Abstract

Patente de Invenção: <B>''PURIFICAçãO DE 1,1,1,3,3-PENTAFLUOR-BUTANO''<D>. A invenção descreve a preparação de 1,1,1,3,3-pentafluorbutano (HFC-365mfc) purificado, com um teor diminuído de cloreto de hidrogênio, fluoreto de hidrogênio ou contaminações insaturadas. Para esse fim, o material a ser purificado é tratado na fase líquida com um agente de adsorção inorgânico, sólido, ou moléculas biatómicas, que se adicionam a compostos múltiplos de C-C. Preferivelmente, trata-se o produto a ser purificado com flúor elementar. O teor de fluoreto de hidrogênio e cloreto de hidrogênio pode ser reduzido para abaixo de 1 ppm, o teor de compostos de (cloro)-flúor insaturados, para abaixo de 20 ppm e o teor de compostos de C2 insaturados, para abaixo de 10 ppm. Foi descoberto também que fluortri-cloroetileno pode ser usado como substância de controle no monitoramento da purificação de 1,1,1,3,3-pentafluorbutano.
