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.
