Abstract
PROCEDIMIENTO DE OBTENCION DE 2,6-DICLORO-4-NITROANILINA. CONSISTE EN LA CLORACION MEDIANTE CLORO GASEOSO DE LA PARANITROANILINA EN SOLUCION ACUOSA DE ACIDO CLORHIDRICO, CON EBULLICION. LA REACCION TIENE LUGAR A UNA TEMPERATURA COMPRENDIDA ENTRE 95 Y 110 GRADOS CENTIGRADOS. LA CONCENTRACION DEL MEDIO ACIDO OSCILA ENTRE 4 Y 7,5 N. PREFERENTEMENTE SE TRABAJA CON UNA CONCENTRACION DE 1 MOL DE AMINA POR LITRO DE ACIDO CLORHIDRICO. ES NECESARIO QUE AL FINAL DE LA OPERACION NO RE SULTE SOBRESTURADO EL MEDIO, YA QUE DE SER ASI SE DESGASARIA EL ACIDO EN EXCESO Y COMPETIRIA CON EL CLORO EN SU PASO HACIA EL LIQUIDO, LO QUE AUMENTARIA LA DURACION DE LA REACCION.
