Abstract
By means of reducing or thermal cracking, spent sulphur-containing sorbents obtained from waste organochlorine products can be converted into valuable organosulphur products such as 1,2-dithiol-3-thione, or 1,2,3-tris(methylsulphanyl)propane. The metal contained in the sorbent in both cases is transformed into corresponding sulphide and could be used to produce the metal in the usual way.
