Abstract

"PROCESSOS PARA A PREPARAçãO DE óXIDO DE ALQUILENO, E DE óXIDO DE PROPILENO". Processo para a preparação de óxido de alquileno, o qual processo compreende (i) misturar uma alimentação fresca, contendo hidroperóxido orgânico e alqueno, com uma corrente de reciclo, para obter uma mistura de reação contendo de 5 a 80 % em peso de álcool, com base na quantidade total da mistura de reação, (ii) colocar em contato a mistura de reação com um catalisador de epoxidação heterogêneo para obter uma corrente contendo óxido de alquileno e álcool, e (iii) reciclar de 30 a 95 % em peso da corrente obtida na etapa (ii) para a etapa (i).
