Abstract

"MELHORAMENTO DO PROCESSO DE BROMAçãO PELA RECUPERAçãO DE RESìDUOS CATALìTICOS DE TRIHALETO DE ANTIMÈNIO". Um processo para bromação no qual um polímero estirênico em um solvente orgânico na presença de um catalisador de trihaleto de antimónio tal que uma massa de reação contendo polímero estirênico em uma fase orgânica é formada sendo melhorada pela mistura do ácido hidroclorídrico ou ácido hidrobrómico, ou ambos, com a dita massa de reação de pelo menos uma vez para extrair resíduos catalíticos de antimónio da dita massa de reação como uma fase aquosa ácida. Preferivelmente, resíduos catalíticos são recuperados da fase aquosa ácida e ainda mais preferivelmente, recuperados resíduos catalíticos de trihaleto de antimónio que estão reciclados para constituir pelo menos uma porção de catalisador trihaleto de antimónio usado na preparação do polímero estirênico bromatado.
