Abstract
and 2,6-Tolylenediamines are prepared by the catalytic reduction of 2,4- and 2,6-dinitrotoluene in toluene wiht ammonia synthesis gas, which may be fresh or recycled gas, at 150 degrees C and 50 atm. in the presence of a Raney copper catalyst. Higher yields of the tolylenediamines are obtained, generally in the range 96-99%.
