Abstract
A process for treating a heavy byproduct stream from an initial chlorinated propane forming reaction in order to increase the final output of chlorinated propene and remove metal catalyst. In particular, the process disclosed herein provides for a primary stream in which chlorinated propanes are converted to chlorinated propenes in a catalytic dehydrochlorination reaction, while also treating a separate byproduct stream with a caustic to precipitate metal from a metal catalyst and convert any remaining chlorinated propanes to chlorinated propenes in order to increase final chlorinated propene output.
