A comparison of the thermal and photochemical oxidation of 2‐propanol by two peroxoanionsAbstract The chain length (i.e., relative quantum yield) for the oxidation of 2‐propanol by peroxodisulfate ion at 25°C has been studied. A number of initial experiments were carried out in order to clarify the influence of dissolved oxygen, light intensity, cupric ion, and acetone absorption. After these problems were understood, conditions satisfactory for evaluat... ... hiện toàn bộ

Rate constants for the gas‐phase reactions of O3 with a series of monoterpenes and related compounds at 296 ± 2 KAbstract Rate constants for the gas‐phase reactions of O3 with a series of monoterpenes and related compounds have been determined at 296 ± 2 K and 740 torr total pressure of air or O2 using a combination of absolute and relative rate techniques. Good agreement between the absolute and relative rate data was observed, and th... ... hiện toàn bộ

Kinetics of the esterification of acetic acid with 2‐propanol: Impact of different acidic cation exchange resins on reaction mechanismAbstract The kinetics of the esterification of acetic acid with the secondary alcohol, 2‐propanol, catalyzed by the cation exchange resins, Dowex 50Wx8‐400, Amberlite IR‐120, and Amberlyst 15 has been studied at temperatures of 303, 323, and 343 K; acid to alcohol molar ratios of 0.5, 1, and 2; and catalyst loadings of 20, 40, and 60 g/L. The equilibrium constant wa... ... hiện toàn bộ

Kinetics study of propyl acetate synthesis reaction catalyzed by Amberlyst 15Abstract The reaction kinetics of esterification of acetic acid with n ‐propanol was investigated. The reaction was catalyzed by the commercial cation‐exchange resin Amberlyst 15, and the kinetic data were obtained in a batch reactor within the temperature range 338–368 K. The chemical equilibrium constant, K ... hiện toàn bộ

Kinetics and mechanism of oxidation of diethyl ketone by N‐bromosuccinimideAbstract Oxidative kinetics of diethyl ketone in perchloric acid media in the presence of mercuric acetate have been studied by using N ‐bromosuccinimide (NBS) as oxidant in the temperature range of 25°‐50°C. It has been found that the order with respect to NBS is zero while with respect to diethyl ketone and [H+ ], it i... ... hiện toàn bộ

A Chemical Kinetic Mechanism for 2‐Bromo‐3,3,3‐trifluoropropene (2‐BTP) Flame InhibitionABSTRACT In this work, we report a detailed chemical kinetic mechanism to describe the flame inhibition chemistry of the fire‐suppressant 2‐bromo‐3,3,3‐trifluoropropene (2‐BTP), under consideration as a replacement for CF3 Br. Under some conditions, the effectiveness of 2‐BTP is similar to that of CF3 Br; however, like other p... ... hiện toàn bộ

Nickel peroxide: A more probable intermediate in the Ni(II)‐catalyzed decomposition of peroxomonosulfateAbstract The Ni(II) ion catalyzed thermal decomposition of peroxomonosulfate (PMS) was studied in the pH range 3.42–5.89. The rate is first order in [PMS] and Ni(II) ion concentrations. At pH greater than or equal to 5.23, the reaction becomes zero order in [PMS] and this changeover in the order of the reaction occurs at a higher concentration of nickel ions. The fi... ... hiện toàn bộ

A pyrolysis mechanism for ammoniaAbstract The mechanism of NH3 pyrolysis was investigated over a wide range of conditions behind reflected shock waves. Quantitative time‐history measurements of the species NH and NH2 were made using narrow‐linewidth laser absorption. These records were used to establish an improved model mechanism for ammonia pyrolysis. The... ... hiện toàn bộ
