Abstract
Processes for the production of chlorinated alkanes are provided. The present processes comprise catalyzing the chlorination of a feedstream comprising one or more alkanes and/or alkenes with a catalyst system comprising one or more inorganic iodine salts and/or lower than conventional levels of elemental iodine and at least one Lewis acid. The processes are conducted in a nonaqueous media, and so, the one or more inorganic iodine salts are recoverable and/or reusable, in whole or in part.
Claims17
A process for the production of chlorinated propanes comprising, in a nonaqueous media, catalyzing the chlorination of a feedstream comprising one or more propanes with a mixed catalyst system comprising at least one Lewis acid selected from the group consisting of ferric chloride, antimony pentafluoride, boron trichloride, aluminum trichloride, stannic chloride or combinations of these, and one or more inorganic iodine salts, wherein the process produces one pentachloropropane at a regioselectivity of greater than 10:1 over other pentachloropropane products;
- and wherein the source of chlorine atoms comprises chlorine gas, sulfuryl chloride or a combination of these.
A process for the production of a product comprising a pentachloropropane, the process comprising treating a feedstream comprising propanes, with a Lewis acid catalyst, a chlorine source, and one or more inorganic iodine salts, in a nonaqueous solvent, wherein the Lewis acid is selected from the group consisting of ferric chloride, antimony pentafluoride, boron trichloride, aluminum trichloride, stannic chloride and a combination thereof;
- the chlorine source is Cl2, SO2Cl2, or a mixture thereof, and the one or more inorganic iodine salts that are selected from the group consisting of sodium iodate, silver iodate, calcium iodate, potassium iodate, iodic acid, sodium periodate, potassium periodate, barium periodate, and periodic acid.
