    摘要： A method of preparing N,N-disubstituted-3,3′-dithiodipropionamide of formula (2) is provided. In the method, 3-mercaptopropionamide of formula (4) reacts with an aqueous solution of amine to prepare N-substituted-3-mercaptopropionamide of formula (3) and N-substituted-3-mercaptopropionamide reacts with an aqueous solution of hydrogen peroxide. In addition, a method of preparing substituted 3-isothiazolone is provided. In the method, the produced N,N-disubstituted-3,3′-dithiodipropionamide reacts with a halogenating agent, wherein X and Z are same or different and each selected from the group consisting of hydrogen or a lower alkyl group; Y is selected from the group consisting of hydrogen, an alkyl group of 1 to 18 carbon atoms, a cycloalkyl group of up to 10 carbon atoms, an aralkyl group of up to 10 carbon atoms, an aryl group of up to 10 carbon atoms, a halogen-, lower alkyl- or lower alkoxy-substituted aryl group, a cyano alkyl group, a carboalkoxyalkyl group, a haloalkyl group, an alkoxyalkyl group, an aryloxyalkyl group of up to 12 carbon atoms, an aralkoxyalkyl group of up to 12 carbon atoms, a dialkylaminoalkyl group, an alkylacyl group of up to 8 carbon atoms, a lower alkylsulfonyl group, an arylsulfonyl group of up to 10 carbon atoms, a cyano group and a carbamoyl group.
