Method of converting a brominated hydrocarbon to a chlorinated hydrocarbon

A method of converting a brominated hydrocarbon to a chlorinated hydrocarbon comprising:

• (a) providing a feed stream comprising said brominated hydrocarbon, wherein said brominated hydrocarbon comprises at least one replaceable bromo group, wherein each replaceable bromo group is independently covalently bonded to an sp3 hybridized carbon;
• (b) providing a first fixed bed vessel comprising a first fixed bed comprising an ion exchange resin comprising chloride groups, wherein said ion exchange resin comprises water in an amount of less than or equal to 30 percent by weight, based on the total weight of said ion exchange resin and water;
• (c) introducing said feed stream into said first fixed bed vessel, and contacting together within said first fixed bed vessel said brominated hydrocarbon and said ion exchange resin, thereby replacing at least one replaceable bromo group of said brominated hydrocarbon with a chloro group, and converting at least a portion of said brominated hydrocarbon to said chlorinated hydrocarbon;
• and
• (d) withdrawing a product stream from said first fixed bed vessel, wherein said product stream comprises said chlorinated hydrocarbon.

A method of forming a dried ion exchange resin comprising:

• (a) providing a fixed bed vessel comprising a fixed bed comprising a wet ion exchange resin, wherein said wet ion exchange resin comprises a first amount of water;
• (b) contacting together, within said fixed bed vessel, said wet ion exchange resin and a heated hydrocarbon vapor that forms an azeotrope with water of said wet ion exchange resin, thereby forming a wet vapor comprising hydrocarbon vapor and water vapor;
• and
• (c) removing said wet vapor from said fixed bed vessel, thereby forming said dried ion exchange resin comprising a second amount of water, wherein said second amount of water is less than said first amount of water.
