| titleOfInvention | Synthetic method of piperazine film-forming ionic liquid |
| abstract | A method for synthesizing piperazine-based film-forming ionic liquids belongs to the field of compound synthesis, and includes: A. preparing acetylene chlorosulfonate or vinyl chlorosulfonate; B. adding ethylene glycol monomethyl ether, N,N-diisopropylethylamine and dichloroethane were added dropwise with methanesulfonyl chloride at 0°C under temperature control to prepare a reddish-brown liquid product; C, under nitrogen, add sodium and dichloroethane, and heat to sodium Melt, stir to room temperature, add N,N-dimethylethanolamine dropwise under temperature control at 0°C, react at room temperature, add reddish-brown liquid product at temperature control at 0°C, and react at room temperature to prepare liquid product; D, under nitrogen conditions, put in the container Add solvent, piperazine and liquid product, cool down to 0°C, add dropwise a mixture of methanesulfonyl chloride and acetylene chlorosulfonate, or add dropwise acetylene chlorosulfonate, or dropwise add vinyl chlorosulfonate, or dropwise add chlorine The mixture of vinyl sulfonate and methanesulfonyl chloride is reacted to prepare the corresponding piperazine film-forming ionic liquid. This method has high product yield and purity. |
