Chloride anion-based ionic liquids (ILs) have unique importance among various ILs. Nevertheless, they are usually very viscous, and the study on their mixtures with molecular solvent is important for their practical application. In this work, the viscosities and conductivities of the binary mixtures of 1-butyl-3-methylimidazolium chloride and several protic/aprotic solvents were measured, and the underlying information about intermolecular interaction and microscopic structure was discussed. The result showed that the molecular solvents which have relatively high dielectric constant and hydrogen-bond acidity will be more efficient in promoting the dissociation of chloride anion-based ILs and improving the transport properties of corresponding applications.

Polyethylene glycol (PEG) esters are important, nontoxic and biodegradable non-ionic surfactants. A keyprocedure in producing PEG esters is their separation from unreacted or excess acids. We propose an adsorptionmethod using the weakly basic anion exchange resins for the separation of organic acids and PEG esters for the firsttime. With α-tocopheryl polyethylene glycol succinate (TPGS) and α-tocopheryl succinate (α-TS) as the examples ofPEG ester and organic acid, respectively, single-component equilibrium experiments revealed the great potential of thismethod. Studies on the adsorption equilibrium, thermodynamics and kinetics of α-TS onto a weakly basic anion exchangeresin were also carried out. This research is not only important for the production of TPGS, but also instructivefor the separation of other PEG-esters from the reaction mixtures.
