ABSTRACT:
Described is a process for the recovery of monoglycerides and diglycerides from a mixture containing monoglycerides, diglycerides and triglycerides by extraction with a supercritical extractant which comprises specific cosolvents. After the separation of the monoglycerides as bottom product in the separation column, the extract consisting of diglycerides and triglycerides is separated into diglycerides and triglycerides by fractionated pressure decrease and change of temperature in two consecutive regeneration columns. A portion of the product obtained in the first regeneration column is fed as reflux to the head of the separation column, and a portion of the product, obtained in the second regeneration column, is fed as reflux to the head of the first regeneration column for an improved separation.
