Abstract
The key intermediate N,N′-dimethy1-3,3′-dithodipropionamide for preparing isothiazolone was synthesized starting from methyl acrylate by nucleophilic addition,purification with desulfurization and amidating,the total yield reached 85%.The effects of reaction agent relative ratio,reaction temperature and reaction time on the yield were discussed
