1- decyl-3 -methylimidazolium

A series of dinitrophenylated amino-acids was studied in biphasic systems based on 1-decyl-3-methylimidazolium tetrafluoroborate and l-hexyl-3-methylimidazolium tetrafluoroborate at slightly basic conditions fixed at 7.4 using sodium phosphate buffer (Rodriguez et al., 2007). Authors observed that amino-acids distribute preferentially to the ionic liquid phase according to the length of their chain.

Cocalia et al. have reported the extraction of Am(III) with dialkylphosphoric or dialkylphosphinic acids from aqueous solution to l-decyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide [265], Their results suggest that the extraction is quite similar to the behavior found for organic solvent systems. Further studies on actinoid extraction using ILs have been reported by Visser et al. [153],... 

Very few examples of imine hydrogenation in ionic liquids have been published so far. Giernoth et al. screened eight different ionic liquids (the cations were [BMIMJ+, l-decyl-3-methylimidazolium ([DMIM]" "), N-butyl-3-methylpyridinium ([BMPy]+) and N-decyl-3-methylpyridinium ([DMPy]" ) combined with the anions [Bp4] and [(CF3 S02)zN] ) and compared them with toluene as solvent in the hydrogenation of trimethylindolenine with the Ir-XYLIPHOS catalyst system (Scheme 5.3-12) [120]. 

Such a multidimensional risk analysis is especially suitable for the comparison of chemical substances with a common scope of application. Since the imidazoHum ILs under investigation are being used as alternatives for conventional organic solvents, a first screening risk comparison of two selected substances with the common solvent acetone is presented here as a preliminary example. The chosen substances are l-butyl-3-methylimidazolium tetrafluoroborate ([BMIM] [BFJ) and l-decyl-3-methylimidazoHum tetrafluoroborate ([DMIM] [BF4]), one for its abundance in organic synthesis literature, the other for its increased toxicity (see below). 

Awad et al. reported extensive studies on the various imidazolium salts and montmo-rillonites modified with these salts [37]. The imidazolium salts included l,2-dimethyl-3-propylimidazolium, l-butyl-2,3-dimethylimidazolium, 1 -decyl-2,3-dimethylimidazolium, l,2-dimethyl-3-hexadecylimidazolium, l,2-dimethyl-3-eicosylimidazolium, 1,2-dimethyl-3-ethylbenzene imidazolium, and l-ethyl-3-methylimidazolium. The authors investigated the effect of counterion, alkyl chain length, and structural isomerism on the thermal stability of the imidazolium salts and compared their behavior with that of the conventional quaternary ammonium ions using a number of characterization techniques. It was reported that... 

In the light of the foregoing discussion, it is expected that SAIL can alter the properties of calixarenes and their derivatives as it possesses favorable properties of both RTILs and surfactants. Thus, understanding the effect of SAIL on the properties of calixarenes with different molecular architecture can open up new avenues in the field of host-guest chemistry. We report herein the outcomes of the investigation of the effect of a SAIL, I-decyl-3-methylimidazolium chloride ([Cj mim][Cl]), on four structurally different calixarenes, (1), (2), (3), and (4), within basic aqueous media...

The fluorescence probe pyrene was purchased from Sigma-Aldrich in the highest purity possible and was recrystallized thrice before use. Spectroscopic-grade high-purity l-decyl-3-methylimidazolium chloride ([Cj(,mim][Cl], liquid at room temperature) and decyltrimethylammonium chloride (DeTACl, solid at room temperature) were purchased from Sigma-Aldrich in the highest purity possible and were stored under inert atmosphere.p-Nitrophenol and sodium hydroxide were purchased from...
