PROCESS FOR PREPARING PURE MONOGLYCERIDES, PURE DIGLYCERIDES AND/OR TRIGLYCERIDES

摘要

The invention relates to a process for recovering monoglycerides and optionally diglycerides and/or triglycerides as well as optionally glycerol from mixtures comprising glycerides and glycerol containing glycerides, respectively, by countercurrent extraction with a circulating extraction, said process being characterized in that there is used as an extractant forming a separate phase a hydrocarbon having a density of more than 180 kg/m3 and/or trifluoromethane having a density of more than 180 kg/m3.
