Method for treating methyl esters of higher fatty acids and device for carrying out this method

摘要

Methylesters of higher fatty acids are treated, so that an unreacted methanol is removed from unrefined methylesters after the second step of transesterification, the mixture is cooled, the precipitated heavier alkaline phase is separated and the lighter methylester phase is introduced into contact with water in the weight ratio methylesters : water from 1 : 0.01 to 1 : 0.40 and after its seating is dried.
