Dimethylformamide liquid temperature range

Temperature range of stability of imidazolium-based ILs (first four lines starting from the top of the figure) in comparison with that of several other liquid electrolyte solution (following five lines). BMI, l-butyl-3-methylimidazolium EMI, l-ethyl-3-methylimidazolium DMF, dimethylformamide. 

Dimethylformamido. Dimethylformamide (DMF) is a colorless, mobile liquid that is miscible with water. Its slight amine odor results form hydrolysis of the DMF by absorbed water to give dimethylamine and formic acid the purified solvent cannot be stored for more than a day or so at room temperature without some decomposition. DMF, with a dielectric constant of 37, is a good solvent for a wide range of organic compounds and it also will dissolve many... 

The homopolymer, prepared by polymerization in liquid ammonia with sodium initiator at-77 °C, is insoluble in acetone, but it is soluble in dimethylformamide. When it is formed with lithium in liquid ammonia, at -75 °C, the molecular weight of the product increases with monomer concentration and decreases with initiator concentration. If, however, potassium initiates the reaction rather than lithium, the molecular weight is independent of the monomer concentration. " " Polymethaciylonitrile prepared with n-butyllithium in toluene or in dioxane is crystalline and insoluble in solvents like acetone. When polymerized in petroleum ether with /i-butyllithium, methacrylonitrile forms a living polymer. Highly crystalline polymethacrylonitrile can also be prepared with beryllium and magnesium alkyls in toluene over a wide range of temperatures.
