PROCESS FOR PREPARING LOW UNSATURATION POLYETHER POLYOLS |
摘要 |
Polyether polyols having reduced terminal unsaturation are prepared in a process comprising a first step of contacting a polyether having allyl terminal unsaturation with an isomerization catalyst whereby the allyl terminal unsaturation of the polyether is reduced by conversion to propenyl terminal unsaturation and, in a final step, the resulting polyether product of the first step is contacted with an acid catalyst whereby a substantial amount of the propenyl terminal unsaturation of the polyether is removed and the corresponding polyether having an additional hydroxyl group is obtained. |
