PHOTOINITIATION OF SULFOCHLORIMATION OR SULFOOXYDATIN OF ALKANES BY UV EXCIMER RADIATION FOR PRODUCTION OF ALKANESULFOCHLORIDES AND ALKANESULFONATES

摘要

PROBLEM TO BE SOLVED: To provide a method for producing an alkanesulfochloride or an alkanesulfonate by reacting alkanes with SO2 and Cl2 or O2. SOLUTION: The above photoinitiation reaction is carried out by UV excimer radiation. Proper wavelength for UV excimer radiation is 150 nm to 470 nm. It is preferably to use the wavelengths (excimer) of 172 nm (Xe2*), 193 nm (ArF*), 222 nm (KrCl*), 248 nm (KrF*), 282 nm (XeBr*), 291 nm (Br2*), 308 nm (XeCl*), 342 nm (I2*) and 351 nm (XeF*).
