A green and novel procedure for the preparation of ionic liquid

Spectroscopic and viscometric studies on the interaction of ionic liquid, 1-butyl-3-methylimidazolium bromide with polyvinyl pyrrolidone

“…The ionic liquid used in this study, 1-butyl-3-methylimidazolium bromide, [BMIm]Br, was synthesized and purified according to the procedures described in the literature [26][27][28][29]. In this synthesis, Nmethylimidazole, 1-bromobutane and ethylacetate were used.…”

Measurement and modeling of osmotic coefficients of aqueous solution of ionic liquids using vapor pressure osmometry method

“…[BMIm]BF 4 was prepared and purified by using the procedure described by Fang et al [37]. Briefly, N-methylimidazole, 1-bromobutane and sodium tetrafluoroborate were stirred in a three-necked flask with a reflux condenser at 353.15 K for 3.5 h. Upon completion of the reaction, the mixture was diluted with 50 mL of acetonitrile, after elimination of the precipitated salt (NaBr), the filtrate was then filtered through a pad of celite to remove the residual halide salt and finally concentrated by rotary evaporation to afford a colorless to pale yellow liquid with a yield of greater than 98%, without reaction with AgNO 3 aq.…”

Alkyl Thiophene Vinylene Electropolimerization in C<sub>8</sub>mimPF<sub>6</sub>, Potential Use in Solar Cells

“…The IL C 8 mimPF 6 was synthesized in one step without the use of solvents, according to the procedure described by Fang et al [22], which comprises reacting equimolar amounts of 1-methylimidazole (99%), 1-bromooctane (99%) and potassium hexafluorophosphate salt, KPF 6 (98%); all reactive were purchased from Aldrich.…”
