摘要： The present invention provides a method for producing a disulfonylamine alkali metal salt, including a step of subjecting a disulfonylamine onium salt represented by formula [I] (wherein each of R 1 and R 2 independently represents a fluorine atom or a fluorinated alkyl group having 1 to 6 carbon atoms, provided that at least one of R 1 and R 2 represents a fluorine atom, and each of R 3 , R 4 , R 5 and R 6 independently represents a hydrogen atom or the like) to a cation exchange reaction in an organic solvent, thereby producing a disulfonylamine alkali metal salt represented by formula [II] (wherein M + represents an alkali metal cation, and R 1 and R 2 are as defined in formula [I]), and a step of filtering the organic solvent solution containing the disulfonylamine alkali metal salt through a filter having a particle retention size of 0.1 to 10 µm to obtain a filtrate.

摘要： The present invention provides a polydialkylsilane, and a method for producing a polydialkylsilane, including a step of adding a compound represented by formula (I) (in formula (I). R 1 and R 2 independently represent an alkyl group, and X 1 and X 2 independently represent a halogen atom) to an organic solvent containing an alkali metal, in which 0.010 [hr -1 ] ‰¤ the average addition rate of compound (I) [moles·hr -1 ]/the amount of the alkali metal [moles] ‰¤ 0.055 [hr -1 ].
