Abstract
<B>"PROCESSO DE FASE LìQUIDA PARA PRODUçãO DE ADUTOS DE ALCANO HALOGENADO E PROCESSO PARA PRODUçãO DE UM HIDROFLUOROALCANO"<D>. A presente invenção trata-se de um processo de fase líquida para a produção de adutos de alcano halogenado de fórmula CAR^ 1^R^2^CBR^ 3^R^ 4^ (na qual A, B, R^ 1^, R^ 2^, R^ 3^ E R^ 4^ são tal como definido no relatório descritivo), o qual envolve a colocação de um alcano halogenado correspondente, AB, em contato com uma olefina correspondente, CR^ 1^R^ 2^=CR^ 3^R^ 4^, em um solvente, e na presença de um sistema catalisador que contém (i) pelo menos um catalisador de cobre monovalente, e (ii) pelo menos um promotor iónico selecionado do grupo que consiste em haletos de amónio substituídos, haletos de piridínio e de piridínio substituído, e sais quaternários do tipo (MQ~ 4~)Y, onde M é um elemento do Grupo VA da Tabela Periódica (ou seja, N, P, As, Sb, ou Bi), Q é um grupo C~1~-C~ 18~ hidrocarbila, e Y é cloreto, brometo ou iodeto. A produção de hidrofluroalcanos através da reação de adutos selecionados do tipo produzido acima com HF também é descrita. O processo é operado em uma dinitrila ou um éster de carbonato cíclico como solvente o qual divide a mistura de reação em duas fases líquidas.
