Abstract
método para separar acetonitrila de água, e, processo altamento integrado para a preparação de óxido de propileno um método para separar acetonitrila de água, compreendendo: (i) prover uma corrente s1 contendo pelo menos 95% em peso com base no peso total de s1, de acetontrila e água, em que a razão em peso de acetonitrila: água é maior do que 1; (ii) adicionar uma corrente p, que compreende pelo menos 95%, em peso, de c3, com base no peso total da corrente p, a s1, de um modo a que seja obtida uma corrente mista s2, c3 sendo propeno opcionalmente misturado com propano, com uma razão em peso mínima de propeno: propano de 7:3; (ii) submetendo-se s2 a uma temperatura de 92ºc no máximo, e a uma pressão de pelo menos 10 bar, obtendo-se uma primeira fase l1, que consiste essencialmente de c3, acetonitrila e água, e uma segunda fase líquida 12, que consiste essencialmente de água e acetonitrila, em que a razão em peso de acetonitrila: água em l2 é menor do que 1; (iv) e separando l1 de l2.
