Abstract

"PROCESSO PARA A PREPARAçãO DE COMPOSTOS DE HIDROXIDIFENILA HALOGENADOS". é descrito um processo para a preparação de compostos de hidroxidifenila halogenados da fórmula (1) por acilação de um composto de benzeno halogenado (primeiro estágio), eterificação do composto acilado com um composto de fenol halogenado, o qual não está adicionalmente substituído na posição orto (segundo estágio), oxidação do composto eterificado (terceiro estágio) e hidrólise do composto oxidado em um quarto estágio, em que a reação do segundo estágio é realizada na presença de K~ 2~CO~ 3~ e qualquer catalisador de cobre desejado, onde o K~ 2~CO~ 3~ é usado em uma concentração de 0,5 a 30 moles, com base no composto de fenol empregado da fórmula (6), de acordo com o seguinte esquema de reação: em que R~ 1~ e R~ 2~ independentemente um do outro são F, CI ou Br; R~ 3~ e R~ 4~ independentemente um do outro são hidrogênio; ou C~ 1~-C~ 4~ alquila; m é 1 a 3; e n é 1 ou 2. Os compostos da fórmula (1) são usados para a proteção de materiais e artigos orgânicos de microorganismos.
