Abstract
A process which can be used to produce organic polysulfide compounds is provided. The process comprises contacting, in the presence of a catalyst, a mercaptan with sulfur under conditions sufficient to produce an organic polysulfide and thereafter, the resulting reaction medium is contacted with an acid to produce an acid-treated organic polysulfide wherein the mercaptan, sulfur, and catalyst are each present in an amount effective to produce an organic polysulfide. The acid-treated organic polysulfide can be purified and recovered.
