Abstract

"PROCESSOS PARA PREPARAR óXIDO DE ALQUILENO E PARA PRODUZIR UM ALQUILBENZENO A PARTIR DE UM ALQUILFENIL áLCOOL". Processo para preparação de óxido de alquileno, o qual processo compreende: (i) oxidar um alquilbenzeno para obter uma corrente que compreende alquilbenzeno hidroperóxido; (ii) colocar em contato pelo menos uma parte do alquilbenzeno hidroperóxido obtido na etapa (i) com uma olefina para obter uma corrente de produto que compreende um óxido de alquileno; (iii) separar o composto óxido de alquileno da corrente de produto da etapa (ii) para obter (a) uma corrente de produto residual compreendendo alquilfenil álcool e (b) óxido de alquileno; (iv) alimentar pelo menos uma parte da corrente de produto residual compreendendo alquilfenil álcool a um reator que possui uma zona de destilação catalítica e, concomitantemente no reator: (a) colocar em contato a corrente de produto residual compreendendo alquilfenil álcool com hidrogênio na zona de destilação catalítica para converter o alquilfenil álcool na corrente de produto residual a alquilbenzeno e formar uma mistura de reação; e (b) separar o alquilbenzeno da mistura de reação por meio de uma destilação fracionada; (v) retirar uma corrente que compreende alquilbenzeno e que possui uma concentração de alquilfenil álcool mais reduzida que a corrente de alimentação do reator em uma posição acima da zona de reação catalítica; retirar do reator em uma posição mais baixa que a zona de destilação catalítica uma corrente de fundo que compreende dímero(s) de alquilbenzeno; alquilbenzeno; e (viii) reciclar pelo menos uma parte do alquilbenzeno produzido de (iv)(b) e/ou (vi) para a etapa (i).
