Abstract

Viene descritto un processo per la separazione di catalizzatori metallici a base di fosfotungstati di ammonio e fosfonio da miscele di reazione in cui sono disciolti. Il processo è basato sull'impiego di membrane semipermeabili ed ha trovato utile applicazione nella separazione dei suddetti catalizzatori da miscele ottenute dalla epossidazione di alcheni e dell'olio di soia.
