ABSTRACT:
The present invention discloses a method for producing a hydroxylamine compound wherein a nitro compound is contacted with a hydrogen source or further with a poisoning agent in the presence of a platinum catalyst fixed on an ion-exchange resin. According to the method of the present invention where a platinum catalyst fixed on a matrix of an ion-exchange resin is used, the objective hydroxylamine compound can be produced (manufactured) efficiently, more industrially and safely with little formation of a byproduct. Further, the platinum catalyst fixed on an ion-exchange resin of the present invention is hardly deactivated even if repeatedly used many times because platinum metal is fixed on a matrix of the ion-exchange resin, and handling in recovery, reuse and the like of said catalyst is extremely easy because particle size of said catalyst is very large.
