PROCESS FOR PRODUCING SOLID PRODUCTS BY ESTERIFYING FREE FATTY ACIDS IN THE PRESENCE OF ACID CATALYSTS

摘要

P Process in which the fatty acids contained in the raw material are esterified in the presence of acidic catalysts with alcohols and the product mixture is then withdrawn. This process is characterized in that: (a) fats and oils are conducted with lower aliphatic alcohols on an acid catalyst bed of up to 60, BR/ b) separated water of reaction from the product of the first pre-esterification and the excess alcohol, BR/ c) the product of the first purified pre-esterification is conducted on an acid catalyst bed, while adding alcohol addition and the acid number is lowered to values from 0.1 to 0.9, and BR/ d) the second product of the pre-esterification is transesterified and / or hydrogenated. / P
