Abstract

Patente de Invenção <B>"PROCESSO DE EPOXIDAçãO USANDO-SE UM COMPOSTO DE PEROXOTUNGSTATO ESTABILIZADO COM FOSFATO COMO CATALISADOR"<D> Olefinas são convertidas de maneira seletiva em epóxidos, usando peróxido de hidrogênio como oxidante, em um sistema de reação em fase líquida única, caracterizado por uma fase líquida compreendendo, predominantemente, um solvente orgânico. A reação é catalisada por um composto que compreende uma espécie de peroxotungstato estabilizada com fosfato tendo uma razão atómica W:P de 2:1.
