Abstract
The present invention provides an industrially advantageous method for producing bis (halosulfonyl) amine that makes it possible to inhibit the rapid generation of gas and reduce the amount of halogenating agent used by controlling the reaction rate among sulfamic acid, the halogenating agent and a halosulfonic acid to nearly a constant rate from the initial stage to the final stage of the reaction. The method for producing bis (halosulfonyl)amine of the present invention allows the obtaining of a bis (halosulfonyl) amine such as N-(fluorosulfonyl)-N-(chlorosulfonyl) amine or bis (chlorosulfonyl) amine by a production method that includes heating a mixture containing sulfamic acid and a halosulfonic acid to a temperature higher than room temperature, adding a halogenating agent thereto, and allowing to react while adjusting to a prescribed temperature.

Problems to be Solved by the Invention
[0006]
Heating to a temperature of 80 C is required to complete the reaction among sulfamic acid, thionyl chloride and chlorosulfonic acid. The boiling point of thionyl chloride used as a chlorinating agent is 76 C. If the temperature of a mixture containing thionyl chloride is raised to 80 C or higher, the thionyl chloride evaporates and is eliminated from the reaction system in the form of thionyl chloride. Consequently it is necessary to add an excess of thionyl chloride to the reaction system. Therefore, a method has been attempted that consists of lowering the temperature early in the reaction and raising the temperature late in the reaction. According to this method, although the loss of thionyl chloride is reduced, since a large amount of gas may be generated rapidly such as when switching from the initial reaction temperature to the final reaction temperature, this method was unsuitable for use as an industrial production method.

As can be understood from the reaction schemes, when 1 mole of sulfamic acid, 1 mole of halosulfonic acid and 2 moles of halogenating agent in the form of thionyl chloride react, 2 moles of sulfurous acid gas (SO2) and 3 moles of hydrochloric acid gas (HC1) are formed. If the sulfamic acid, halogenating agent (thionyl chloride) and halosulfonic acid are mixed and allowed to react by heating the mixture to raise the temperature, the reaction rate becomes excessively fast and sulfurous acid gas and hydrochloric acid gas are generated rapidly, thereby resulting in problems such as the pressure of the reactor becoming excessively high.
In contrast, according to the method of the present invention, rapid generation of gas is inhibited by controlling the reaction rate among the sulfamic acid, halogenating agent and halosulfonic acid to nearly a constant rate from the initial stage to the final stage of the reaction.
