Abstract

"PROCESSO PARA PRODUçãO DE BISFENOL A". No processo para produção de bisfenol A que consiste em cristalizar um aduto de bisfenol A e fenol a partir de uma solução de bisfenol A em fenol, obtida por reação de fenol com acetona na presença de um catalisador ácido; tratar a pasta fluida formada por separação sólido-líquido; e remover o fenol do componente sólido; é formada uma camada de aduto em um filtro, por filtração da pasta fluida (1) contendo o aduto cristalino; a camada de aduto é lavada com um líquido de lavagem; sendo, em seguida dissolvida em uma solução contendo fenol, produzindo, por cristalização, uma pasta fluida (2) contendo o aduto cristalino; separa-se o aduto cristalino por centrifugação da pasta fluida (2). Quando bisfenol A é separado da mistura de reação, o aduto de bisfenol A e fenol pode ser recuperado do licor-mãe da reação eficientemente, em alta pureza de acordo com o processo acima.
