DOI: 10.1016/j.jiec.2019.05.031

Abstract: Abstract Chitosan-based polyelectrolyte complex membranes (PECMs) were developed by incorporating polystyrene sulfonic acid-co-maleic acid (PSSAMA) in the chitosan membrane matrix as a pervaporation membrane by employing a solution technique. Fourier transform infrared (FTIR) spectroscopy, wide-angle… read more here.

DOI: 10.1016/j.molliq.2021.117571

Abstract: Abstract In this work, two ionic liquids (ILs) 1-decyl-3-methylimidazolium bis(trifluoromethanesulfonyl)imide ([DMIM][NTf2]) and tributylmethylammonium bis(trifluoromethanesulfonyl)imide ([N4441][NTf2]) were synthesized and used to separate the methanol (MeOH) and methyl ethyl ketone (MEK) azeotropic system. The VLE data of… read more here.

DOI: 10.1021/acs.chemrev.3c00276

Abstract: This review discusses the research being performed on ionic liquids for the separation of fluorocarbon refrigerant mixtures. Fluorocarbon refrigerants, invented in 1928 by Thomas Midgley Jr., are a unique class of working fluids that are… read more here.
