The paper shows the experimental results of the hydrochloride chlorina
tion reaction in acetic acid medium, in the FeCl3 presence. The influe
nce various parameters have upon the chlorination process, in the 4-ch
lorine-2-aminotoluene hydrochloride production, is presented. The opti
mum molar ratio between the reagents and a variable temperature regime
for a process maximum selectivity were established
