Constructing Porous Liquids with Poly(Ethylene Glycol) 4-Nonylphenyl 3-Sulfopropyl Ether Potassium Salt for CO2 Gas Adsorption

Su, Fangfang, et al. Separation and Purification Technology, 2021, 277, 119410.

This work reports a new type of Type Ⅰ porous liquids (PLs) based on hollow carbon spheres, which have hollow carbon spheres (HCS) as the porous body, polymer ionic liquids (PILs) and polyethylene glycol 4-nonylphenyl 3-sulfopropyl ether potassium salt (PEGS) as the canopy. The obtained HCS-PILs-PEGS has excellent fluidity and solution processability, and exhibits good CO2 adsorption performance. In addition, the CO2 adsorption performance of HCS-P[VHIm]Br-PEGS PLs are better than that of HCS-P[VBBI]Cl-PEGS.
Synthesis of HCS-PILs-PEGS
· Before the synthesis of HCS-PILs-PEGS, HCS nanoparticles were first prepared by hard template method. PILs (P[VBBI]Cl and P[VHIm]Br) were prepared by traditional free radical polymerization.
· HCS (0.5 g) was dispersed in DI H2O using ultrasound, while different types of PILs (1.0 g) were dissolved in DI H2O. The PILs solution was then added to the HCS-dispersed solution and stirred at 35 ◦C for 24 hours to create HCS@PILs.
· A concentrated PEGS water solution was added to the mixture and reacted at 70 ◦C for 24 hours to perform anion exchange. Once the reaction was complete, the sample was dried in an oven at 75 ◦C.
· Acetone was added to the dried sample, left to stand for 30 minutes, then the supernatant was removed before drying in the oven. The resulting PLs based on HCS were named HCS-PILs-PEGS. PLs based on different types of PILs were prepared using the same method.

Poly(Ethylene Glycol) 4-Nonylphenyl 3-Sulfopropyl Ether Potassium Salt Stabilized Palladium Nanoparticles for Selective Hydrogenation

La Sorella, Giorgio, et al. The Journal of Organic Chemistry, 2018, 83(14), 7438-7446.

In this work, anionic sulfonated surfactants (including polyethylene glycol 4-nonylphenyl-3-sulfopropyl ether potassium salt 1d) were used to stabilize Pd nanoparticles in aqueous media, and Pd particles with sizes ranging from 4.4 to 6.1 nm were successfully prepared. These Pd nanoparticles can be further used for selective hydrogenation reactions of aromatic alcohols, aldehydes, and ketones.
Synthesis and catalysis property of Pd@1d
· In a 10 ml round-bottomed flask with a magnetic stirrer, 1.6 mg of Pd(OAc)2 (2.4 mM) was added along with the appropriate surfactant (1a~1d) and 3 mL of double-distilled water under nitrogen.
· After stirring for 1 hour until complete dissolution of the metal complex, an orange homogeneous solution was obtained. The solution was then subjected to hydrogen flow for varying durations based on the surfactant used, leading to a color change from orange to grey indicating the formation of dispersed Pd-NPs.
· Among them, the hydrogenation reactions of benzaldehyde and other aromatic derivatives catalyzed by Pd@1d demonstrated high chemoselectivity towards benzyl alcohols. In contrast, Pd/C was less controllable, resulting in the production of deoxygenation reaction products.
