Abstract
The separation of free fatty acids from triglycerides is performed by an adsorptive chromatographic process in liquid phase with silica gel as the adsorbent. A ketone, having from 3 to 8 carbon atoms, such as 2-heptanone, an ester or an ether can be selected as the desorbent.
Claims14
A continuous, bulk process for separating free fatty acids and triglycerides from a feed mixture comprising free fatty acids and at least one triglyceride, said process comprising contacting said mixture at adsorption conditions with an adsorbent comprising silica gel having particle sizes from 35-60 mesh (U.S.) thereby selectively adsorbing said free fatty acids thereon, removing said triglyceride from contact with said adsorbent and desorbing said free fatty acids at desorption conditions with a desorbent comprising a liquid selected from the group consisting of lower ketones having from 3-8 carbon atoms, esters having up to about 8 carbon atoms and ethers having up to about 8 carbon atoms.
A continuous, bulk process for separating free fatty acids and triglycerides from a feed mixture comprising free fatty acids, diglycerides and at least one triglyceride, said process comprising contacting said mixture at adsorption conditions with an adsorbent comprising silica gel having particle sizes from 35-60 Mesh (U.S.), thereby selectively adsorbing said free fatty acids thereon, removing said triglyceride and a predetermined amount of said diglycerides from contact with said adsorbent and desorbing said free fatty acids and a second predetermined amount of said diglycerides at desorption conditions with a desorbent comprising a liquid selected from the group consisting of lower ketones having from 3-8 carbon atoms, esters having up to about 8 carbon atoms and ethers having up to about 8 carbon atoms.
