Abstract

PROCEDIMIENTO PARA LA PREPARACION DE COLORANTES COMPLEJOS DE CROMO. CONSISTE EN HACER REACCIONAR UN COLORANTE DE FORMULA (I), CON UN AGENTE DONADOR DE CROMO, PARA FORMAR UN COMPLEJO DE CROMO 1:1, Y A CONTINUACION HACER REACCIONAR ESTE CON EL COLORANTE DE FORMULA (II), ELIGIENDO LOS COMPUESTOS DE MODO QUE EL COMPLEJO DE CROMO CONTENGA DE 1 A 8 GRUPOS SULFO, SIGNIFICANDO B Y A RADICALES DE LA SERIE BENCENICA O NAFTALINICA. Y UN ATOMO DE OXIGENO O UN GRUPO DE FORMULA -NR-, D EL RADICAL DE UN O-HIDROXIALDEHIDO, X PUEDE SER UN ENLACE DIRECTO O UNA DIAMINA ALIFATICA, AROMATICA O HETEROCICLICA, Z ES UN ATOMO DE HIDROGENO O UN GRUPO CH, Y R1 Y W PUEDEN SER RADICALES ALQUILICOS. UNA ALTERNATIVA A ESTE PROCEDIMIENTO ES HACER REACCIONAR EL AGENTE DONADOR DE CROMO CON EL COMPUESTO DE FORMULA (II) Y EL COMPLEJO DE CROMO OBTENIDO HACERLO REACCIONAR CON EL COMPUESTO DE FORMULA (I). *FORMULA*
