| 摘要 |
The present invention concerns the use of at least one sulphonic acid for recovering glycerol from a reaction crude for the transesterification of glycerides, in particular triglycerides of plant and/or animal origin. The invention also concerns a method for purifying the glycerol obtained as a by-product of triglyceride transesterification during the preparation of fatty acids, fatty esters and/or fatty acid salts, and a combined method for preparing fatty acids, fatty esters and/or fatty acid salts, and glycerol, from triglycerides, implementing at least one sulphonic acid. |
