PROCESS FOR PREPARING POLYETHER CARBONATE ALCOHOLS

A process for preparing polyether carbonate alcohols by attaching cyclic propylene carbonate to an H-functional starter substance in the presence of a catalyst, characterized in that at least one compound according to formula MnX (I) is used as a catalyst, wherein M is selected from the alkali metal...

Beschreibung
Zusammenfassung:	A process for preparing polyether carbonate alcohols by attaching cyclic propylene carbonate to an H-functional starter substance in the presence of a catalyst, characterized in that at least one compound according to formula MnX (I) is used as a catalyst, wherein M is selected from the alkali metal cations Li+, Na+, K+ and Cs+, X is selected from the anions VO3−, WO42−, MoO42− and VO43−, n is 1, if X═VO3−, n is 2, if X═WO42− or MoO42−, and n is 3, if X═VO43−.
