Preparing method of high-purity imidazole acetate ionic liquid

The invention belongs to the technical field of ionic liquid synthesis, and particularly relates to a preparing method of high-purity imidazole acetate ionic liquid. The method includes the steps of making a 1-alkyl-3-methylimidazole halogenated product react with lithium perchlorate to obtain a high-purity 1-alkyl-3-methylimidazole perchlorate ionic liquid intermediate, and then conducting replacement reaction on the intermediate and potassium acetate or ammonium acetate to obtain the 1-alkyl-3-methylimidazole acetate ionic liquid. The raw materials are low in price and easy to obtain, the raw materials or middle byproducts are free of heavy metals or other pollutions, reaction is thorough, the reaction yield is 90.0% or above, the product purity is 99.0% or above, the content of halogenresidues in the product is smaller than or equal to 5 ppm, and the content of K ions or ammonium radicals in the product is 200 ppm or below.

Thermodynamic and molecular origin of interfacial rate enhancements and endo -selectivities of a Diels-Alder reaction

Organic reactions in general display large rate accelerations when performed under interfacial conditions, such as on water or at ionic liquid interfaces. However, a clear picture of the physicochemical factors responsible for this large rate enhancements is not available. To gain an understanding of the thermodynamic and molecular origin of these large rate enhancements, we performed a Diels-Alder reaction between cyclopentadiene and methyl acrylate at ionic liquid/n-hexane interfaces. This study describes, for the first time, a methodology for the calculation of the activation parameters of an interfacial reaction. It has been seen that the energy of activation for an interfacial reaction is much smaller than that of the corresponding homogeneous reaction, resulting into the large rate acceleration for the interfacial reaction. Furthermore, the study describes the effects of the alkyl chain length of ionic liquid cations, the extent of heterogeneity, and the polarity of ionic liquids on the rate constants and stereoselectivity of the reaction.

Coordination of terpyridine to Li+ in two different ionic liquids

On the basis of 7Li NMR experiments, the complex-formation reaction between Li+ and the tridentate N-donor ligand terpyridine was studied in the ionic liquids [emim][NTf2] and [emim][ClO 4] as solvents. For both ionic liquids, the NMR data implicate the formation of [Li(terpy)2]+. Density functional theory calculations show that partial coordination of terpyridine involving the coordination of a solvent anion can be excluded. In contrast to the studies in solution, X-ray diffraction measurements led to completely different results. In the case of [emim][NTf2], the polymeric lithium species [Li(terpy)(NTf2)]n was found to control the stacking of this complex, whereas crystals grown from [emim][ClO4] exhibit the discrete dimeric species [Li(terpy)(ClO4)]2. However, both structures indicate that each lithium ion is formally coordinated by one terpy molecule and one solvent anion in the solid state, suggesting that charge neutralization and π stacking mainly control the crystallization process.

Gutmann donor and acceptor numbers for ionic liquids

We present for the first time Gutmann donor and acceptor numbers for a series of 36 different ionic liquids that include 26 distinct anions. The donor numbers were obtained by 23Na NMR spectroscopy and show a strong dependence on the anionic component of the ionic liquid. The donor numbers measured vary from -12.3 kcala mol-1 for the ionic liquid containing the weakest coordinative anion [emim][FAP] (1-ethyl-3-methylimidazolium tris(pentafluoroethyl)trifluorophosphate), which is a weaker donor than 1,2-dichloroethane, to 76.7 kcala mol-1 found for the ionic liquid [emim][Br], which exhibits a coordinative strength in the range of tertiary amines. The acceptor numbers were measured by using 31P NMR spectroscopy and also vary as a function of the anionic and cationic component of the ionic liquid. The data are presented and correlated with other solvent parameters like the Kamlet-Taft set of parameters, and compared to the donor numbers reported by other groups. Give and you shall receive: The Gutmann donor and acceptor numbers (DNs and ANs) for a series of 36 different ionic liquids that include 26 distinct anions are presented. The DNs and ANs were obtained by 23Na and 31P NMR spectroscopy, respectively. Both values showed a strong dependence on the anionic and cationic components of the ionic liquid. The data are presented and correlated with other solvent parameters and compared to donor numbers reported by other groups. Copyright
