UNLABELLED BACKGROUND The analysis of cellulose molecular weight distributions by gel permeation chromatography (GPC) is a powerful tool to obtain detailed information on enzymatic cellulose hydrolysis, supporting the development of economically viable biorefinery processes. Unfortunately, due to work and time consuming sample preparation, the measurement of cellulose molecular weight distri...

The structural properties of ionic liquid/rubrene single-crystal interfaces were investigated using frequency modulation atomic force microscopy. The spontaneous dissolution of rubrene molecules into the ionic liquid was triggered by surface defects such as rubrene oxide defects, and the dissolution rate strongly depended on the initial conditions of the rubrene surface. Dissolution of the seco...

Ethylammonium Propionate with high polarity and ionic conductivity was synthesized andcharacterized with 1HNMR and IR. This ionic liquid which is prepared from readily available startingmaterial in high yield shows reasonably high at viscosity and heat stability up to 150 °C. This IonicLiquid is able to dissolve most of organic solvents due to the hydrogen interaction between IonicLiquid and th...

Liquid-liquid extraction is an alternative method that can be used for desulfurization and denitrification of gasoline and diesel fuels. Recent approaches employ different ionic liquids as selective solvents, due to their general immiscibility with gasoline and diesel, negligible vapor pressure, and high selectivity to sulfur- and nitrogen-containing compounds. For that reason, five imidazolium...

This work explores the possibility of increasing the ionicity of ionic liquids via the solubilization of inorganic salts in their midst. The resulting purely ionic media-distinct ionic liquid plus inorganic salt mixtures-are liquid in an extensive concentration range and can be aptly denominated High Ionicity Ionic Liquids (HIILs).

The solvation and rotational relaxation dynamics of coumarin 153 have been investigated in a dicationic ionic liquid (IL), 1,6-bis-(3-methylimidazolium-1-yl)hexane bis-(trifluoromethylsulfonyl)amide ([C6(MIm)2][NTf2]2), for the first time to provide a comprehensive and a quantitative understanding of the nature of the ionic fluid and its influence on the average solvation and rotational relaxat...

N,N-Dimethylformamide (DMF) is a ‘universal’ solvent and has wide variety of applications in organic synthesis, purification, crystallization, and as cross-linking agent. The aim of this study was to evaluate the physicochemical and spectroscopic properties of DMF after the biofield energy treatment using various analytical techniques. DMF sample was divided into two parts, one part (control) r...

A carbon nanocomposite electrode has been designed by incorporation of montmorillonite nanoclayinto the carbon ionic liquid electrode for the electrochemical determination of amitriptiline . The surface ofthe proposed electrode was characterized by scanning electron microscopy. The presence of ionic liquid asa binder is believed to be responsible for the electrocatalytic activity of the propose...
