Separation of Alcohols from n-Tetradecane Using 1-Ethyl-3-methylimidazolium Hydrogensulfate
نویسندگان
چکیده
Extraction of alcohols from n-tetradecane using various extraction solvents has been investigated at a range temperatures 295 to 393 K under ambient pressure. On the basis experimental liquid–liquid equilibrium data, distribution ratio and selectivity were calculated for 1-octanol, 1-decanol, 1-dodecanol (C8–C12) in 1-ethyl-3-methylimidazolium hydrogensulfate [C2mim][HSO4] sulfolane. Results showed that moderate selectivities obtained sulfolane with very low coefficients. In contrast, similar values higher A study number different 1-alcohols (C4–C12) decrease hydrogen bonding compared increased van der Waals interactions between higher-chain decreased [C2mim][HSO4]. Increasing temperature ionic liquid medium resulted chemical 1-butanol 1-hexanol due formation corresponding alkylsulfate liquid. 1-decanol partial dissolution into phase.

BACKGROUND Ionic liquids (ILs) are considered as suitable candidates for lignocellulosic biomass pretreatment prior enzymatic saccharification and, obviously, for second-generation bioethanol production. However, several reports showed toxic or inhibitory effects of residual ILs on microorganisms, plants, and animal cells which could affect a subsequent enzymatic saccharification and fermentati...

Recently, the use of ionic liquids (ILs) for carbon capture and separation processes has gained great interest by many researchers due to the high solubility of CO₂ in ILs. In the present work, solubility measurements of CO₂ in the novel IL 1-n-butyl-3-methylimidazolium nonafluorobutylsulfonate [C₄mim][CF₃CF₂CF₂CF₂SO₃] were performed with a high-pressure view-cell technique in the temperature r...

The electrosprays of 1-ethyl-3-methylimidazolium bis trifluoromethylsulfonyl imide are composed of a complex mixture of ions and charged droplets, which can be analyzed to determine the structure of the beam and infer significant features of the electrohydrodynamic atomization. In particular, we use a combination of retarding potential and time of flight techniques to study these beams and are ...
متن کاملSimulations of the water exchange dynamics of lanthanide ions in 1-ethyl-3-methylimidazolium ethyl sulfate ([EMIm][EtSO4]) and water.
The dynamics of ligand exchange on lanthanide ions is important for catalysis and organic reactions. Recent 17O-NMR experiments have shown that water-exchange rates of lanthanide ions in water/1-ethyl-3-methylimidazolium ethyl sulfate (water/[EMIm][EtSO4]) increase as a function of increasing charge density. The trend of water-exchange rates in this solvent is opposite to that observed in water...
