The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature. 636-61-3, Name is (R)-2-Hydroxysuccinic acid, SMILES is O=C(O)[C@H](O)CC(O)=O, in an article , author is LEE, JJ, once mentioned of 636-61-3, HPLC of Formula: C4H6O5.
CATALYSIS OF DECARBOXYLATION OF 6-NITROBENZISOXAZOLE-3-CARBOXYLATE BY CATIONIC POLYMER COLLOIDS
Polystyrene latexes with quaternary ammonium ion-exchange sites catalyze the decarboxylation of 6-nitrobenzisoxazole-3-carboxylate in aqueous dispersions. A catalytic rate constant of 2.1 X 10(4) times the rate constant in water was achieved in particles containing 24 mol % of poly((styrylmethyl)tri-n-butylammonium chloride) repeat units. This is the largest rate enhancement reported at 25 degrees-C for decarboxylation of 6-nitrobenzisoxazole-3-carboxylate in any colloidal or polymeric medium. The decarboxylation kinetics fit both the enzyme model of micellar catalysis and an ion-exchange model. Added electrolyte decreases the rate of decarboxylation but increases the intrinsic catalytic rate constants in the more highly swollen latexes. The fraction of (styrylmethyl)trimethylammonium ion repeat units in the polymers has little effect on the rate of decarboxylation. The catalytic activity of the poly((styrylmethyl)trailkylammonium) ions in the latex increases in the order of in lipophilicity: Me < Et < Pr < Bu. The 200-350-nm diameter monodisperse colloidal particles with varied functional group content were prepared by emulsion copolymerization of styrene, (styrylmethyl)trimethylammonium chloride, divinylbenzene, and (chloromethyl)styrene followed by reactions with trialkylamines to form the anion-exchange sites.
