ABSTRACT:
A process for the preparation of mono-fatty acid or hydroxymono-fatty acid esters of isopropylidene derivatives of a polyglycerol is disclosed. A C6-C22 fatty acid or -hydroxy fatty acid is reacted with isopropylideneglycerol glycidyl ether or diisopropylidenetriglycerol glycidyl ether in a molar ratio of 0.5:1 to 1:0.5 at temperatures of 373473 K. in the presence of a catalyst. The monoisopropylidenediglycerol mono-fatty acid ester or monoisopropylidenediglycerol hydroxy mono-fatty acid ester or diisopropylidenetetraglycerol mono-fatty acid ester or diisopropylidenetetraglycerol hydroxy mono-fatty acid ester obtained is optionally purified by distillation, fractional distillation and/or ion exchange.
