Description
Summary:3,3′-(Oxidi-2,1-ethanediyl)­bis­[1-methyl-imidazolium] dihexafluorophosphate ([C4O­(mim)2]­[PF6]2) was synthesized and confirmed with 1H NMR and FT-IR. The thermal stability of [C4O­(mim)2]­[PF6]2 was studied with differential scanning calorimetry and thermogravimetric analyses. Using the dynamic method, the solubility of [C4O­(mim)2]­[PF6]2 in five different pure solvents (water, methanol, ethanol, acetone, and acetonitrile) and binary mixtures (water + DMF) was measured at the temperature range from (283.00 to 323.00 K) at atmospheric pressure. The solubility of [C4O­(mim)2]­[PF6]2 in those selected solvents increased with increasing temperature and DMF contents, but the rate of solubility is different. The experimental data were correlated with the modified Apelblat equation. Also, the solubility of [C4O­(mim)2]­[PF6]2 and [C6O2(mim)2]­[PF6]2 was been compared in the same solvent.
