Abstract: Processes for the production of chlorinated propenes are provided. The present processes make use of 1,2-dichloropropane, a by-product in the production of chlorohydrin, as a low cost starting material, alone or in combination with 1,2,3-trichloropropane. At least one chlorination step is conducted in the gas phase. The present processes can also generate anhydrous HCI as a byproduct that can be removed from the process and used as a feedstock for other processes, providing further time and cost savings.

Abstract: Methods and assemblies for improving the reaction kinetics of, conserving reactants utilized in, and/or producing a more pure reaction product of, liquid-phase reactions that involve volatile reactants and products are provided. The methods and assemblies herein provide for a feed of reaction liquid to two or more absorption zones, wherein the temperature and/or feed rate of the liquid is independently adjusted prior to introduction into at least one of the two or more absorption zones. More particularly, the temperature and feed rate of the liquid as delivered to each absorption zone can be adjusted independently to optimize the absorption of at least a portion of any gaseous reactants and byproducts from the gaseous product stream and/or to optimize reaction zone conditions. Reaction kinetics may thus be improved, or substantially maintained.
