摘要:
According to the method for fluorosulfate and the method for producing bis(fluorosulfonyl)imide onium salt, first, an aqueous solution is prepared by dissolving a mixed liquid containing bis(fluorosulfonyl)imide and fluorosulfonic acid in water. Then, the aqueous solution is neutralized with an alkaline compound, producing bis(fluorosulfonyl)imide salt and fluorosulfate. In the methods, fluorosulfate, and bis(fluorosulfonyl)imide onium salt can be obtained safely and easily.

摘要:
A process for producing a compound (I) which comprises the step of reacting a compound (II) with a base in an aprotic solvent as shown by the scheme: (II) (I) wherein R1 and R2 each independently represents lower alkyl.
wherein Ar 1 and Ar 2 independently represent a divalent aromatic groups, m represents an integer of 0 to 3, and X + represents an ion selected from hydrogen ion, an alkali metal ion and ammonium ion, which is excellent in proton conductivity, thermal resistance and strength. The polymer electrolyte is soluble in solvents and has excellent film forming property and recycling efficiency.

摘要:
The invention relates to a method for the safe production of nitroethionate, by reaction of 4-nitro-N-methylaniline with 1,3-dioxa-2,4-dithian-2,4-bis dioxide. The method is characterised in that an ether of polyhydric alcohols or a cyclic ether in a nitrile substituted hydrocarbon is chosen as solvent. The risk of localised overconcentration, localised overheating or explosions is avoided by a homogeneous reaction procedure.
