Kinetic and Mechanistic Study of Oxidation of Diethylamine by N-Sodio-N- Bromobenzene Sulphonamide (Bromamine-B) in Acid Solution: Catalyzed by Ru(III)
نویسندگان
چکیده
Kinetics of oxidation of diethylamine (DEA) by Bromamine-B (BAB) has been investigated at in acid solution with Ru(III) as catalyst. The oxidation behavior obeys 303 K the rate law, rate 5 k [BAB] [DEA] [Ru(III)] [H1]2x where ‘x’ is less than unity indicating retardation of rate by [H]. Added halide ions, the reaction product benzenesulphonamide, variation of ionic strength and dielectric constant of the medium do not have any significant effect on the rate. The protonation constant of monobromamine-B evaluated for the reaction is 32.3 at Activation parameters have been evaluated from Arrhenius plot. A mechanism 303 K. consistent with experimental results has been proposed. q 1999 John Wiley & Sons, Inc. Int J Chem Kinet 31: 744–752, 1999

In this work, a polyimide (PI) containing triazole units was synthesized using 3,5-diamino-1,2,4-triazole and pyromellitic dianhydride in N-methyl-2-pyrrolidinone. This polymer was used as the support of manganese (III) tetrakis(4-methoxylphenyl)porphyrin acetate to attain a heterogeneous catalyst; namely Mn(T4-OMePP)OAc@PI. The synthesized PI and Mn(T4-OMePP)OAc@PI were characterized by di...
