Abstract

Patente de Invenção: <B>"PROCESSO PARA A PREPARAçãO DE COMPOSTOS 4,4'-DIHALOGêNIO-O-HIDRóXI DIFENILA"<D>. A invenção refere-se a um processo de quatro - etapas para a preparação de compostos 4,4'-dihalogênio-o-hidróxi difenila de fórmula por halogenação de um composto difenila (etapa 1a) ou pela reação de p-halofenol e p-dihalofenol (etapa 1b), acilação do composto dihalogênio em uma reação de Friedel-Crafts (2¬ etapa), oxidação do composto acila (3¬ etapa) e hidrólise (4¬ etapa). Os compostos de fórmula (1) são usados para proteção de materiais orgânicos e objetos de microorganismos.
