PREPARATION OF POLYGLYCEROLS

摘要

The invention relates to a method for preparing polyglycerol, comprising - providing a catalyst salt on a support, the catalyst salt having catalytic activity with respect to an etherification reaction of a polyol selected from the group of glycerol and oligoglycerols, - contacting the catalyst salt on the support with a fluid phase comprising a polyol selected from the group of glycerol and oligoglycerols, - and subjecting the polyol in the fluid phase to an etherification reaction in the presence of the catalyst salt, thereby forming the polyglycerol.
