Abstract:
A process for the purification of crude polyether polyols is provided, wherein the crude polyether polyols are prepared by anionic polymerization of alkylene oxides in the presence of basic catalysts, the process comprising the steps of: neutralization of the catalysts with mineral acid, addition of adsorption agents and/or filter agents and removing the resultant salts and added filter aids by filtration wherein a filter cake is formed, and wherein polyether polyols are recuperated from the filter cake in a subsequent step of pressing the filter cake.

Claim (Index 12):
The process of  claim 11 , wherein the recuperated polyether polyol of the last batch of a production cycle is stored and blended with filtered polyether polyol of the first batch of a subsequent production cycle.
