“…Decomposition of the ILs appears to transpire in a single step based on the thermograms. According to Mathew et al, decomposition of P[VBTMA][Cl] starts at 230 °C and ends at 370 °C [ 31 ]. [BMIM][Gly], on the other hand, begins to decompose around 210.35 °C [ 32 ].…”

The ability to efficiently separate CO2 from other light gases using membrane technology has received a great deal of attention due to its importance in applications such as improving the efficiency of natural gas and reducing greenhouse gas emissions. A wide range of materials has been employed for the fabrication of membranes. This paper highlights the work carried out to develop novel advanced membranes with improved separation performance. We integrated a polymerizable and amino acid ionic liquid (AAIL) with zeolite to fabricate mixed matrix membranes (MMMs). The MMMs were prepared with (vinylbenzyl)trimethylammonium chloride [VBTMA][Cl] and (vinylbenzyl)trimethylammonium glycine [VBTMA][Gly] as the polymeric support with 5 wt% zeolite particles, and varying concentrations of 1-butyl-3-methylimidazolium glycine, [BMIM][Gly] (5–20 wt%) blended together. The membranes were fabricated through photopolymerization. The extent of polymerization was confirmed using FTIR. FESEM confirmed the membranes formed are dense in structure. The thermal properties of the membranes were measured using TGA and DSC. CO2 and CH4 permeation was studied at room temperature and with a feed side pressure of 2 bar. [VBTMA][Gly]-based membranes recorded higher CO2 permeability and CO2/CH4 selectivity compared to [VBTMA][Cl]-based membranes due to the facilitated transport of CO2. The best performing membrane Gly-Gly-20 recorded permeance of 4.17 GPU and ideal selectivity of 5.49.

“…The weight loss corresponds to the loss of trimethylamine groups. 58,59 The terpolymers exhibited the second weight-loss stage in the range of homopolymers. For the terpolymers that were obtained by the microemulsion technique, the weight loss was between 14 and 18 wt%, and the temperature values for the rst derivative peak were found between 270 and 277 C. This decomposition was also observed in the DSC curves between 270 and 277 C (Fig.…”

In present study, several isatin-derived quaternary ammonium surfactants with different carbon chain lengths were designed and synthesized. They were synthesized by alkylation of indoline-2,3-dione with various dibromo-alkanes, then quaternization with trimethylamine. Nuclear magnetic resonance (1H NMR, 13C NMR) and mass spectroscopy were employed to examine their chemical structures. Further, the critical micelle concentrations (CMC) value of surfactants synthesized was determined in an aqueous solution using electrical conductivity. The synthesized surfactants had CMC ranging from 0.01 to 0.012 mol/L. The antibacterial activity of the titer compounds (3a-3c) was evaluated against Gram-negative bacteria (Pseudomonas aeruginosa and Escherichia coli), as well as Gram-positive bacteria (Staphylococcus aureus). The surfactant with a long hydrocarbon chain (12 carbons) showed activity against all bacteria tested (minimum inhibitory concentration = 1.25-2.5 mg/mL), whereas those with a short hydrocarbon chain proved to be inactive.
