Abstract

PROCEDIMIENTO PARA LA OBTENCION DE COLORANTES MONOAZOICOS METALIZABLES. PROCEDIMIENTO PARA LA OBTENCION DE COLORANTES MONOAZOICOS METALIZABLES, DE FORMULA (I), EN DONDE A ES UN RADICAL BENCENO, ALQUILO DE 1-6 CARBONOS, Y OTROS, Y B ES UN RADICAL NAFTALENO QUE PUEDE ESTAR SUSTITUIDO CON GRUPOS AMINO, FENILAMINO, ALQUILAMINO DE 1-6 CARBONOS Y SULFONICOS, EN DONDE ESTOS GRUPOS ESTAN EN POSICION ORTO A LOS GRUPOS HIDROXILO. EL PROCEDIMIENTO CONSISTE EN QUE UNA AMINA DE FORMULA (II) SE DIAZOTA EN MEDIO ACUOSO Y, EN PRESENCIA DE PIRIDINA O DE BASES PIRIDICAS, SE COPULA CON UN COMPONENTE DE COPULACION DE FORMULA (III). EL COLORANTE AZOICO FORMADO SE SEPARA DE LA PIRIDINA A BASES PIRIDICAS POR DESTILACION CON ARRASTRE CON VAPOR, O SE SEPARA POR PRECIPITACION, EN PRESENCIA DE ACIDO Y SE FILTRA. LA PIRIDINA O BASES PIRIDICAS, UNA VEZ AJUSTADO EL PH A 7-10 SE PURIFICAN POR DESTILACION CON ARRASTRE CON VAPOR. ESTOS COLORANTES AZOICOS AL CROMO SE PUEDEN USAR PARA TEÑIR LANA ENTRE OTROS USOS.
