Abstract

PROCEDIMIENTO DE OBTENCION DE COMPUESTOS DE NITROARILO SUSTITUIDOS. CONSISTE EN EFECTUAR UNA NITRACION CON ACIDO NITRICO EN UN SISTEMA BIFASICO CONSTITUIDO POR UNA FASE INORGANICA DE ACIDO SULFURICO AL 80 POR 100 O MAS Y UNA FASE ORGANICA EN LA QUE EL PRODUCTO DE NITRACION ES INSOLUBLE. LA TEMPERATURA DE REACCION OSCILA ENTRE 30G Y 100GC; LOS LIQUIDOS ORGANICOS EMPLEADOS SON EL CLOROBENCENO, EL O-DICLOROBENCENO, EL TETRACLOROBENCENO Y BENCINAS. EL ACIDO SULFURICO SE EMPLEA EN CANTIDAD DE 300 AL 1.000 POR 100 EN PESO RESPECTO A LA CANTIDAD DEL SUSTRATO DE REACCION. LA REACCION DE NITRACION SE EFECTUA CON SULFURICO CONCENTRADO Y ACIDO NITRICO, TAMBIEN CONCENTRADO, EN RELACION PONDERAL 1:1, LA OPERACION SE EFECTUA EN CONTINUO. E
