Abstract

L'INVENTION A TRAIT AU DOMAINE DE LA CHIMIE TINCTORIALE. ELLE CONCERNE UN PROCEDE DE PRODUCTION DE COLORANTS AZOIQUES CONTENANT DU CUIVRE DE FORMULE: (CF DESSIN DANS BOPI) (DANS LAQUELLE R REPRESENTE H, UN RESTE ACETYLE, BENZOYLE OU PHENYLE EVENTUELLEMENT SUBSTITUE, N EST EGAL A 1 OU 2 ET X EST LE PONT AZO ETOU AZOXY) PAR TRAITEMENT, AVEC DES AGENTS CEDANT DU CUIVRE, PAR EXEMPLE DE COMPOSES OBTENUS A PARTIR DE 5-NITRO-2-AMINO-ANISOLE PAR DIAZOTATION ET COPULATION SUR UN ACIDE HYDROXYNAPHTALENESULFONIQUE, PUIS REDUCTION DU COMPOSE OBTENU. LE PROCEDE DE L'INVENTION PERMET D'OBTENIR DE TRES BONS RENDEMENTS.THE INVENTION RELATES TO THE FIELD OF TINCTORIAL CHEMISTRY. IT CONCERNS A PROCESS FOR THE PRODUCTION OF AZOIC DYES CONTAINING COPPER OF FORMULA: (CF DRAWING IN BOPI) (IN WHICH R REPRESENTS H, AN ACETYL, BENZOYL OR PHENYL REMAINDER WHICH IS POSSIBLE SUBSTITUTED, N IS EQUAL TO 1 OR 2 AND X IS THE BRIDGE AZO ETOU AZOXY) BY TREATMENT, WITH COPPER LOWING AGENTS, FOR EXAMPLE OF COMPOUNDS OBTAINED FROM 5-NITRO-2-AMINO-ANISOLE BY DIAZOTATION AND COPULATION ON A HYDROXYNAPHTALENESULFONIC ACID, THEN REDUCTION OF THE COMPOUND OBTAINED. THE PROCESS OF THE INVENTION ALLOWS VERY GOOD RETURNS TO BE OBTAINED.
