Abstract

"PROCESSO PARA A PREPARAçãO DE 1,1,1,2-TETRAFLUOROETANO". Esta invenção refere-se a um processo para preparar um catalisador de Cr~ 2~O~ 3~/AI~ 2~O~ 3~ co-precipitado promovido por zinco, dito processo compreendendo co-precipitação de hidróxidos de metais de cromo e alumínio de soluções de sais de metais trivalentes correspem quentes usando NH~ 4~OH, NaOH ou KOH como uma base e seguido por calcinação para proporcionar pré-catalisador de óxido misto em forma amorfa a qual é impregnada com uma quantidade promotora de atividade de composto de Zinco. O catalisador é usado para a preparação de HFL-134a por fluoração de tricloroetileno e fluoração do produto intermediário pela reação formadora (HCFC-133A).
