Sustainable hydrophobic terpene-based eutectic solvents for the extraction and separation of metals

03-Jul-2018 | Nicolas Schaeffer; Mónia Martins; Catarina Seiça Neves; Simão P. Pinho; Joao A. P. Coutinho, Chemical Communication, 2018

Sustainable hydrophobic eutectic solvents, composed of low-priced and biodegradable terpenes and fatty acids, were used for the extraction and separation of Cu(II) from other transition metals in mildly acidic solutions. Multiple parameters were evaluated for metal extraction and the hydrophobic ...

Continuous detection of HCl and NH3 gases with a high-performance fluorescent polymer sensor

03-Jul-2018 | Ning Xu; Rui-Lei Wang; Dong-Peng Li; Zi-Yan Zhou; Tian Zhang; Yu-Zhong Xie; Zhong-Min Su, New Journal of Chemistry, 2018

A novel fluorescent triazine-based covalent organic polymer (COP-1) sensor toward HCl and NH3 gases has been designed and synthesized. Both the COP-1 powders dispersed in solvents and the COP-1 film formed on surface of quartz sheets exhibit stable fluorescence and sensitive HCl/NH3 response. ...

First-principles calculations of oxidation potentials of electrolytes in lithium–sulfur batteries and their variations with changes in environment

03-Jul-2018 | Jaebeom Han; Perla B. Balbuena, Physical Chemistry Chemical Physics, 2018

Oxidation potentials of electrolyte molecules in Li–sulfur (Li/S) batteries and their variations in various solvent environments are investigated using first-principles calculations in order to understand oxidative decomposition reactions of electrolytes for cathode passivation. Electrolyte ...

Deep eutectic–water binary solvent associations investigated by vibrational spectroscopy and chemometrics

03-Jul-2018 | R. Ahmadi; B. Hemmateenejad; A. Safavi; Z. Shojaeifard; A. Shahsavar; A. Mohajeri; M. Heydari Dokoohaki; A. R. Zolghadr, Physical Chemistry Chemical Physics, 2018

Investigation of the behaviour of deep eutectic solvents (DESs) as novel green solvents in the presence of other solvents is of great interest. In this study the behaviour of a common natural DES, namely choline chloride–glycerol deep eutectic solvent (GDES), was studied in the presence of water. ...

Spatially encoded diffusion-ordered NMR spectroscopy of reaction mixtures in organic solvents

26-Jun-2018 | Ghanem Hamdoun; Ludmilla Guduff; Carine van Heijenoort; Christophe Bour; Vincent Gandon; Jean-Nicolas Dumez, Analyst, 2018

Diffusion-ordered NMR spectroscopy (DOSY) is a powerful method for the analysis of mixtures. Classic DOSY methods require several minutes of acquisition, and we show here that DOSY experiments can be recorded in less than one second for the challenging case of solution mixtures in low-viscosity ...

Trihalide ionic liquids as non-volatile oxidizing solvents for metals

26-Jun-2018 | Arne Van den Bossche; Elise De Witte; Wim Dehaen; Koen Binnemans, Green Chemistry, 2018

Various ionic liquids containing a trihalide anion [X3]- (X = Cl, Br or I) were synthesized by addition of molecular chlorine, bromine or iodine (X2) to a halide ionic liquid precursor, forming the trihalide anion via a Lewis acid-base reaction. All ionic liquids were characterized by 1H NMR, 13C ...

Pyrimidine-containing [small beta]-iminoenolate difluoroboron complexes acting as non-traditional [small pi]-gelators and mechanofluorochromic dyes

26-Jun-2018 | Wenhua Mi; Zhiyu Qu; Jingbo Sun; Fushuang Zhang; Lu Zhai; Jinyu Zhao; Kaiqi Ye, New Journal of Chemistry, 2018

New pyrimidine-containing β-iminoenolate CPPA and TCPPA and their difluoroboron complexes CPPAB and TCPPAB were synthesized. It was found that TCPPA and TCPPAB bearing tert-butyl could self-assemble into organogels in methylcyclohexane/1,4-dioxane and other solvents, but no organogel could be ...

Small-angle X-ray scattering study on nano-scale structures controlled by water content in a binary water/ionic liquid system

26-Jun-2018 | Kei Hashimoto; Kenta Fujii; Takumi Kusano; Kazu Hirosawa; Mitsuhiro Shibayama, Physical Chemistry Chemical Physics, 2018

We report the water-in-ionic-liquid microemulsions (ME) formed in a binary water/ionic liquid system, without organic solvents, using a surfactant ionic liquid (SAIL) based on 1-butyl-3-methylimidazolium (C4mIm+) as the cation and dioctyl sulfosuccinate (AOT−) as the anion. Small-angle X-ray ...
