Abstract
A process for making technical oleic acid methyl esters having a stearic acid methyl ester content of less than about 2% by weight, and a palmitic acid methyl ester content of less than about 5%, comprising: (a) providing a Cpalm kernel oil fatty acid methyl ester; (b) fractionally distilling said Cpalm kernel oil fatty acid methyl ester to form a Chead product and a Cbottom product; (c) fractionally distilling the Cbottom product to form a short-chain Chead product and a long-chain and unsaturated Cbottom product; (d) fractionally distilling the long-chain and unsaturated Cbottom product to form a predominantly unsaturated head product having a high palmitic acid methyl ester content and a predominantly unsaturated bottom product have a minimal palmitic acid methyl ester content; and (e) fractionally distilling the predominantly unsaturated bottom product have a minimal palmitic acid methyl ester content to form a head product rich in oleic acid methyl ester and poor in stearic acid methyl ester and a bottom product rich in both oleic acid methyl ester and stearic acid methyl ester.
