Abstract
A process for the preparation of pentachlorothiophenol, comprising the formation of a reaction system by mixing a molar amount of hexachlorobenzene to be converted to pentachlorothiophenol, with an amine compound as solvent carrier, consisting of (1) a minimum of two molecules of an alkyl low molecular weight tertiary amine, having as substituent alkyl groups, with a maximum content of 8 carbon atoms (2) and from 1 to 100 moles, per mole of said alkyl amine, of a tertiary amine N-heterocyclic which is aromatic and has in its structure one to two heterocyclic nitrogen atoms in an annular configuration selected from the group consisting of (a) monocyclic nuclei of nitrogen and carbon of six bonds, and (b) bicyclic nuclei of nitrogen and carbon of ten. Bonds, and containing a maximum of 20 carbon and nitrogen structural atoms in its entire molecular structure, the aforementioned aromatic tertiary amine N-hete the cyclic must have at least one open position close to one of the functional aromatic nitrogen atoms in the cyclic structure; by subjecting the aforementioned hexachlorobenzene, while in said system, at a temperature of from 75 to 150º c, in the presence of at least a stoichiometric amount of hydrogen sulfide, until at least a part of said hexachlorobenzene is converted to pentachlorothiophenol.
