In this study, maleic anhydride-acylated chitosan (MAAC) was synthesized by modifying chitosan with maleic anhydride, and used to support palladium catalysts. N-maleyl chitosan-supported palladium (Pd/MAAC) was used as a heterogeneous catalyst for the Heck coupling reaction and reduction of 4-nitrophenol (4-NP). The chem. structure of Pd/MAAC was characterized using FT-IR XPS, XRD, XPS, TEM, SEM/EDS, N2-physisorption (adsorption-desorption), and ICP-MS. The as-synthesized catalyst exhibited high catalytic performance and could be reused up to nine runs to catalyze the cyclic reaction between iodobenzene and Bu acrylate with low leaching of palladium. Pd/MAAC was also used for the reduction of 4-NP to 4-aminophenol(4-AP) in 90 s at room temperature, and could be reused six times. The findings establish that Pd/MAAC catalyst is an efficient, economical, practical, and environment-friendly catalyst for the Heck reaction and reduction of 4-NP. This study involved multiple reactions and reactants, such as Sodium tetrachloropalladate(II) (cas: 13820-53-6Related Products of 13820-53-6).
Sodium tetrachloropalladate(II) (cas: 13820-53-6) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Related Products of 13820-53-6
