An acid-functionalized magnetic ionic liquid, 1-carboxymethyl-3-methylimidazolium tetrachloroferrate, was utilized for the synthesis of a series of novel highly functionalized (coumarinyl)pyrido[2,3-d]pyrimidine-2,4-diones I (R1 = H,Br, Cl, MeO; R2 = H, Cl, Br; R3 = Me, cyclopropyl) by the reactions of various 3-chloro-3-(2-oxo-2H-chromen-3-yl)acrylaldehydes II with functionalized 6-aminouracils III. The central point of the present procedure was the use of task-specific acidic ionic liquid which acts as catalyst as well as reaction medium thus avoiding the use of organic solvent and/or protic acid catalyst. The other major advantages of the protocol were (i) shorter reaction time (1 h), (ii) easy work up procedure, (iii) excellent yields of products (91-94%) and (iv) recyclability of the catalyst. The compounds I were identified using FT-IR, 1H-NMR and 13C-NMR and mass spectroscopic studies.

A novel electrochem. sensor for rutin determination based on molecularly imprinted poly (ionic liquid) (MIPIL)/ionic liquid-graphene (IL-GR) modified electrode was developed. MIPIL was synthesized via free radical polymerization using rutin as the template, 1-allyl-3-Et imidazolium bromide ([AEIm]Br) as the functional monomer and 1,4-butanediyl-3,3′-bis-L-vinylimidazolium dibromide ([V2C4(mim)2]Br2) as the crosslinker. The composite of IL-GR as an electrode sensitive element was prepared using carboxymethyl-3-methylimidazolium chloride ([HO2CMMIm]Cl) by one-step ultrasound method. Fourier transform IR spectroscopy and scanning electron microscope were used to characterize IL-GR and MIPIL. The increased surface area and conductivity of IL-GR/GCE improved the sensitivity of rutin sensor. Under the optimum condition, good linearity for rutin anal. by the MIPIL-based sensor was obtained from 0.03 to 1μM. A low limit of detection for rutin was 0.01μM (S/N = 3). The MIPIL-based sensor demonstrated superiority on DPV response compared to the imprinted sensors based on traditional crosslinkers. The proposed sensor presented good selectivity for rutin and successfully applied for rutin determination in tablets with RSD of 3.05% and the average recovery range was 98.3%.

Kong, Juanhua; Li, Lixia; Zeng, Qiang; Long, Jinxing; He, Hongyan; Wang, Yingying; Liu, Sijie; Li, Xuehui published the artcile< Production of 4-Ethylphenol from Lignin Depolymerization in a Novel Surfactant-Free Microemulsion Reactor>, HPLC of Formula: 700370-07-6, the main research area is ethylphenol lignin depolymerization surfactant microemulsion reactor.

In order to meet the requirements of sustainable development, the production of aromatic compounds from renewable biomass is of great concern. Herein, a surfactant-free microemulsion (SFME) system composed of n-octane, 2-propanol, and water was explored for the depolymerization of lignin though a hydrogen transfer reaction of 2-propanol with acidic ionic liquids (ILs) as catalysts. Exptl. results show that the phenol monomer yield from bagasse lignin in the SFME system is at least 4 times higher than that in its corresponding water-free binary system, together with a high selectivity for 4-ethylphenol of 67.8%. In particular, the results also reveal that the controllable polarity and large surface area of the SFME and the aggregation of lignin at the SFME surface are key factors in response to the enhanced yields of phenolic monomers through intensive characterizations. Mechanism studies imply that this system tailors mainly the esterified p-coumarate unit in lignin, and 4-ethylphenol is produced by a cascade reaction, involving hydrolysis, decarboxylation, and hydrogenation. Furthermore, this SFME system also exhibits excellent performance for the depolymerization of other herbaceous lignins, yielding 128.1 mg g-1 phenolic monomers with 59.1% 4-ethylphenol selectivity for corncob lignin. It is thus believed that the process intensification by microemulsion can significantly demonstrate unprecedented potential to accomplish highly efficient lignin conversion.

Yan, Kui; Bai, Zhengwu; Huang, Shaohua published the artcile< NMR signal separation of ionic liquids by poly(sodium-p-styrenesulfonate)-assisted chromatographic NMR spectroscopy>, Application of C6H9ClN2O2, the main research area is ionic liquid polysodium styrenesulfonate chromatog NMR spectroscopy.

Diffusion-ordered NMR spectroscopy (DOSY), dubbed chromatog. NMR spectroscopy, can be used to simultaneously distinguish and identify the structures of components in a mixture according to their different diffusion coefficients In order to improve the resolution of DOSY on the diffusion dimension, a lot of matrixes have been developed to expand the application of this technique in mixture anal. However, there is no matrix to detect the mixture of ionic liquids (ILs). Herein, we introduced a new matrix, poly(sodium-p-styrenesulfonate) (PSSNa), which can be used to fully sep. the signals of a mixture of different ILs. The mixture of three imidazolium ILs of 1-butyl-3-methylimidazolium bromide, 1-allyl-3-vinylimidazolium bromide and 1-carboxymethyl-3-methylimidazolium chloride could be fully distinguished by virtue of their different interactions with PSSNa. We also investigated the influences of PSSNa amount, IL concentration and solution pH value on the signal resolution of mixtures This work provides a scientific reference for the anal. of the other IL analytes.

Wang, Lizhi; Liu, Yang; Lu, Chanfang; Yang, Zhouping; Liu, Yaqing; Wang, Yanying; Rao, Hanbing; Zhang, Wei; Wang, Xianxiang published the artcile< Ultrasonic synthesis of nano-PrO1.8 as nanozyme for colorimetric determination of trans-resveratrol>, Recommanded Product: 1-carboxymethyl-3-methylimidazolium chloride, the main research area is trans resveratrol nanozyme colorimetric determination ultrasonic synthesis.

In this study, nano-PrO1.8 were synthesized successfully in ionic liquids (ILs) as template assisted ultrasonic irradiation method. Various precipitating agents and different types of ILs were investigated to determine their resp. effects on the morphol. of the end products. Using hydrazine hydrate as a precipitating agent and 1-carboxymethyl-3-methylimidazolium chloride as a template, spherical structure with an average diameter of 250 nm was obtained. It is worth noting that the prepared material exhibits high peroxidase-like activity and weak oxidase activity. Then, the catalytic oxidation capacity of the nano-PrO1.8 was evaluated by the peroxidase substrate 3,3′,5,5′-tetramethylbenzidine (TMB). The colorless of TMB can be converted into blue oxidized TMB (oxTMB) in the presence of nano-PrO1.8, but trans-resveratrol inhibited its peroxidase-like activity and weakened the blue color. Hence, we developed a sensitive, selective and simple colorimetric method for trans-resveratrol detection using nano-PrO1.8 as peroxidase-like enzyme. A linear relationship was found in the range of 0.30μM-16μM trans-resveratrol with the detection limit of 0.29μM. Satisfactory results were achieved when the method was submitted to the determination of trans-resveratrol in white wine samples.

Hernandez, Elisa; Santiago, Ruben; Belinchon, Alejandro; Maria Vaquerizo, Gema; Moya, Cristian; Navarro, Pablo; Palomar, Jose published the artcile< Universal and low energy-demanding platform to produce propylene carbonate from CO2 using hydrophilic ionic liquids>, Synthetic Route of 700370-07-6, the main research area is ionic liquid catalyst propylene carbonate carbon dioxide.

Ionic liquids (ILs) have been extensively proposed as efficient catalysts to promote CO2 cycloaddition reaction to epoxides for producing cyclic carbonates. Recently, liquid-liquid extraction with water as an enhancer approach to regenerate ILs and to purify the product was proposed, since it reduces energy consumption and enhances the neat catalytic activity of the IL due to hydroxyl groups of water. In this work, a comprehensive sample of homogeneous IL catalysts proposed in the literature is exptl. evaluated both in the catalytic step and in its separation by liquid-liquid extraction with water, to demonstrate the universality of the proposed reaction-separation proposal for hydrophilic ILs. Then the complete processes for CO2 conversion to propylene carbonate were modelled using Aspen Plus to compare the catalyst/product separation efficiency and the specific energy consumption using liquid-liquid extraction and distillation-based platforms. The energy consumption is significantly lower using liquid-liquid platform (1.1-1.3 kWh/kgPC) than distillation one (2.4-3.1 kWh/kgPC). It is concluded that hydrophilic ionic liquids, as those formed by [EtOHmim] cation and halide anions, are promising catalysts since they allow: (i) reducing the process energy consumption due to their high catalytic activity and (ii) full catalyst recovering, even at high catalyst loadings, by improving the water extractive properties for IL separation from PC.

A water-soluble and charge-tagged palladium complex (PdMAI) was found to function inside breast cancer live cells of the MCF-7 lineage as an efficient catalyst for cross-coupling reaction. PdMAI, bearing two ionophilic task-specific ionic liquids as ligands, efficiently catalyzed both in cellulo Suzuki and Buchwald-Hartwig amination reactions. For the first time, therefore, the Buchwald-Hartwig amination is described to occur inside the highly complex cellular environment. The 2,1,3-benzothiadiazole (BTD) core was used as the base for the syntheses, and two π-extended fluorescent derivatives (BTD-2APy) and (BTD-1AN), which were found to emit in the green and red channels, had impressive mitochondrial affinity. These chromophores allowed for selective mitochondrial imaging and tracking.
