ABSTRACT:
Disclosing a process for making meta-aminobenzotrifluoride comprising:
reacting meta-nitrobenzotrichloride with hydrogen fluoride in the presence of ammonium ions under a pressure of at least about 35 psig and at a temperature of at least about 55.degree. C. for sufficient time in the presence of water and a metal catalyst to form meta-aminobenzotrifluoride, wherein the amount of water added is at least one mole percent of the meta-nitrobenzotrichloride.
