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.

Paragraph 0032-0033, (2017/02/24)
The invention relates to the synthesis of fine chemical intermediates, in particular to a synthesis method of di(2-halogenated ethyl) ether. According to the synthesis method, 1,4-thioxane-1,1-dioxo and a hydrogen halide water solution react with each other to obtain the target product, namely di(2-halogenated ethyl) ether. The synthesis method is simple and convenient in technical route, good in selectivity, high in yield, less in pollution and simple in post-processing, conforms to the tendency of the green chemical industry nowadays, and has great industrial value.
