Abstract

"PROCESSO PARA A SEPARAçãO DESTILATIVA DE ISÈMEROS DE PENTENO NITRILA". Processo para a separação destilativa de isómeros de penteno nitrila, que apresentam uma volatilidade relativa alfa na faixa de 1,0 a 1,3 em uma faixa de pressão de 1-500 kPa, caracterizado pelo fato de que a destilação é executada na presença de um diluente líquido, que forma azeótropos com os isómeros de penteno nitrila sob as mesmas condições de pressão, cuja volatilidade relativa alfa é mais alta do que a dos isómeros de penteno nitrila a serem separados.
