Abstract (en)
[origin: WO2020119839A1] Presented is a process for providing polyglycerol ester of fatty acids from a reaction mixture to which a metal catalyst is added, as well as a method for purifying an intermediate synthesis product containing excess fatty acid in addition to polyglycerol ester of fatty acids. Compared to the prior art, a significantly higher yield and a higher process rate are obtained while the feedstock, adjuvants, solvents and energy are used more economically.
