PROCESS FOR CLARIFYING ALKOXYLATED ALCOHOLS

摘要

A process for clarifying an alkoxylated product mixture produced using a calcium-based catalyst wherein the product mixture is heated to a temperature of from about 80 DEG C. to about 175 DEG C. to produce a filtration feed, the filtration feed being passed through a filter medium comprising material possessing polar groups to produce a clarified filtrate, the filtration feed being passed through the filter medium within about 5 days of being prepared, the filtration feed being passed through the filter medium until the desired degree of clarification is obtained, the temperature of the clarified filtrate being less than about 30 DEG C. but above the pour point of the clarified filtrate.
