| abstract | The invention discloses the catalyst that a kind of hydrogenation catalyst synthesizes the method for the disulfonate sodium of 8 amino, 1 naphthols 3,6 and its used.The catalyst is activated carbon supported type nickel-molybdenum iron three-way catalyst；This method is pre-processed using nitro T ammonium salts reaction solution as reaction raw materials by the pH tone pitches of reaction raw materials, then carries out hydrogenating reduction with activated carbon supported type nickel-molybdenum iron three-way catalyst, then the disulfonate sodium of 8 amino, 1 naphthols 3,6 is made by alkali fusion, acid out.The catalyst of the present invention, which has, to be prepared simple, nitro T ammonium salts effectively can be reduced into amino T ammonium salts, and can effectively be solved during hydrogenating reduction catalyst poisoning, rapid deactivation and can be applied mechanically the low problem of recovered frequency；The synthetic method of the present invention substantially increases the yield of hydrogenation catalyst technique, product purity, reduces the generation of waste water and the pollution of environment, and processing step is easy, safety, stable reaction, it is easy to control. |
