Process for removing glycerol from glycerides

摘要

Described is a process for removing glycerol and/or diglycerol from glycerides and glyceride mixtures by extraction, which process is characterized in that the glyceride or glyceride mixture is dissolved in organic compounds which preferably contain carbonyl and hydroxyl groups, if desired in combination with hydrocarbons, and that glycerol is extracted from the resulting solution with the aid of water. Thereby glycerol concentrations in the material to be purified of 0.1 weight % or lower may be obtained in a simple manner.
