Supported ionic liquid membranes for the separation of methanol/dimethyl carbonate mixtures by pervaporation

Continuous Flow Upgrading of Selected C2–C6Platform Chemicals Derived from Biomass

“…The development of efficient, reliable and scalable tools for both upstream (biomass to platforms) and downstream (platforms to added value molecules) in-line purifications amenable for the specifications of bio-based chemicals can be foreseen as an important research field for the next decade (Perspective 4 , In-line purification, Figure ). Other technologies such as in-line distillation , and pervaporation − present great potential of development. However, they have not been applied yet to the separation in continuous flow of bio-based components.…”

Ionic liquids membranes for liquid separation: status and challenges

“…128 Li et al synthesized two SILMs based on [OMIM][Tf 2 N] and N-octyl-N-methylpyrrolidinium bis(triuoromethanesulfonyl) imide the separation of dimethyl carbonate (DMC) and methanol. 129 In addition, Xi and coworkers also developed an ILPM by copolymerizing an IL with waterborne polyurethane for benzene and cyclohexane separation. 130 In our previous review, we discussed how the ILM technique has been successfully employed for the selective separation of organic acids, including but not limited to lactic acid (LA), salicylic acid (SA), and 3-phenoxyproionic acid.…”

“…In addition, the ILMs were also used in the separation of specific substances from other solution systems, such as pervaporation, biomass separation, electrolyte, and cyanidation leaching solutions. 123,129 Pervaporation is assigned to separate binary or multicomponent liquid mixtures, such as azeotropes, isomers, and components with close boiling point. 129 A novel polyvinyl alcoholbased hydrophilic ionic liquid membrane was developed for the recovery of biobutanol through pervaporation.…”
