METHOD OF PRODUCING NITROSYL CHLORIDE COMPOUNDS OF PALLADIUM Russian patent published in 2016 - IPC C01G55/00 C01B9/02 C01B21/84 

FIELD: metallurgy.

SUBSTANCE: invention can be used for preparation of organometallic compounds of palladium or palladium-containing materials. Method for preparing nitrosyl-chloride compounds of palladium comprises reacting palladium nitrate with a solution of formic acid or formic acid and sodium formate, or successive reaction with nitrogen oxide NO and with formic acid. Obtained solution is then introduced into a mixture of hydrochloric and glacial acetic acid and precipitated-nitrosyl-chloride compounds of palladium of composition Pd(NO)₂Cl₂ or Pd(NO)Cl. Palladium nitrosyl-chloride of composition Pd₂(NO) Cl₂ is prepared by solid-phase decomposition of palladium nitrosyl-chloride of composition Pd(NO)Cl.

EFFECT: invention provides stable production of nitrosyl-chloride compounds of palladium in high yield and in chemically pure homogeneous phase state.
