Abstract
Disclosed is a method for removing potassium from polyol and alkoxylated alkyl phenol products and neutralizing soluble base catalysts which comprises using a partially spent ion exchange resin which no longer meets the purity requirements for the production of MTBE, ETBE or TAME, washing the catalyst, mixing it with the polyol or alkoxylated alkylphenol in an acid/base ratio of about 7/1 to 10/1, for a period of hours and removing the filtrate.
Claims7
A method for removing potassium from polyol products which comprises using a partially spent insoluble cross-linked polymeric ion exchange resin catalyst possessing 60-90% of its original activity, washing the partially spent catalyst, mixing the polyol product with the partially spent catalyst in an acid/base ratio of 7/1 to 10/1, for a period of 1 to 5 hours and removing the filtrate.
