The separation of aromatic hydrocarbons (benzene, toluene, ethyl benzene and xylenes) from C4 to C10 aliphatic hydrocarbon mixtures is challenging since these hydrocarbons have boiling points in a close range and several combinations form azeotropes. In this work, we investigated the separation of toluene from heptane by extraction with ionic liquids. Several ionic liquids are suitable for extr...
The non-flammability and high oxidation stability of sulfolane (SL) make it an excellent electrolyte candidate for lithium-ion batteries (LIBs). However, its incompatibility with graphitic anode prevents the realization these advantages. To understand how this arises on molecular level so that can be suppressed, we combined theoretical calculation experimental characterization reveal primary Li...
The free radical 2,2-diphenyl-1-pycrylhydrazyl (DPPH) was tested as a polarising agent for fast dissolution dynamic nuclear polarisation (DNP) NMR spectroscopy. DPPH was found to be reasonably soluble in sulfolane and the optimum concentration for DNP is 20-40 mM depending upon whether short polarisation times or the maximum signal intensity is needed. W-band ESR measurements revealed that the ...
Abstract A study is performed of the possibility using gas–liquid chromatography (GLC) to determine composition solutions lithium salts in aprotic dipolar solvents and solvate ionic liquids. The objects are perchlorate trifluoromethanesulfonate sulfolane complexes with obtained two ways: direct interaction initial components a given molar ratio common solvent its subsequent removal via evaporat...
