    • The present invention provides a process that enables a substituted methylamine compound which is useful as an intermediate for the production of agricultural chemicals and medicines, to be produced easily, with good yield, and at low cost, and also provides a production intermediate thereof. The process comprises a step of reacting a hexamethylenetetraammonium salt compound represented by a formula (I) with a base to obtain an N-methylidene-substituted methylamine oligomer represented by a formula (II) or a mixture of two or more of the oligomers, and a step of hydrolyzing the N-methylidene-substituted methylamine oligomer represented by formula (II) or the mixture of two or more of the oligomers in the presence of an acid. (wherein A represents an organic group that is either a hydrocarbon group or a heterocyclic group, or said organic group that has a substituent, R represents a hydrogen atom, an organic group that is either a hydrocarbon group or a heterocyclic group, or said organic group that has a substituent, L represents a halogen atom and the like, and n represents an integer of 2 to 20)
    • 本发明提供了能够容易地以良好的产率,低成本地制造可用作农药和药品的中间体的取代甲胺化合物的方法,并且还提供其制备中间体。 该方法包括使由式(I)表示的六亚甲基四铵盐化合物与碱反应以获得由式(II)表示的N-亚甲基取代的甲基胺低聚物或两种或更多种低聚物的混合物的步骤,以及 在酸存在下水解由式(II)表示的N-亚甲基取代的甲胺低聚物或两种或更多种低聚物的混合物的步骤。 (其中A表示烃基或杂环基的有机基团或具有取代基的有机基团,R表示氢原子,作为烃基或杂环基的有机基团或所述有机基团 具有取代基的基团,L表示卤素原子等,n表示2〜20的整数)

    • A method for producing chlorosulfonyl isocyanate by reaction of sulfur trioxide with cyanogen chloride, wherein chlorosulfonyl isocyanate or a solution including chlorosulfonyl isocyanate is used as a reaction solvent, sulfur trioxide and cyanogen chloride which are respectively diluted with the chlorosulfonyl isocyanate or the solution including chlorosulfonyl isocyanate are added at the same time to a reaction system in an almost equimolar amount under reflux. By the production method of present invention, chlorosulfonyl isocyanate can be produced from sulfur trioxide and cyanogen chloride in which the yield of the chlorosulfonyl isocyanate is high, the method has excellent operability, number of equipments is reduced, and time for controlling the temperature is saved.
