Abstract：2-Chloroaniline,which is an important chemical intermediate,was synthesized from 2-Chloroaniline with hydrazine hydrate by using Fe-Al complex as catalyst. The results showed that the selectivity of the catalytic reaction is over 99%. The reaction temperature was 70℃. The mole ratio was n(1-chloro-2-nitrobenzene):n(hydrazine hydrate)= 1.0:1.8. The yield and content of 2chloroaniline are 93.7% and 99.5%.

Key words：Fe-Al complex catalyst; hydrazine hydrate; selectivity; reduction; 2-chloro-1-nitrobenzene; 2-chloroaniline
