Abstract

A method for the removal of soluble tellurium compounds from vicinal glycol ester solutions, prepared with tellurium-halide ion catalyst systems, by diluting the tellurium-containing vicinal glycol ester solution with water and contacting said glycol-water solution with a strongly acidic sulfonated ion exchange resin leaving an essentially tellurium-free vicinal glycol ester reaction product which may then be processed to recover the desired ester product and by-products without loss of valuable tellurium. The tellurium may be recovered from the ion exchange resin and treated to recover tellurium in a form suitable for reuse.
