Abstract：N-nitro-2,4,6-Trichloroaniline was synthesized from aniline with acetyl nitrate as nitrating agent. The factors affecting the yield of trichloroaniline are reaction temperature, reaction time, and the mole ratio of raw materials.The optimum conditions are as follows: reaction temperature is 14℃; reaction time is 1?h; the mole ratio of acetyl nitrate and trichloroaniline is 1∶1. Under the conditions, the yield of product is over 90%. The structure of the product were characterized by elemental analysis, IR,...

Key words：N-nitro-2; 4; 6-Trichloroaniline; synthesis; yield
