Claims112
Process for reducing a halogenated organic compound having at least one carbon-halogen group in such manner as to remove halogen from said compound, comprising:
- treating said compound with ultraviolet radiation in the range of about 1800 to 4000A and hydrogen in the absence of any substantial amount of oxidizing agent.
Process for degrading a halogenated organic compound having at least one carbon-halogen group in such manner as to remove halogen from said compound, said compound being of the type which forms alkali metal salts when treated with an aqueous alkaline solution containing sodium or potassium ions, comprising, dissolving said compound in a solvent comprising an aqueous alkaline solution containing sodium and/or potassium ions, said solution being substantially free from organic solvent, with ultraviolet radiation in the range of about 1800 to 4000A substantially in the absence of other compound treating agent.
Process for degrading a halogenated organic compound having at least one carbon-halogen group in such manner as to remove halogen from said compound, comprising:
- treating an alkaline liquid solution of said compound with ultraviolet radiation in the range of about 1800 to 4000 A and hydrogen in the absence of any substantial amount of oxidizing agent.
