Abstract

"PROCESSOS PARA A RETIRADA DE áGUA DE áCIDO CIANìDRICO POR DESTILAçãO E PARA A HIDROCIANAçãO DE OLEFINAS OU DIENOS". A invenção refere-se a um processo para a retirada de água de ácido cianídrico por destilação, que compreende a destilação de ácido cianídrico bruto contendo de 50 a 99,9% em peso de HCN, de 0,1 a 40% em peso de água, de 0 a 15% em peso de óxidos de carbono e opcionalmente de 0,01 a 1% em peso de um estabilizante não volátil, em uma pressão de 1 bar a 2,5 bar, uma temperatura de fundo de 100<198>C a 130<198>C e uma temperatura de topo de 25<198>C a 54<198>C, na ausência de um estabilizante volátil, em uma coluna de destilação para obter uma corrente de retirada de topo contendo ácido cianídrico anidro purificado e óxidos de carbono e uma corrente de retirada de fundo compreendendo água e, quando apropriado, o estabilizante não volátil.
