Action du monoxyde d'azote sur le trichloréthylène et sur le tétrachloréthylène

The Action of Nitrogen Monoxide on Trichloro‐and Tetrachlor‐Ethylene . Under the sun light and at room temperature nitric oxide reacts with trichlorethylene and tetrachlorethylene giving monomer nitroso nitrated compounds. These compounds can also be obtained through reaction of dinitrogen trioxide with trichlorethylene and tetrachlorethylene. The nitrating and oxidizing properties of nitric oxide can be considered through these reactions: – Trichlorethylene leads to: pentachlorethane,1,1,1,2‐tetrachlor‐2‐nitroethane, dichloracetic acid and 1,1,3,3‐4‐pentachloro‐4‐nitro‐1‐butene: CO 2 and CO are also observed. –Tetrachlorocthylene gives : hexachlorethane, tetrachloro‐2pentaclorethyl‐1,2‐oxazetidine; carbon tetrachlorid and trichloracetylchlorid arc obtainetl in very little yiclcl. These results prove that oxidizing cleavage may occur. Kitric oxitl reacts giving nitrogen as main gazcous product, prouved by gas liquid chrornatography.
