Process for the manufacture of a polyether polyol by reaction between an organic compound containing 2 or more active hydrogen atoms in the molecule and an alkylene oxide in the presence of a catalyst comprising a tertiary amine NRR'.sub.2, in which R is a cycloalkyl or cycloalkenyl group and each R' may be an alkyl, cycloalkyl or cycloalkenyl group.

Polyether polyol process

A process for the preparation of polyethers by reaction between a polyol reactant having a melting point above 80.degree. C. and alkylene oxide, during which a substantially continuous flow of alkylene oxide is passed through a bed of the polyol. The polyether products find particular application, for instance, in the manufacture of polyurethanes.
