Abstract
In accordance with the present invention, methods have been developed for the reduction of the chloride content of epoxy compound starting materials. Invention methods comprise fractionating an epoxy compound starting material into portions (e.g., fractions or cuts) having different chloride content relative to the epoxy compound starting material. Certain of these collected portions (i.e., the portions fractionated and collected after collection of the forecut and before discontinuation of the fractionation) contain substantially reduced chloride levels relative to the epoxy compound starting material.
