Abstract

L'invention concerne un procédé continu pour la préparation, à l'échelle industrielle, d'oxyde de propylène à partir de peroxyde d'hydrogène et de propylène. Ce procédé comprend les états consistant à faire réagir une solution aqueuse d'un catalyseur hydrosoluble avec de l'acide propionique; à extraire au benzène; à concentrer, à traiter l'extrait avec de l'eau ; à faire réagir la solution avec du propylène en excès et à isoler l'oxyde de propylène. L'invention est applicable dans l'industrie chimique.
