PROCESS FOR PRODUCING AMMONIUM POLYTHIOMOLYBDATE OF THE FORMULA (NH4) 2MO3S13.N H 2O |
摘要 |
There is disclosed a process for producing an ammonium polythiomolybdate of the formula (NH<SUB>4</SUB>)<SUB>2</SUB>MO<SUB>3</SUB>S<SUB>13</SUB>.nH<SUB>2</SUB>O where n is 0, 1 or 2 comprising reacting an aqueous ammoniacal molybdate solution with hydrogen sulfide gas at superatmospheric pressure until the H<SUB>2</SUB>S is no longer absorbed by the solution, said solution and said gas being in a closed system and the flow of said gas being regulated at an elevated pressure, to form a slurry consisting essentially of a solid essentially all of which is ammonium tetrathiomolybdate, and thereafter heat soaking the reaction product at elevated temperature in the presence of elemental sulfur to form the desired product. |
