Abstract

Patente de Invenção: <B>"PROCESSO PARA A PURIFICAçãO DE BUTANO-1,4-DIOL"<D>. A invenção proporciona um processo para a purificação de alimentação de butano-1,4-diol contendo uma pequena quantidade de acetal cíclico, 2-(4'-hidroxibutóxi)-tetraidrofurano, o qual compreende a hidrogenação da alimentação de butano-1,4-diol em uma zona de hidrogenação na presença de uma quantidade menor de água e de um catalisador de hidrogenação, e recuperação da zona de hidrogenação de um produto de butano-1,4-diol que possui um teor reduzido de 2-(4'hidroxibutóxi)-tetraidrofurano, comparado com a alimentação de butano-1,4-diol.
