Abstract

"PROCESSO PARA A EPOXIDAçãO DE OLEFINAS". A presente invenção refere-se a um processo para a epoxidação catalítica de olefinas na presença de um catalisador de zeólito que contém titânio e um solvente polar, por meio do que a desativação do catalisador durante a reciclagem do solvente é consideravelmente reduzida. No processo, um ou mais compostos que contêm nitrogênio são introduzidos em algum estágio, uma corrente de solvente é recuperada, tratada de modo a conter menos de 50 pppm de nitrogênio na forma de compostos orgânicos de nitrogênio, e pelo menos uma parte dela é reciclada à etapa de epoxidação. A invenção é também direcionada a um processo para a epoxidação catalítica de propeno que integra o tratamento inventivo e reciclagem do solvente no processamento da mistura reacional.
