PROBLEM TO BE SOLVED: To provide a method for industrially and continuously producing an alkanesulfonyl chloride with high purity in high yield without by-producing a main chain-chlorinated product. SOLUTION: This for producing the alkanesulfonyl chloride by reacting a mercaptan or a disulfide with chlorine uses a loop-shaped reactor with an ejector. The alkanesulfonyl chloride is continuously formed by feeding the mercaptan or the disulfide to an aqueous solvent before entering the ejector while feeding the aqueous solvent to the reactor and circulating the aqueous solvent, to disperse or dissolve the mercaptan or the disulfide, and blowing chlorine gas from a sucking part of the ejector to react them. As a result, the alkanesulfonyl chloride is continuously produced without by-producing the main chain-chlorinated product. COPYRIGHT: (C)2004,JPO
