Dear readers, I tied to dry
Bis(trifluoromethane)sulfonimide lithium salt (LiTFSI) in oven at 60°C and at P=0.19bar (corresponds to the point of evaporation of water) and It failed to dry the salt. I also read in a document provided by MTI ( http://www.mtixtl.com/tech-articles/EQ-Lib-LiTFSI_Application_Note_1.pdf ) that LiTFSI should be dried under vaccum at 120°C for 48h. I did the same, but eventually it didn't work and the salt became yellowish and not fully dry. For sure I noticed that the salt lost some water, but it is still wet (like a paste)... So any method on how to dry this salt (with some paper reference if there is)? Kindly.
First, you should select a good supplier to order LiTFSI. Second, dry at 80 -100 ⁰C under vacuum for a minimum of 12 hours. In my opinion, 0.19bar is not so high vacuum condition.
Regards.
