METHOD OF SYNTHESIS OF METAL SULFIDE Russian patent published in 2002 - IPC

FIELD: inorganic chemistry, chemical technology. SUBSTANCE: method involves the precipitation of sulfides in liquid alkanes medium in the presence of sulfur. Metal salt with decomposition point below 200 C is used as a metal-containing reagent. A mixture of metal salt with sulfur is added by batch regime by 0.1-0.5 part for 4 h to liquid hydrocarbon containing sulfur and heated preliminary to a boiling point. Metal salt and sulfur are taken in the mole ratio = 1 : (0.55-4). Invention ensures to decrease the synthesis time to 4 h. Invention can be used in preparative syntheses and technology of production of luminescent semiconductor materials, sulfide dyes and solid lubricants. EFFECT: improved method of synthesis, decreased energy consumption. 1 tbl
