Abstract

Procedimiento para obtener 2-hidroxibenzantrona y los derivados de substitución respectivos cubiertos por la fórmula general: **(Fórmulas)** Los compuestos obtenidos según este invento encuentran una aplicación útil como intermediarios para colorante y pigmentos. La 2-hidroxibenzantrona constituye un importante intermediario conocido desde hace tiempo y utilizado para la preparación del colorante a la tina C.I. 1101. Los derivados de 2-hidroxibenzantrona substituidos en las posiciones 6, 8, 9 y 10 con grupos OH, OCH3, O1, NH-CO-C6H5, son de por sí nuevos y es precisamente sobre estos nuevos productos a los que se pretende extender el alcance del invento.
