Abstract

PROCEDIMIENTO PARA LA OBTENCION DE COMPLEJOS DE COBRE DE COLORANTES POLIAZOICOS. CONSISTE EN COPULAR EL 1,3-DIHIDROXIBENCENO CON UNA SAL DE DIAZONIUM DEL COMPONENTE DIAZOICO DE LA SERIE BENCENO QUE LLEVA UN GRUPO AMINO; DICHA COPULACION SE EFECTUA EN PRESENCIA DE UN COMPUESTO CEDEDOR DE IONES CU2+ A UNA TEMPERATURA COMPRENDIDA ENTRE 20 Y 40 C. EL PRODUCTO DE COPULACION QUE SE FORMA NO SE AISLA INTERMEDIARIAMENTE ANTES DE LA REACCION POSTERIOR CON LA SAL DE DIAZONIUM DEL COMPONENTE DIAZOICO DE LA SERIE BENCENO QUE LLEVA DOS GRUPOS AMINO. EL COMPUESTO CEDEDOR DE IONES CU2+ EMPLEADO ES SULFATO DE COBRE. SE OBTINE EL COMPUESTO DE FORMULA GENERAL (I).
