Abstract

PROCEDIMIENTO DE OBTENCION DE COLORANTES CATIONICOS DE HIDRAZONA. CONSISTE EN HACER REACCIONAR BASES AZOICAS DE FORMULA GENERAL I CON DIMETILSULFONATO EN UNA MEZCLA DE AGUA Y EN UN DISOLVENTE ORGANICO, EN PRESENCIA DE UN ACEPTOR DE ACIDO, EMPLEANDOSE COMO DISOLVENTE ORGANICO UN HIDROCARBURO CLORADO AROMATICO O ALIFATICO. LA REACCION SE EFECTUA A UNA TEMPERATURA COMPRENDIDA ENTRE 10 Y 60GC, EMPLEANDO UN EXCESO DE 5-90 POR 100 DE DIMETILSULFONATO Y DESARROLLANDO LA REACCION A UN PH COMPRENDIDO ENTRE 5 Y 10. COMO HIDROCARBURO CLORADO SE EMPLEA 1,2-DICLOROPROPANO. COMO MEDIO ACEPTOR DE ACIDO SE EMPLEA HIDROXIDO SODICO, UTILIZANDO UN DISPOSITIVO DOSIFICADOR REGULADO POR EL PH. *FORMULA*
