On April 30, 2021, Yuan, Chengyun; Wang, Yinghan published an article.Safety of 4,4′-Sulfonylbis(chlorobenzene) The title of the article was Synthesis and characterization of a novel sulfonated poly (aryl ether ketone sulfone) semi-crosslinked membrane with high proton selectivity through click reaction for direct methanol fuel cells. And the article contained the following:
A novel sulfonated polyvinyl alc. containing alkynyl groups (SPVA-CC) and a new sulfonated poly (aryl ether ketone sulfone) (SPAEKS) are synthesized. Semi-crosslinked membrane (semi-crosslink-SPAEKS-x) was prepared by click reaction of mercapto-alkynes between 1, 5-pentanedithiol and SPVA-CC. The chem. structures of SPAEKS, SPVA-CC and semi-crosslink-SPAEKS-x are confirmed by 1H-NMR and FTIR spectra. The semi-crosslink-SPAEKS-x membranes show good mech. properties, excellent dimensional stability and oxidative stability. The proton conductivity of SPAEKS and semi-crosslink-SPAEKS-x membranes is in the range of 25.6-52.5 mS/cm. The methanol permeability of semi-crosslink-SPAEKS-x membranes is in the range of 1.4-1.7 x 10-7 cm-2 s-1, which is much lower than that of Nafion 117 membrane (18.3 x 10-7 cm-2 s-1). Especially, the proton selectivity of semi-crosslink-SPAEKS-15 membrane (24.3 x 104 S s cm-3) is above seven times higher than that of Nafion 117 membrane (3.4 x 104 S s cm-3). The experimental process involved the reaction of 4,4′-Sulfonylbis(chlorobenzene)(cas: 80-07-9).Safety of 4,4′-Sulfonylbis(chlorobenzene)
