Preparation of Propylene Glycol Fatty Acid Ester or Other Glycol or Polyol Fatty Acid Esters

A method for the preparation of a polyol fatty acid ester utilizes a combination of methyl soyate and a polyol in a molar ratio of approximately 2:1 in the presence of a basic catalyst to produce a fatty acid ester. Methanol is removed during a distillation process to drive the reaction process. Opt...

More Information
Summary:A method for the preparation of a polyol fatty acid ester utilizes a combination of methyl soyate and a polyol in a molar ratio of approximately 2:1 in the presence of a basic catalyst to produce a fatty acid ester. Methanol is removed during a distillation process to drive the reaction process. Optionally, gas sparging can be utilized to aide in methanol recovery. In one embodiment, the method is employed to produce a propylene glycol disoyate product that does not require further purification or distillation to remove a relatively high boiling methyl soyate reactant.
