ABSTRACT:
An object is to provide a method for the production of a sulfide group-containing thiol compound which comprises using a solvent capable of effecting the ring-opening addition reaction of an alkylene sulfide to a thiol compound without inducing the alkylene sulfide to polymerize. A method for the production of a sulfide group-containing thiol compound, which comprises effecting the ring-opening addition reaction of an alkylene sulfide represented by the general formula (1): ##STR1## (wherein R.sup.1, R.sup.2, R.sup.3, and R.sup.4, which may be identical or different, stand for a hydrogen atom, an alkyl group of 1 to 10 carbon atoms, or an aromatic group of 6 to 15 carbon atoms) to a thiol compound in a solvent of an amide compound or urea substituent-containing compound.
