    摘要: A method for producing a 1,2-benzisothiazole characterized by treating a 2-(alkylthio)benzaldehyde oxime with a halogen compound; a method for producing a 3-halo-1,2-benzisothiazole characterized by treating a 1,2-benzisothiazole with a halogenating agent; and a method for producing a 1-(1,2-benzisothiazol-3-yl)piperazine characterized by reacting the obtained 3-halo-1,2-benzisothiazoles with a piperazine. By the method of the present invention, 1,2-benzisothiazoles and 3-halo-1,2-benzisothiazoles, which are useful as intermediates for pharmaceutical compositions such as psychotropic agents, and 1-(1,2-benzisothiazole-3-yl)piperazines synthesized therefrom can be obtained in a high yield without using expensive starting materials by shorter and simpler process than conventional methods.

    摘要: A process for producing a hydrogenated NBR latex wherein the latex particles have each a sufficiently small diameter and which has a sufficient quiescence stability without using any harmful solvent and restricting the type of the emulsifying agent. The production process comprises mixing an organic phase containing hydrogenated NBR dissolved in an organic solvent with an aqueous phase containing an emulsifying agent dissolved in water to effect emulsification and then distilling off the solvent, and is characterized by effecting the emulsification in the presence of an alcohol.
