Synthesis, characterization and reverse osmosis performance of poly(amide-sulfonamide)s

Scalable, Chemoselective Nickel Electrocatalytic Sulfinylation of Aryl Halides with SO2

“…Sulfur‐containing functional groups in the S VI ‐oxidation state appended to arenes are widespread in products of societal importance such as medicines, agrochemicals, and other functional materials [1–8] . One of the most convenient precursors to these essential derivatives is aryl sulfinates, existing in the S IV ‐oxidation state.…”

Water-alcohol separation by pervaporation through poly(amide-sulfonamide)s (PASAs) membranes

“…The reasonable water flux rate observed for PASA membranes in the RO process reported elsewhere supported this claim. 11 Thus, at the outset of this work, we believed that PASAs would be a viable material to prepare hydrophilic dehydration membranes ap- Because the intrinsic viscosity of the synthesized polymeric materials in our hand was quite varied, the concentration of each polymer in the casting solutions was needed to be adjusted in a range of 10.0-17.0%. The higher the intrinsic viscosity of the polymer, the lower its concentration required in the casting solution.…”

“…Furthermore, the innovation may result in widening the scope of potential of this membrane material used in the applications of the technology, the needs for reverse osmosis process has been explored in our searching new polymeric materials for membrane laboratory. 11 On the other hand, over the past 10 applications have been a continuous research years, membrane pervaporation has emerged for challenge. [2][3][4][5][6] For instance, with regard to the dethe chemical industry as an effective process tool velopment of new materials, the U.S. Department for separation and recovery of liquid mixture, inof Energy identified ''pervaporation membrane for cluding dehydration of alcohols.…”

Scalable, Chemoselective Ni-Electrocatalytic Sulfinylation of Aryl Halides with SO2

“…Sulfur-containing functional groups in the S(VI)-oxidation state appended to arenes are widespread in products of societal importance such as medicines, agrochemicals, and other functional materials. [1][2][3][4][5][6][7][8] One of the most convenient precursors to these essential derivatives is aryl sulfinates, existing in the S(IV)-oxidation state. These can be considered as versatile gateway intermediates to numerous desirable functionalities in either the S(IV) or S(VI) oxidation state such as sulfoxides, sulfinate esters, sulfinamides, sulfinyl chlorides, sulfonamides, sulfonyl halides, sulfones, and sulfonate esters (Figure 1A).…”
