发明名称 Process for producing 2-(p-chlorophenoxy) aniline
摘要 2-(p-chlorophenoxy)aniline is prepared in a process which provides improved yields and reduction of key impurities. A solution comprising 2-(p-chlorophenoxy)nitrobenzene, o-dichlorobenzene, and a platinum catalyst is prepared followed by the addition thereto of hydrazine hydrate in water. The temperature is maintained at 80 DEG C. to 110 DEG C. during the addition and until completion of the reaction. The reaction mixture is then cooled to 20 DEG C. to 40 DEG C. and filtration, washing, and distillation workup steps follow.
