Abstract

Patente de Invenção: "CORANTES AZO AMARELO E AZOESTILBENO". Mistura de corantes azo amarelo e azoxiestilbeno tendo a tonalidade de um corante C.I. Direct Yellow 11 pode ser obtido partir da autocondensação do ácido 4,4'-dinitro-2,2'-estilbenodissulfónico na presença de um hidróxido de metal alcalino e de um excesso de formaldeído além daquele necessário para a conversão do ácido 4,4'-dinitro-2,2'-estilbeno dissulfónico para Direct Yellow 6. Podem ser obtidas soluções aquosas concentradas dos corantes através da conversão do sal de metal alcalino do corante pouco solúvel em água em um sal de alcanolamónio solúvel em água por uma dupla troca de cátions através de um sal lipofílico de amónio, em cujo processo a dupla troca de íon é executada em um sistema de duas fases de metil isobutil cetona e água, e com a utilização para a primeira troca de íon de uma tri alquilamina contendo um total de 12 até 40 átomos de carbono e para a Segunda troca de íon, uma mono-, di-, ou tri alcanoiamina contendo de 2 a 4 átomos de carbono em cada uma das porções de alquila. Os corantes são especialmente úteis para a tintura de papel.
