1. A process for the preparation of fatty acid esters of short-chain primary and secondary alcohols with 1 to 5 carbon atoms by transesterification of glycerides with such short-chain alcohols in the presence of transesterification catalysts at elevated temperatures, which comprises bringing the liquid glyceride into intimate contact with a stream of gaseous alcohol at temperatures of at least 210°

  • C., the throughput of this stream per unit time being at least such that it is capable of rapidly discharging the resulting product mixture of glycerol and fatty acid ester together out of the reaction zone, after which the product mixture is condensed and subjected to phase separation into a fatty acid ester phase and a glycerol phase and the excess gaseous alcohol is recycled to the reaction zone.
