CA 2267330

Propylene is oxidized to propylene oxide in the vapor phase using oxygen and a supported catalyst comprising silver, gold, a potassium promoter such as potassium nitrate or potassium carbonate and a support comprised in whole or in substantial part of an alkaline earth metal carbonate.

La présente invention porte sur un procédé consistant à oxyder du propylène en phase gazeuse de manière à obtenir de l'oxyde de propylène, en utilisant de l'oxygène, un catalyseur sur support comprenant de l'argent, de l'or, un agent promoteur du potassium tel que le nitrate de potassium ou le carbonate de potassium, et un support constitué, en totalité ou pour une partie substantielle, d'un carbonate alcalin de métal terreux.
