    摘要： Preparation process for 3,4-disubstituted dinitroanilines of formula ##STR1## in which, R.sub.1 and R.sub.2, which are identical to or different from one another, represent a hydrogen atom, a C.sub.1 to C.sub.6 saturated, linear or branched alkyl radical, a C.sub.2 to C.sub.6 linear or branched alkylene radical, a cyclopropyl radical or a chloroethyl radical,R.sub.3 and R.sub.4, which are identical to or different from one another are chosen from the group containing the chlorine atom, the amino group, the C.sub.1 to C.sub.3 lower alkyl radicals and the trifluoromethyl radical,comprising successively a dinitration stage of a 3,4-disubstituted phenol, an alkylation stage of the dinitrated derivative thus obtained and an amination stage of the 3,4-disubstituted 2,6-dinitro-alkoxybenzene thus obtained.
