Abstract

A PROCESS FOR REMOVING DOUBLE METAL CYANIDE COMPLEX CATALYST RESIDUES FROM A CATALYST- RESIDUE CONTAINING POLYOL CHARACTERIZED BY : (A) TREATING A DOUBLE METAL CYANIDE COMPLEX CATALYST- RESIDUE CONTAINING POLYOL WITH AN ALKALI METAL ALKOXIDE OR ALKALINE EARTH METAL ALKOXIDE IN ORDER TO PROVIDE A TREATED POLYOL WHEREIN SAID CATALYST- RESIDUE IS CONVERTED INTO INSOLUBLE IONIC INSOLUBLE SPECIES, (B)CONTACTING SAID TREATED POLYOL WITH ETHYLENE OXIDE TO PRODUCE AN ETHYLENE OXIDE- CAPPED POLYOL WHEREIN AT LEAST A PORTION OF THE SECONDARY HYDROXYL GROUPS ON SAID POLYOL ARE CONVERTED INTO PRIMARY HYDROXYL GROUPS, AND (C) SEPARATING SAID INSOLUBLE IONIC SPECIES FROM SAID ETHYLENE OXIDE- CAPPED POLYOL BY FILTRATION IN ORDER TO PROVIDE A PURIFIED POLYOL THAT IS ESSENTIALLY FREE OF CATALYST- RESIDUE. ALSO CLAIMED IS PROCESS FOR PREPARING A PURIFIED POLYOL THAT IS FREE OF ACID CATALYST RESIDUES.
