Patent ID: 7618914

Claim:
A method for producing a hydroxylamine compound, comprising: contacting a nitro compound with a hydrogen source in the presence of a platinum catalyst fixed on an ion-exchange resin, wherein the hydrogen source is hydrazine and the platinum catalyst fixed on an ion-exchange resin is obtained by adsorbing a platinum-containing ion in an aqueous solvent derived from a platinum compound with the ion-exchange resin followed by subjecting the ion to a reductive treatment, and the platinum compound is selected from the group consisting of ammonium hexachloroplatinate, ammonium tetrachloroplatinate, potassium hexachloroplatinate, potassium tetrachloroplatinate, potassium tetrabromoplatinate, sodium hexachloroplatinate, sodium tetrachloroplatinate, platinum nitrate, platinum sulfate, platinum acetate, and platinum complexes coordinated with a ligand selected from the group consisting of 1,5-cyclooctadiene (COD), dibenzylideneacetone (DBA), norbornadiene (NBD), tricyclohexylphosphine (PCγ 3 ), triethoxyphosphine (P(OEt) 3 , tri-tert-butylphosphine (P(O′Bu) 3 , bipyridine (BPY), phenanthroline (PHE), triphenylphosphine (PPh 3 ), 1,2-bis(diphenylphosphino)ethane (DPPE), triphenoxyphosphine (P(OPh) 3 ), trimethoxyphosphine (P(OCH 3 ) 3 ), ethylene (CH 2 ═CH 2 ), amine(NH 3 ), N 2 and PO 3 .
