Process for removing double metal cyanide catalyst residues from a polyol |
| abstract |
The present invention relates to a process for removing double metal cyanide complex catalyst residue(s) from polyol(s) which comprises after polyol formation the steps of: (a) contacting the catalyst residue-containing polyol with an effective amount of an oxidant to cause said residue(s) to form insoluble residues that are insoluble in the polyol, and (b) separating the insoluble residues from the polyol. In another aspect, the present invention relates to the oxidant-free polyol produced by the above process. |
