Abstract

Patente de Invenção: <B>"PROCESSO DE OXIDAçãO PARA PREPARAR PIGMENTOS DE QUINACRIDONA"<D>. Processo para preparar uma quinacridona não-substituída ou substituída da fórmula: ou uma solução sólida de quinacridonas da fórmula (I), em que X e Y são independentemente 1 ou 2 substituintes selecionados de hidrogênio, flúor, cloro, alquil C~ 1~-C~ 3~, alcóxi C~ 1~-C~ 3~ e COOR em que R é hidrogênio ou alquil C~ 1~-C~ 10~, em que um sal de uma 6,13-dihidroquinacridona da fórmula II tendo as mesmas substituições como a quinacridona desejada da fórmula I, ou uma mistura das 6,13-dihidroquinacridonas correspondentes da fórmula II, é oxidada com um gás contendo oxigênio na presença de uma base aquosa e uma quantidade cataliticamente eficaz de um catalisador de oxidação, em que a oxidação é realizada na presença de um meio de reação poliglicólico da fórmula R~ 1~-O-[(CH~ 2~)~ m~-(CHR~ 1~')~ n~-O]~ X~-O-R~ 1~" (III).
