Selective esterification of long chain fatty acid monoglycerides with medium chain fatty acids

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 C8 and C10 saturated fatty acids, is disclosed. In this process, an at least about 60% pure C18-C24 fatty acid monoglyc...

More Information
Summary: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 C8 and C10 saturated fatty acids, 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 90% pure C6-C10 fatty acid or mixture thereof at a temperature of from about 140 DEG to about 250 DEG 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.
