    摘要： 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 C8-18 palm kernel oil fatty acid methyl ester; (b) fractionally distilling said C8-18 palm kernel oil fatty acid methyl ester to form a C8-14 head product and a C16-18 bottom product; (c) fractionally distilling the C16-18 bottom product to form a short-chain C16 head product and a long-chain and unsaturated C18 bottom product; (d) fractionally distilling the long-chain and unsaturated C18 bottom 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.

    摘要： 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.

    摘要： A process for the separation, by sedimentation, of at least one liquid organic component dispersed in a liquid containing mainly organic materials, this organic component and the remaining liquid exhibiting a difference in density. In order to reduce considerably the standing time, it is proposed that the liquid be passed before sedimentation through a fiber bed that the organic component and the remaining liquid have different surface tensions with respect to the fiber bed, that the temperature of the liquid and the concentration of the organic component to be separated are such that, in the equilibrium state, at least two liquid phases form, and that the rate of flow of the liquid through the fiber bed lies below a maximum value dependent on the surface tension of the organic component with respect of the fiber bed and on the difference in density and surface tension between the remaining liquid and the organic component.
