<P>PROBLEM TO BE SOLVED: To provide a method for production of 4-nitrodiphenylamine, which is continuously synthesizable and enables the post-treatment of a reaction mixture to be simply performed. <P>SOLUTION: The method for production of 4-nitrodiphenylamine is characterized by reacting aniline with nitrobenzene in the presence of a solid catalyst in a fixed-bed flow system. The solid catalyst is preferably at least one selected from the group consisting of alkali metal fluorides supported by a carrier and composite oxides. <P>COPYRIGHT: (C)2012,JPO&INPIT |
