Abstract null null Developing new materials for the separation of gas mixtures is a key subject in setting up a circular economy. In this work, we report the synthesis and application of novel polymeric membranes, based on polymerized ionic liquids (PILs), to be used for CO2 separation from different gas pairs. Phosphonium-based PILs have been copolymerized within an original acrylate formulation that allowed the development of dense membranes able to overcome some of the main limitations relate...

Cannabis sativa L. is a multi-purpose crop, whose resilience, adaptability and soil-enriching properties make it a low-impact production. In the last years, the cultivation of the “industrial” hemp varieties (THC < 0.2%) has been promoted by many Countries, opening a whole new market of hemp-derived products, such as its essential oil (EO). Its distillation might represent an effective method to exploit a residue of the hemp fiber production (flowers), complying with the guidelines of the circul...

Four divalent ionic liquids based on imidazolium cations with alkyl or ether functionalized side-chains were synthesised and characterized: 3,3′-(tetraethyleneglycol-1,11-diyl)bis(1-methyl-1H-imidazolium)bromide, [tetraEG(mim)2][Br]2, 3,3′-(tetraethyleneglycol-1,11-diyl)bis(1-methyl-1H-imidazolium)acetate, [tetraEG(mim)2][OAc]2, 1-butyl-3-methylimidazolium malonate, [C4mim]2[Mal], and 3-butyl-1-methylimidazolium glutarate, [C4mim]2[Glut]. Their densities vary between 1.1 and 1.5 g cm−3 and their...

Abstract Six esters of both betaine and l -carnitine bromides, featuring alkyl groups ranging from C8 to C18 in length, have been synthesized. The thermal behaviour of these twelve bio-based salts has been analyzed and compared by thermal gravimetric analysis and differential scanning calorimetry. The l -carnitine alkyl ester bromides melted below 100 °C and can hence be considered ionic liquids (ILs) with full rights. Conversely, the betaine alkyl ester bromides, with the exception of the short...

Benzimidazole dicationic ionic liquids (BDILs) have not yet been widely explored in spite of their potential. Therefore, two structurally related families of BDILs, paired with either bromide or bistriflimide anions and bearing alkyl spacers ranging from C3 to C6, have been prepared. Their thermal properties have been studied by thermogravimetric analysis (TGA) and differential scanning calorimetry (DSC), while their electrical properties have been assessed by cyclic voltammetry (CV). TG analysi...

Abstract The evaporation/thermaldecompositionbehaviour of twoionicliquids with phosphoniumcation (PhosphoniumIonicLiquids, PhosphoniumILs,), namelytetraoctylphosphonium bis(trifluoromethylsulfonyl)imide ([P8888]NTf2) and tetraoctylphosphonium perfluorobutylphosphonate ([P8888]NFBS) wasstudied by thermogravimetryand by the effusion-basedtechniques Knudsen Effusion Mass Spectrometry (KEMS) and Knudsen Effusioni Mass Loss (KEML). KEMS spectra show that no appreciable release of decomposition produc...
