Method for hydrogen catalyzed preparation of 1-naphthylamine-8-sulfonic acid

The invention discloses a method for hydrogen catalyzed preparation of 1-naphthylamine-8-sulfonic acid. The method includes the reduction steps of: placing a solution containing 1-sulfonyl-8-nitronaphthalene in a reduction pot, adding nickel powder, conducting starting and stirring, enclosing the reduction pot and pumping vacuum, then introducing hydrogen and maintaining the pressure at 1.2-1.3MPa, heating the mixed liquid to a temperature of 100-110DEG C, pumping out the mixed liquid from the bottom continuously and letting it flow into the reduction pot from the top, at the same time pumping out the gas from the top continuously and blowing the gas into the reduction pot from the bottom. The method for hydrogen catalyzed preparation of 1-naphthylamine-8-sulfonic acid provided by the invention can prepare the 1-naphthylamine-8-sulfonic acid product meeting the market requirements, and also can overcome the disadvantages of existing iron powder catalyzed preparation methods.
