Document Type and Number:
WIPO Patent Application WO/2014/024717
Kind Code:
A1
Abstract:
[Problem] The purpose of the invention is to react pentaerythritol, trimethylolpropane, or another such polyhydric alcohol with a carbonic acid ester to obtain dipentaerythritol, ditrimethylolpropane, or another such polyhydric alcohol ether at a good yield.
[Solution] A method for producing a polyhydric alcohol ether characterized by the joint use of the following catalyst A and catalyst B when reacting a polyhydric alcohol and a carbonic acid ester and producing a polyhydric alcohol ether of a structure in which the polyhydric alcohol is dehydrated and condensed between molecules. Catalyst A: one or more compounds selected from the group consisting of compounds containing an alkali metal, compounds containing an alkaline earth metal, amines or salts thereof or complexes thereof, and semicarbazides or salts thereof. Catalyst B: one or more compounds selected from the group consisting of compounds containing boron, compounds containing titanium, and compounds containing zirconium.
