titleOfInvention | New process for bistrifluorosulfonylimide salt |
abstract | The present invention provides a method for preparing a bistrifluorosulfonylimide salt, wherein the corresponding N-alkyl substituted bistrifluoromethanesulfonylimide is prepared using a primary amine and trifluoromethanesulfonic anhydride. Step S1 and; Step S2 of obtaining a crude product by reacting N-alkyl-substituted bistrifluoromethanesulfonylimide with a salt; And a step S3 of obtaining a bistrifluoromethanesulfonylimide salt by crystallization and vacuum-drying the crude product. The present invention has the following advantageous effects. N-alkyl-substituted bistrifluoromethanesulfonylimide has stable properties, does not produce corrosive substances in the entire reaction, and is suitable for large-scale production because it has less wastewater, waste gas and waste. A trifluoromethanesulfonylimide salt can be obtained, and thus has a relatively large practical value and socio-economic effect. |
