Abstract
CUANDO SE OBTIENEN SOLUCIONES ACUOSAS DE ALTA CONCENTRACION, DE COLORANTES AZO, POR EL METODO DIRECTO DE REACCIONES DE DIAZOTIZACION Y ACOPLAMIENTO, SURGEN CON ELLO DIFICULTADES CONSIDERABLES, PORQUE EN EL TRANSCURSO DE LAS REACCIONES DE DIAZOTIZACION Y ACOPLAMIENTO, SE PRESENTAN FASES VISCOSAS QUE CONDUCEN A PROBLEMAS DE AGITACION EN LOS APARATOS DE REACCION UTILIZADOS, LO QUE POR SU PARTE TIENE COMO CONSECUENCIA UNA SINTESIS INCOMPLETA. CON EL NUEVO PROCEDIMIENTO PARA LA OBTENCION DE SOLUCIONES COLORANTES ACUOSAS CONCENTRADAS, DE UN COLORANTE ANIONICO EN UN MEDIO ACUOSO, SE SOLUCIONO ESTE INCONVENIENTE, EN EL QUE LA DIAZOTIZACION DE LA AMINA AROMATICA UTILIZADA COMO COMPONENTE DIAZO Y/O LA REACCION DE ACOPLAMIENTO, ENTRE LA SAL DE DIAZONIO Y EL COMPONENTE DE ACOPLAMIENTO, SE REALIZA EN PRESENCIA DE UN AGENTE AUXILIAR, EL CUAL EJERCE UNA ACCION REDUCTORA DE LA VISCOSIDAD EN LAS FASES PASTOSO-VISCOSAS. COMO TALES AGENTES AUXILIARES PUEDEN UTILIZARSE, POR EJEMPLO, PRODUCTOS DE CONDENSACION DE ACIDO NAFTALINSULFONICO FORMALDEHIDO, DADO EL CASO SUSTITUIDO POR ALQUILO, SULFONATOS DE LIGNITO, POLIACRILATOS Y COPOLIMERIZADOS DE ANHIDRIDO DE ACIDO MALEICO O ACIDO ACRILICO.
