Abstract
Un procedimiento para la preparación de un complejo de cromo asimétrico 1:2. La preparación de los complejos de cromo 1:1 a partir de compuestos de fórmula II o III puede llevarse a cabo según métodos conocidos. Los materiales de partida de fórmula II o III pueden prepararse de manera convencional. La reacción según el procedimiento a) y b) puede realizarse de modo habitual. Para obtener los complejos de cromo asimétricos 1:2, la reacción se efectúa ventajosamente a un pH de 6 a 11 dependiendo del contenido de sal de las materias de partida, de preferencia a un pH de 7 a 9. Conviene utilizar los componentes de la reacción en cantidades aproximadamente estequiómetricas, evitando un exceso de colorante monoazoico libre de metal. El producto obtenido puede aislarse y purificarse de acuerdo con métodos conocidos; el producto puede, por ejemplo, precipitarse por adición de sal o de un ácido débil, lavarse luego con una solución concentrada de sal y secarse.
