Claims20
A process for preparing specific complete mixed polyol esters from [unsymmetrically substituted] partial polyol esters with substantially no ester group rearrangement comprising esterifying [said] a partial polyol [esters] ester with an acid anhydride in the presence of a catalytic amount of a member selected from the group consisting of perfluoroalkyl sulfonic acids and perfluoroalkyl sulfonic acid anhydrides , said partial polyol ester being selected from the group consisting of partial polyol esters from aliphatic diols having the hydroxyl groups unsymmetrically substituted with respect to the carbon chain and partial polyol esters from aliphatic polyols containing at least three hydroxyl groups.
A process for preparing a synthetic cocoa butter comprising acylating the 2-hydroxyl group of 1-palmitoyl-3-stearoyl glycerol with oleic anhydride in the presence of a catalyst selected from the group consisting of perfluoroalkyl sulfonic acids and perfluoroalkyl sulfonic acid anhydrides, and crystallizing and separating the synthetic cocoa butter thus formed.
A process for preparing synthetic cocoa butter comprising:
- (1) admixing substantially completely hydrogenated palm oil with glycerol in the presence of triacetin and sodium methoxide catalyst;
- (2) separating and crystallizing the 1,3-diglycerides formed;
- (3) acylating the 2-hydroxyl groups thereof with oleic anhydride in the presence of a catalyst selected from the group consisting of perfluoroalkyl sulfonic acids and perfluoroalkyl sulfonic acid anhydrides;
- and (4) crystallizing and separating the synthetic cocoa butter thus formed.
