| titleOfInvention | A method and device for preparing lithium trifluoromethanesulfonate |
| abstract | The invention relates to a method and a device for preparing lithium trifluoromethanesulfonate. The device provided by the invention includes a raw material storage tank, a reactor, a reflux device, a gas disperser and a drying device. The method of the present invention comprises: adding raw material lithium carbonate and organic solvent butanone into the reactor, after controlling the reflux temperature and the temperature of the reactor, adding trifluoromethanesulfonyl chloride into the reactor from the bottom of the reactor, and vaporizing the trifluoromethanesulfonyl chloride After passing through the gas disperser, it reacts with lithium carbonate, and the carbon dioxide generated by the reaction is discharged. The generated lithium trifluoromethanesulfonyl solution is filtered and then enters the drying device, and the lithium trifluoromethanesulfonate product is obtained after drying. The invention has the advantages of simple process, less required equipment, easy operation and high safety, effectively improves the purity of the product, and can meet the high purity requirement of the lithium battery industry. |
