Patent

CA 2261269

Processes are disclosed for the conversion of propylene to methylmercaptopropanal by converting propylene to acrolein and converting acrolein to methylmercaptopropanal. The processes utilize oxygen and recycle propane to the acrolein reactor. Process feeds can comprise propane, propylene or mixtures thereof. The presence of propane in the propylene-to-acrolein reaction can enhance the efficiency of the processes.

L'invention concerne des procédés de conversion de propylène en méthylmercaptopropanal par conversion de propylène en acroléine et conversion d'acroléine en méthylmercaptopropanal. Les procédés utilisent de l'oxygène et recyclent du propane dans le réacteur d'acroléine. Les charges de traitement peuvent comprendre du propane, du propylène ou des mélanges de ceux-ci. La présence de propane dans la réaction propylène en acroléine peut améliorer le rendement des procédés.
