ABSTRACT:
A process for the preparation of a thiobis-2,6-disubstituted phenol is described which comprises the reaction of sulfur with a 2,6-disubstituted phenol carried out in the presence of (1) a base, (2) and an activated olefin or an epoxy compound. Thiobisphenols produced by this process are useful as monomers in the synthesis of polyesters, polycarbonates, polyethers, epoxy resins, among many other chemicals synthesized from polyhydric phenols. In addition, the thiobisphenols are also useful as antioxidants.
