Abstract
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.
