Organic solvent nanofiltration: prospects and application

Solvent nanofiltration through high permeability glassy polymers: Effect of polymer and solute nature

“…Many advantages of this technology have already been underlined in the literature [1][2][3]. Meanwhile, one of the major drawbacks preventing implementation of this technology in industry is the limited number of membrane materials that offer high filtration performance (solvent permeability/retention) and at the same time show high chemical and mechanical stability.…”

Stabilization of gas transport properties of PTMSP with porous aromatic framework: Effect of annealing

“…Hydrophobic high free volume glassy polymers (or polymers of intrinsic microporosity) such as disubstituted polyacetylenes, polybenzodioxane PIM-1, and polynorbornenes are considered as promising membrane and sorbent materials for different gas and liquid-based applications [1][2][3][4][5][6][7][8][9][10][11]. The excess of free volume composed of interconnected free volume elements is naturally formed during the membrane casting due to rigid nature of polymer chains providing superior membrane permeability and solubility selectivity as compared with the performance of conventional glassy or rubbery polymers [1][2][3]9].…”

Ionic Liquids Recycling for Reuse

“…The combination of scCO 2 and ionic liquids seems to be a very promising approach to attain this goal. The simultaneous efficient nano-filtration recycling of ILs and homogeneous catalysts extends the possibilities of the practical application of these media in organic synthesis [Volkov et al 2008]. Destruction of ILs and removal of extracted organic contaminants by photolytic degradation is possibly another method of recycling ILs [Yang & Dionysiou, 2004;Khodadoust et al, 2006].…”
