1. A process for the production of chlorinated propanes and/or propenes from a feedstream comprising 1,2-dichloropropane comprising catalyzing at least one chlorination step with one or more regioselective catalysts that provide a regioselectivity to one chloropropane of at least 5:1 relative to oth
1. A process for the production of chlorinated propanes and/or propenes from a feedstream comprising 1,2-dichloropropane comprising catalyzing at least one chlorination step with one or more regioselective catalysts that provide a regioselectivity to one chloropropane of at least 5:1 relative to other chloropropanes. 2. The process of claim 1, wherein the regioselective catalyst comprises aluminum chloride. 3. The process of claim 1, wherein the regioselective catalyst comprises a nonmetallic iodide, an inorganic iodine salt, or less than 10,000 ppm elemental iodine. 4. The process of claim 3, wherein the regioselective catalyst comprises a nonmetallic iodide comprising one or more iodobenzenes or halogenated iodobenzenes, phenylchloroiodonium chloride, diaryliodonium salts, iodinated polymers, iodoxy compounds, iodoso compounds, iodine mono- and trihalides, iodine oxides, and derivatives or combinations of any number of these. 5. The process of claim 3, wherein the regioselective catalyst comprises an inorganic iodine salt comprising sodium iodate, sodium periodate, or combinations of these. 6. The process of claim 1, wherein at least two chlorination steps are catalyzed with the regioselective catalyst. 7. The process of claim 6, wherein one chlorination step is catalyzed with aluminum chloride, and another step is catalyzed with a nonmetallic iodide, an inorganic iodine salt or less than 10,000 ppm elemental iodine. 8. The process of claim 7, wherein both steps are conducted in the same reactor. 9. The process of claim 1, wherein at least one chlorination step is conducted in the presence of a free radical initiator or ionic chlorination catalyst, wherein the free radical initiator comprises azobisisobutyronitrile, 1,1′-azobis(cyclohexanecarbonitrile), di-tert-butyl peroxide, benzoyl peroxide, dibenzoyl peroxide, methyl ethyl ketone peroxide, acetone peroxide, or a combination of any number of these. 10. The process of claim 1, further comprising at least one dehydrochlorination step. 11. The process of claim 10, wherein the at least one dehydrochlorination step is conducted in the presence of a catalyst. 12. The process of claim 1, wherein the source of chlorine atoms comprises either sulfuryl chloride, chlorine or a combination of these. 13. The process of claim 12, wherein the process is further conducted in the presence of a solvent comprising carbon tetrachloride and/or sulfuryl chloride. 14. The process of claim 1, wherein the one chloropropane is a tri-, or pentachloropropane comprising 1,1,2-trichloropropane, 1,1,2,2,3-pentachloropropane or a combination of these. 15. The process of claim 1, wherein the chlorinated propene comprises 1,1,2,3-tetrachloropropene. 16. The process of claim 1, wherein the chlorination step occurs at ambient pressure.
