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.

Method for producing technical oleic acid methyl esters

A process for making spherically-shaped sterol preparations involving: (a) providing a liquid sterol preparation; (b) forming the liquid sterol preparation into liquid sterol droplets; and (c) solidifying the liquid sterol droplets to form the spherically-shaped sterol preparations.

Spherical sterol preparations, their production and their use

The invention relates to a continuous process for the production of lower alkyl esters at temperatures of up to 100.degree. C. and under pressures of up to 10 bar by reaction of fatty acid triglycerides containing less than 1% free fatty acid with a lower alcohol in two stages in the presence of a homogeneous alkaline catalyst, the glycerol formed being removed after the first stage. To enable the process to be carried out with high yields and with lower maintenance, investment and energy costs than in the prior art, the reaction mixture is passed through a reactor and a following static separator only once in each stage, tube reactors are used as the reactors and the Reynolds number of the flow of the reaction mixture is greater than 2,300.
