Abstract:
A continuous, solvent free process for preparing polyol fatty acid polyesters by interesterifying polyol containing more than about four esterifiable hydroxy groups and fatty acid ester wherein(1) the initial catalyst level is from about 0.001 to about 0.5 mole of catalyst per mole of polyol;(2) the polyol is a particulate solid having a particle size of less than 100 microns and when the degree of esterification of the polyol has reached about 15% but is no more than 75%, substantially all unreacted polyol particles are removed or substantially completely reacted; and(3) the initial stages of the reaction are carried out under conditions which maintain a level of lower partial fatty acid esters of said polyol in an emulsifying amount.
