Abstract
Macroporous, strong-acid polysiloxane ion exchange resins which have been converted to the silver or mercury form are utilized to remove iodides from non-aqueous organic media. In a particularly preferred method, hexyl iodide is removed from acetic acid.
Claims9
A method for removing iodide compounds from a non-aqueous organic medium comprising contacting the medium containing said iodide compounds with a macroporous, strong-acid, polysiloxane ion exchange resin wherein the macropores have a pore volume of from about 1 to about 3 ml/gram and a pore size in the range of from about 5 to about 100 nanometers and where at least 1 percent of the cationic ion exchange sites of the resin have been converted to the silver or mercury form.
