摘要： Glyceride-containing feed for a base catalyzed transesterification with lower alkanol to make biodiesel is pretreated with glycerin separated during the transesterification to partially convert glycerides with lower alkanol contained in the separated glycerin using base catalyst in the separated glycerin while reducing the free fatty acid and phosphorus compound concentrations in the glyceride-containing feed. Unique producer compositions are provided by the pretreatment processes.

摘要： The effluent from an acid esterification of free fatty acid with alkanol to produce alkyl ester of fatty acid is contacted with glycerin to remove water and alkanol. The alkanol separated with the glycerin can be recycled to the acid esterification by contacting the glycerin with fatty acid-containing feed being passed to the acid esterification.
