Claims19
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 hydrogen bromide source[.] , said partial polyol ester being 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 polyol containing at least three hydroxyl groups.
A process for preparing a synthetic cocoa butter comprising acylating the 2-hydroxy group of 1-palmitoyl-3-stearoyl glycerol with oleic anhydride in the presence of a catalyst selected from the group consisting of hydrogen bromide and hydrogen bromide sources, and crystallizing and separating the synthetic cocoa butter thus formed.
A process for preparing a confectioner's hard butter comprising acylating the 2-hydroxy groups in a mixture comprising 1-palmitoyl-3-stearoyl glycerol, 1,3-distearoyl glycerol and 1,3-dipalmitoyl glycerol with oleic anhydride in the presence of a catalytic amount of hydrogen bromide.
A process for preparing a confectioner's hard butter comprising:
- (1) admixing substantially completely hydrogenated palm oil with glycerol in the presence of a sodium methoxide catalyst and separating and crystallizing the 1,3-diglycerides formed;
- (2) acylating the 2-hydroxy groups of the 1,3-diglycerides prepared in step (1) with oleic anhydride in the presence of a catalyst selected from the group consisting of hydrogen bromide and hydrogen bromide sources;
- and (3) crystallizing and separating the hard butter thus formed.
