Phase transfer catalyst for use in the synthesis of polyol fatty acid polyesters

Abstract From the Canadian patent

A reaction mixture for manufacturing polyol fatty acid polyesters comprises a polyol, a fatty acid lower alkyl ester a base initiator and a phase transfer catalyst. The phase transfer catalyst can be a quaternary ammonium compound a , crown ether, a polyethylene glycol a polyethylene glycol ether, a , polyethylene glycol ester or mixtures thereof. The process of making polyol fatty acid polyesters is carried out at low temperatures and essentially in the absence of a solvent or emulsifier. The polyol fatty acid polyester product stream produced by the foregoing process and reaction mixture has a lower concentration of reaction by-products such as di-fatty ketones and betaketoesters …
