Abstract:
The present invention relates to a process for producing polyglyceryl ether derivatives in which the polyglyceryl ether derivatives are produced from an alcohol (except for glycidol and glycerol) and glycidol in the presence of an aluminosilicate which is ion-exchanged with at least one cation selected from the group consisting of ammonium ions, alkali metal ions and alkali earth metal ions. In the process of the present invention, a removal step of the catalyst can be simplified, and the polyglyceryl ether derivatives can be produced in an economical and efficient manner.
