acid monoglycerides, particularly monobehenin, with medium chain length fatty acids, particularly a mixture of C.sub.8 and C.sub.10 saturated fatty acids, 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 90% pure C.sub.6 -C.sub.10 fatty acid or mixture thereof at a temperature of from about 140.degree. to about 250.degree. C. in the substantial absence of an esterification catalyst. The mole ratio of fatty acid to monoglyceride used in this monoglyceride esterification is at least about 3:1. Water generated during this monoglyceride esterification is also continuously removed.
