Ionic liquids with (2-bromoethyl)trimethylammonium, (3-bromopropyl)trimethylammonium and (2-bromoethyl)diethylammonium cation and method for obtaining them
Ionic liquids with (2-bromoethyl)trimethylammonium, (3-bromopropyl)trimethylammonium and (2-bromoethyl)diethylammonium cation and method for obtaining them
the subject of ionic liquids are of anionem bis (trifluorometylosulfonylo) imidkowym and kationem (2 - bromoetylo) trimetyloamoniowym of general formula 1 or (3 - bromopropylo) trimetyloamoniowym of general formula 2, or (2 bromoetylo) dietyloamoniowym of general formula 3, as applicable electrolytes for electrochemical capacitors.the subject application is the way they receive, which is that bromide (2 - bromoetylo) trimethylammonium chloride with general formula or (3 - bromopropylo) trimethylammonium chloride with general formula, or (2 bromoetylo) dimethylammonium of general formula dissolves in water, mixed with a sol and soda, or potasowu0105, or lithium.bis (trifluorometylosulfonylo) imidku dissolved in water in a mole ratio of 1: amoniowego bromide salt from 0.95 to 1: 1.05, preferably 1: 1, at a temperature from 293 k to 363, favourably 293 k, during at least 2 minutes, then separates the reaction product in the form of a second phase that turn well soluble in ester kru00f3tkou0142au0144cuchowym, preferably ethyl acetate, washed several times with water.after the solvent vaporized under a reduced pressure and the product dried.
