Abstract
The separation of free fatty acids from triglycerides and/or diglycerides is performed by an adsorptive chromatographic process in liquid phase with a crystalline aluminophosphate, e.g., AIPO.sub.4 -5, AIPO.sub.4 -11 or AIPO.sub.4 -54, as the adsorbent. A ketone, having from 3 to 8 carbon atoms, such as 2-heptanone, or a mixture thereof, alone or admixed with a normal alkane can be selected as the desorbent.
