Abstract

"PROCESSO PARA PRODUçãO DE óXIDO DE PROPILENO". A presente invenção refere-se a um processo para produção de óxido de propileno, o qual compreende etapas descritas abaixo, no qual hidroperóxido de isopropilbenzeno alimentado a uma etapa de epoxidação não sofre uma história de calor, incluindo aquecimento sob uma temperatura não menor que a temperatura (t<198>C) representada pela equação seguinte (1), t (<198>C)=150 - 0,8 x W (1) W: teor (% em peso) de hidroperóxido de isopropilbenzeno em uma solução contendo hidroperóxido de isopropilbenzeno: etapa de oxidação: uma etapa em que isopropilbenzeno é oxidado para obter hidroperóxido de isopropilbenzeno, etapa de epoxidação: uma etapa em que hidroperóxido de isopropilbenzeno obtido na etapa de oxidação é reagido com propileno para obter óxido de propileno e álcool cumílico, e etapa de hidrogenólise: uma etapa em que álcool cumílico obtido na etapa de epoxidação é submetido à hidrogenólise para obter isopropilbenzeno, e esse isopropilbenzeno é reciclado à etapa de oxidação como uma matéria-prima para a etapa de oxidação.
