Abstract:
1. A process for the preparation of a purified partially esterified polyol fatty acid polyester composition comprising the steps of: a) forming an initial reaction mixture, said initial reaction mixture comprising: wherein the molar ratio of said polyol portion to said highly esterified polyol polyester is in the range of from about 0.1:1 to about 3:1, wherein the molar ratio of said catalyst to said highly esterified polyol polyester is in the range of from about 0.1:1 to about 40:1, and wherein the weight ratio of said solvent to the combined, weight of said polyol portion, said highly esterified polyol polyester, and said catalyst is in the range of from about 1:1 to about 20:1; forming as initial reaction product by reacting said initial reaction mixture in an inert atmosphere, in the presence of a sufficient amount of agitation, for a period of time in the range of from about 30 minutes to about 6 hours, and at a temperature in the range of from about 80° C. to about 140° C.; c) optionally drying said initial reaction product; wherein in Step (b) agitation is applied at a Weber Number in the range of from about 5000 to about 15000, and for a period of time in the range of from about 30 minutes to about 6 hours.
