Chemical Research Letters, May 2021. In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. 90-27-7, Name is 2-Phenylbutanoic acid, molecular formula is C10H12O2, Formula: https://www.ambeed.com/products/90-27-7.html, belongs to benzisoxazole compound, is a common compound. In a patnet, author is WANG, GJ, once mentioned the new application about 90-27-7.
Cross-linked, hydrophobically associating homo- and copolymers were synthesized by free-radical cyclo(co)polymerization of alkylmethyldiallylammonium bromide monomers with a small amount of N,N’-methylenebisacrylamide in aqueous solution using ammonium persulfate as the initiator. The cross-linked homo- and copolymers showed a increase of their reduced viscosity in water and intrinsic viscosity in 1.0 M sodium chloride solutions upon the controlled introduction of crosslinking N,N’-methylenebisacrylamide into their chemical structure. Depending on the hydrophobic group content of the cross-linked copolymers, a conformational transition was revealed by viscosity measurements which is accounted for by intramolecular micelle formation and intermolecular aggregation. The hydrophobic microdomains of the cross-linked polysoaps were characterized by hypsochromic shifts of the long-wavelength absorption band of methyl orange as a solvatochromic probe, noncovalently bound to the macromolecule. Catalysis of the unimolecular decarboxylation of 6-nitrobenzisoxazole-3-carboxylate by the cross-linked copolymers was investigated in aqueous solution at pH 11.3 and 30 degrees C. The cross-linked polysoaps exhibited higher catalytic activities for decarboxylation than the corresponding non-cross-linked copolymer analogues. A maximum in rate constant was found at about 0.2% (w/w) of cross-linking agent in the cross-linked copolymers.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. In my other articles, you can also check out more blogs about 90-27-7. Formula: https://www.ambeed.com/products/90-27-7.html.
