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.
