Abstract
Procedimiento para la obtención de colorantes azoicos con grupos ácido sulfónico de fórmula I **fórmula** en la que R1 significa un átomo de hidrógeno o un radical alquilo o alcoxi sustituido o sin sustituir que contiene de 1 a 6 átomos de carbono, R2 significa un átomo de hidrógeno o un radical alquilo sustituido o sin sustituir que contiene de 2 a 4 átomos de carbono, R3 significa un radical alquilo alquilo sustituido o sin sustituir que contiene de 2 a 4 átomos de carbono, R4 significa un átomo de hidrógeno, un radical fenilo sustituido o sin sustituir o bien un radical alquilo o alcoxi que contiene de 1 a 6 átomos de carbono y que lleva como mínimo un sustituyente del grupo que consiste en cloro, bromo, hidroxilo, aciloxi, ciano, tiocianato, nitro y alcoxi, alquilsulfonilo o alquiltio, los tres últimos pueden estar sin sustituir o sustituidos y contienen de 1 a 6 átomos de carbono, el anillo A es sins sustituir o bién sustituido, y el anillo B puede estar, en caso dado, sustituido ulteriormente a condición de que los compuestos no contengan grupos de ácido sulfónico, caracterizado por el hecho de que se hace reaccionar un derivado de diazonico o de nitrosamina.
