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: b) forming an 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) adding a secondary reaction mixture, said secondary reaction mixture comprising a second polyol portion, wherein, following the addition of said secondary reaction mixture, the molar ratio of the combination of said first polyol portion and said second polyol portion to said highly esterified polyol polyester is in the range of from about 1:1 to about 40:1; d) forming a secondary reaction product by reacting said initial reaction product and said secondary 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 4 hours, and at a temperature in the range of from about 80° C. to about 140° C.; and, e) neutralizing the catalyst in the secondary reaction product with acid; f) optionally drying said secondary reaction product comprising said purified partially esterified polyol fatty acid polyester compositions; wherein in Step (b) agitation is applied at a Weber Number in the range of from about 5000 to about 15000, and wherein in Step (d) agitation in applied at a Weber Number in the range of from about 5000 to about 15000.
