Selection thermal stability

The study of ILs in GLC has yielded important information regarding solute-solvent interactions providing valuable insights into their complex solvation interactions and thermodynamic properties for mixed solvent systems. Moreover, ILs have proven to be an important new class of stationary phases for the separation of a wide variety of different analytes. IL stationary phases will soon be commercially available which will inevitably promote further improvements in separation selectivity, thermal stability, immobilization bonding chemistry/stationary phase stability, and will broaden the range of separated compounds. IL-based stationary phases also hold great promise in GC mass spectrometry where the dual-nature selectivity of the stationary phase eliminates the need for frequent changing of columns.

Bottom product of the ED column is fed to the stripper to separate pure aromatics from the solvent. After intensive heat exchange, the lean solvent is recycled to the ED column. NFM perfectly satisfies the necessary solvent properties needed for this process including high selectivity, thermal stability and a suitable boiling point.

A lot of works reported that multiblock cojwlymer showed higher water uptake, proton conductivity, proton/methanol selectivity, thermal stability, etc. than a similar random copolymer [61-63]. Liang et al. [64] have shown recently the morphology differences between random and multiblock copolymers (Scheme 4.11, Table 4.6) and the effects of the membrane morphology on the properties of the membranes.
