Effect of the Reaction Products on the Rate of Oxidation of Crotonaldehyde

Study of the oxidation of crotonaldehyde revealed an appreciable inhibitory effect of the products on the process. Analysis of the kinetic data obtained over a wide range of reaction conditions (c₀ 1.5-3.3 M, pO₂ 1-16 atm, T 293-309 K) showed that the overall oxidation process (with account taken of the inhibitory effect of the products) is described by the equation: W_CA = k*_apc_CA (pO₂)^0.6 (1 + 0.17c_CA)^-1, where k*_ap is the apparent rate constant, and c_CA is the decrease of the aldehyde concentration by a moment .
