ABSTRACT:
A method for pretreating crude oils and fats for subsequent alkaline transesterification with primary and/or secondary alcohols. The raw oil or fat loaded with slimy substances is treated with a mixture used at 0.15 wt. % in relation to the oil or fat comprising an alcohol and concentrated acid, and preferably is subsequently rinsed with an alkaline glycerol phase arising from an alkaline transesterification reaction of the above-mentioned type. After the rinsing process, the glycerol phase which is loaded with slimy substances and soaps of free fatty acids is separated as a heavy phase of neutral oil liberated from free fatty acids.
