Abstract: The alkyl groups of dialkyl trisulfides are exchanged with the alkyl groups of mercaptans by reacting a tertiary dialkyl trisulfide with an alkyl mercaptan having a greater number of carbon atoms in its alkyl group than said trisulfide in the presence of an acidic or basic type catalyst for a time and a temperature sufficient to produce a dialkyl trisulfide having at least one transferred alkyl group from said mercaptan.

Abstract: A process is disclosed for the preparation of unsymmetrical dialkyl trisulfides by the reaction of dialkyl trisulfides and olefins in the presence of an acidic-type catalyst whereby alkyl groups are exchanged. Novel mixtures of symmetrical and unsymmetrical dialkyl trisulfides are also disclosed.
