Abstract

Un procedimiento de producir un pigmento del tipo de ftalocianina de cobre caracterizado por el hecho de que un orto-dinitrilo aromático se hace reaccionar en ausencia de agua con sulfato cúprico en presencia de un diluyente orgánico prácticamente inerte líquido a la temperatura de la reacción y en presencia de por lo menos suficiente amoniaco para combinarse con el anión sulfato que queda libre en la reacción para producir sulfato amónico y nitrógeno.
