Abstract

"CATALISADORES PARA A OXICLORAçãO DE ETILENO A 1,2-DICLOROETANO, E, MéTODOS PARA A PREPARAçãO DOS CATALISADORES E PARA A OXICLORAçãO DE ETILENO A 1,2-DICLOROETANO". Catalisadores para a oxicloração de etileno a 1,2-dicloroetano, que compreendem compostos de cobre e de magnésio suportados sobre gama alumina, em que o cobre, expresso como metal, está presente em uma quantidade de 7 a 12% em peso e a razão de Mg/Cu é desde 0,05 até 1, caracterizados pelo fato de que a distribuição de cobre na partícula de catalisador é tal que a razão de X/Y entre a concentração dos átomos de cobre sobre a superfície fornecida pela razão de A1/Cu (X) sobre a superfície (camada de 20-30 nm) e a concentração fornecida pela razão de A1/Cu (Y) em relação à partícula inteira é maior do 1,3 e pode atingir 3.
