METHOD OF PRODUCTION OF MOLYBDENUM OR TUNGSTEN SULFIDE Russian patent published in 2002 - IPC

Abstract RU 2184082 C2

FIELD: inorganic chemistry, chemical technology. SUBSTANCE: sulfides are precipitated in medium of liquid alkanes in the presence of sulfur. Molybdenum or tungsten salts of type M2EO4, where M is NH+4

, K+; E is Mo, W are used as a metal-containing reagent. The parent reagents are taken in the ratio M : S = 1 : (4.0-5.2). Synthesis is carried out at 150-200 C for 4-8 h. The indicated ratio of components ensures to increase the yield of molybdenum or tungsten sulfides up to 90%. Invention can be used in technology of production of solid lubricants, catalysts in an organic synthesis, transformers of heat energy. EFFECT: improved method of synthesis, increased yield. 1 tbl, 7 ex
