Abstract

"PROCESSO PARA A EPOXIDAçãO DE OLEFINAS". A invenção aqui descrita refere-se a um processo para a epoxidação catalítica de olefinas com peróxido de hidrogênio em um sistema de reação de fluxo contínuo, onde a mistura de reação é passada através de um leito fixo de catalisador dentro de um reator equipado com meios de resfriamento enquanto mantendo um perfil de temperatura dentro do reator de modo que a temperatura de meio de resfriamento do meio de resfriamento seja pelo menos 40<198>C e a temperatura máxima dentro do leito de catalisador seja 60<198>C no máximo.
