Abstract:
Sulfides of Group IVb and Vb transition metals are produced by reacting their halides with carbon disulfide. The reactions can be between liquid or gaseous halides and liquid or gaseous carbon disulfide. The reaction products are formed and recovered as solids and the other reaction product, carbon tetrahalide, is carried off as a gas and recovered. A specific example is the production of titanium disulfide by reacting titanium tetrachloride with carbon disulfide.
