Lithium-glyme solvate ionic liquids (Li-G SILs) and super-concentrated electrolyte solutions (SCESs) are expected as a promising electrolyte for the next generation lithium secondary batteries. The former consists of only the oligoether glyme solvated lithium ion and its counter anion and the latter contains no full solvated Li+ ion by the solvents due to the extremely high Li salt concentration Although both of them are similar with each other, it is still unclear that both should be room-temperature ionic liquids (RTILs). To reveal the distinct definition for them, speciation analyses were performed to the Li-G SIL and the aqueous SCES to evaluate the free solvent concentration in these solutions with a new Raman/IR spectral anal. technique called complementary least square anal. (CLSA). Furthermore, from a thermodn. point of views, we investigated the solvent activity/activity coefficient in the gas phase equilibrated with sample solutions and found they can be a good criterion for SILs. In the experiment, the researchers used many compounds, for example, 2,5,8,11-Tetraoxadodecane (cas: 112-49-2HPLC of Formula: 112-49-2).
2,5,8,11-Tetraoxadodecane (cas: 112-49-2) belongs to ethers. Of all the functional groups, ethers are the least reactive ones. Ether bonds are quite stable towards bases, oxidizing agents and reducing agents. But on the other hand, ethers undergo cleavage by reaction with acids. Ethyl ether is an excellent solvent for extractions and for a wide variety of chemical reactions. It is also used as a volatile starting fluid for diesel engines and gasoline engines in cold weather. Dimethyl ether is used as a spray propellant and refrigerant. Methyl t-butyl ether (MTBE) is a gasoline additive that boosts the octane number and reduces the amount of nitrogen-oxide pollutants in the exhaust. The ethers of ethylene glycol are used as solvents and plasticizers.HPLC of Formula: 112-49-2
