High impact information on 1-Butyl-3-methylimidazolium

The molar enthalpy of vaporization of 1-butyl-3-methylimidazolium dicyanamide, 157.2 +/- 1.1 kJ.mol-1, was obtained from the temperature dependence of the vapor pressure measured using the transpiration method [2].
Poly(1,2-butadiene-block-ethylene oxide) (PB-PEO) block copolymer micelles are found to partition reversibly between an ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIM][PF(6)]) and water, thereby functioning as micellar shuttles controlled simply by temperature [3].
In this article we explore in atomistic detail and explain in an intuitive way the peculiar volumetric behavior experimentally observed when supercritical CO2 is dissolved in 1-butyl-3-methylimidazolium hexafluorophosphate ([Bmim+] [PF6(-)]) [4].
Neutral allylic alkylation reactions, in which a base is generated in situ and which hence require no external bases, can significantly be retarded when carried out in the ionic liquid 1-butyl-3-methylimidazolium tetrafluoroborate ([bmim][BF(4)]) [5].
Thus, 1-butyl-3-methylimidazolium hexafluorophosphate and the analogous chloride salt can be used as stationary phases for gas chromatography (GC) [6].

An aqueous solution of ionic liquid BMIM.BF(4) (1-butyl-3-methylimidazolium tetrafluoroborate) was used as the reaction medium for the asymmetric hydrolysis of D,L-p-hydroxyphenylglycine methyl ester to enantiopure L-HPG (L-p-hydroxyphenylglycine) for the first time [8].
The molecular structure and rotational motion of the ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate ([BMIM][PF6]) were studied over a wide temperature range using the Bloembergen-Purcell-Pound 13C NMR spin-lattice relaxation method and NOE factors [9].
The effect of CO2 on the phase behavior of the reaction system and equilibrium conversion for esterification of acetic acid and ethanol in ionic liquid (1-butyl-3-methylimidazolium hydrogen sulfate, [bmim][HSO4]) was studied at 60.0 degrees C up to 15 MPa [10].

Anatomical context of 1-Butyl-3-methylimidazolium

Microemulsion electrokinetic chromatography (MEEKC) using 1-butyl-3-methylimidazolium tetrafluoroborate (BMIM-BF(4)) ionic liquid (IL) as additive was developed for the analysis of baicalin, wogonin and baicalein in Scutellariae radix and its preparation [14].
Uptake kinetics of naphthalene, 1-methylnaphthalene, phenanthrene, pyrene, chrysene by layflat low-density polyethylene tubing (15 cm x 2 cm) filled with 0.5 ml 1-butyl-3-methylimidazolium hexafluorophosphate ionic liquid were studied in a laboratory continuous-flow system for the duration of 16 days [15].
Of all the approaches tried, enzyme precipitated and rinsed with n-propanol (EPRP) gave the best results (about 10,000 times increase in initial rates in 1-butyl-3-methylimidazolium hexafluorophosphate ([Bmim][PF(6)]) over what is obtained with pH tuned lyophilized powders) [16].

Gene context of 1-Butyl-3-methylimidazolium

Sum frequency generation spectroscopy, SFG, was used for the surface characterization at the gas-liquid interface of the 1-butyl-3-methylimidazolium cation combined with the following anions: Br-, I-, PF6-, BF4-, (CF3SO2)2N- (imide), SCN-, CH3SO3- (MeSO3), CH3SO4- (MS), and (CN)2N- (DCN) [17].

Analytical, diagnostic and therapeutic context of 1-Butyl-3-methylimidazolium

Use of the ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate in countercurrent chromatography [18].
Shock-induced crystallization of the supercooled ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate, C(8)H(15)N(2)(+) x PF(6)(-), allows for the first time precise X-ray diffraction analysis directly pertinent to the fluid state [19].
