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.Invention Patent: <B> "PROCESS FOR THE PREPARATION OF 4,4'-DIHALOGEN-O-HYDROXY DIPHENYL COMPOUNDS" <D>. The invention relates to a four-step process for the preparation of 4,4'-dihalogen-o-hydroxy diphenyl compounds of formula by halogenation of a diphenyl compound (step 1a) or by the reaction of p-halophenol and p- dihalophenol (step 1b), acylation of the dihalogen compound in a Friedel-Crafts reaction (2nd step), oxidation of the acyl compound (3rd step) and hydrolysis (4th step). The compounds of formula (1) are used to protect organic materials and objects from microorganisms.
