Conductivity and Viscosity of 1-Allyl-3-methyl-imidazolium Chloride + Water and + Ethanol from 293.15 K to 333.15 K

Abstract

The room-temperature ionic liquid 1-allyl-3-methyl-imidazolium chloride [amim][CI] was synthesized. The conductivities and viscosities of [amim][CI] + water and + ethanol binary mixtures were determined in the temperature range from 293.15 K to 333.15 K, and the mole fraction of the solvents in the mixtures was in the range of 0 to 0.80 for water and 0 to 0.55 for ethanol. The conductivities of the mixtures increased with increasing concentration of the solvents and temperature in the solvent concentration range studied. The viscosities of the mixtures decreased with increasing temperature.

Regenerating cellulose from ionic liquids for an accelerated enzymatic hydrolysis

“…It was reported having m.p. of ∼17 • C and viscosity of 685 mPa s at 30 • C (Zhang et al, 2005); but a different viscosity value (1127.7 mPa s at 30 • C) appeared in the Supporting Information of a recent paper (Remsing et al, 2008), while another group obtained much lower viscosities of 66 mPa s at 20 • C and 44.7 mPa s at 30 • C (Xu et al, 2005). However, a recent study suggested this IL crystallizes after purification (m.p.…”

Ionic Liquid as Reaction Media for the Production of Cellulose-Derived Polymers from Cellulosic Biomass

“…In the same work, it was also concluded that the presence of water and other molecular co-solvents reduces the viscosity of ILs. For example, viscosities of binary mixtures [112] While the addition of molecular solvents to an IL decreases the solution viscosity, the addition of cellulose increases drastically the viscosity of the mixture. Concentrated cellulose/IL solutions show non-Newtonian behavior.…”

Measurement and modeling of osmotic coefficients of aqueous solution of ionic liquids using vapor pressure osmometry method

“…These papers mainly report these quantities for whole composition range of ionic liquids in water, and only some other works have been performed for dilute region solution of ionic liquids [7][8][9][10][11][12][13][14][15][16]. It is well known that ionic liquids can be viewed as kind of organic electrolyte.…”
