Abstract

<B>Patente de Invenção "PROCESSO DE EPOXIDAçãO USANDO CATALISADORES DE PRATA SUPORTADOS PRé-TRATADOS COM CLORETO ORGANICO"<D> Um processo de epoxidação de propileno, em que um catalisador de prata suportado é utilizado, pode ser operado em eficiência elevada, mesmo na ausência de qualquer cloreto orgânico na corrente de alimentação, contanto que o catalisador seja, primeiro, colocado em contato, em uma temperatura elevada, com uma corrente de tratamento, que compreende um cloreto orgânico e oxigênio molecular.
