PRODUCTION OF METHANESULFONYL CHLORIDE

PURPOSE:To obtain methanesulfonyl chloride useful as a raw material for various industrial drugs, etc., inexpensively and easily in high yield while suppressing side effects, by irradiating a mixed gas of methane, a surfurous acid gas, and chlorine with light rays. CONSTITUTION:A mixed gas of 1-5mol...

Zusammenfassung:	PURPOSE:To obtain methanesulfonyl chloride useful as a raw material for various industrial drugs, etc., inexpensively and easily in high yield while suppressing side effects, by irradiating a mixed gas of methane, a surfurous acid gas, and chlorine with light rays. CONSTITUTION:A mixed gas of 1-5mols, preferably 1.1-2mols methane, 1-5mols, preferably 1.1-3mols sulfurous acid gas, and 1mol chlorine is irradiated with light rays at 200-600nm wavelength using a low-pressure mercury vapor lamp, a high-pressure mercury vapor lamp, various fluorescent tubes, a xenon lamp, and/or sunlight, to give the aimed substance. The reaction gas during light irradiation is kept at -10-100 deg.C, preferably at 0-30 deg.C, and an inexpensive natural gas and/or town gas can be used instead of methane.
