Influence of Functional Sulfonic Acid Group on Pyrolysis Characteristics for Cation Exchange Resin

Gradual and stepwise pyrolyses of insoluble organic matter from the Murchison meteorite revealing chemical structure and isotopic distribution

“…Assuming that the IOM contained these bonds, they should be broken at low temperatures and generate SO 2 and OCS from the sulfo groups, OCS and CS 2 from the sulfide linkages, and H 2 S and alkyl thiols from the thiol groups. This inference supports the claim that the sulfo groups attached to resins decompose at about 300°C and generate SO 2 (Matsuda et al, 1987). The sulfur-bearing compounds discussed above exist in the linkage and substituent portion of the IOM.…”

Treatment of spent radioactive anionic exchange resins using Fenton-like oxidation process

“…Several volume reduction methods, e.g. incineration [16] and pyrolysis [17] can get high percentage of volume reduction. However, secondary waste will be produced in these processes.…”

Sulfonation and Characterization of Tert-Butyl Styrene/Styrene/Isoprene Copolymer and Polypropylene Blends for Blood Compatibility Applications

“…Besides, the sulfonated blended samples showed a higher thermal degradation temperature compared to those without sulfonation, except the pure PP (i.e., tSEPS% = 0). This can be attributed to the formation of the sulfonic bridge/sulfuric bridge, a linkage similar to the vulcanization, which led to the increase in thermal degradation temperature [28,29]. The tensile strength and the strain at break for different blending samples before and after the sulfonation are shown in Table 7 and Figure S3 in Supplementary Material.…”
