METHOD OF SEPARATING A CYCLIC ALKANE DIOL OR POLYOL FROM A LINEAR FORM OF SAID DIOL OR POLYOL

摘要

The invention relates to a method of separating a cyclic alkanediol or polyol from the linear form of the diol or polyol. The method comprises contacting a composition containing the cyclic alkanediol or polyol and the linear form of the diol or polyol with an acidic resin under conditions such that the cyclic alkanediol or polyol is converted to a compound having a boiling point sufficiently different (eg by at least about 10 degrees C) to permit separation of the compound from the linear form of the diol or polyol by, for example, distillation.
