Abstract
The present invention relates to the use of at least one sulfonic acid for recovering glycerol resulting from a reaction crude from transesterification of glycerides, in particular of triglycerides of vegetable and/or animal origin.The invention also relates to a process for purifying glycerol obtained as a by-product of triglyceride transesterification during the preparation of fatty acids, fatty esters and/or fatty acid salts, and also to a combined process for preparing, on the one hand, fatty acids, fatty esters and/or fatty acid salts and, on the other hand, glycerol, from triglycerides, using at least one sulfonic acid.
