Title: Gas phase oxidation of onion dehydration odors with ozone
Author: Purkaple, Jerry Dixon
Abstract: The kinetics of the reaction between ozone and three identified components associated with onion dehydration odor were studied in a flow reactor . Temperatures in the range of 95 -150°F were used in an attempt to estimate the temperature dependence of the reaction rate constant . However , this temperature range was not great enough to establish a meaningful relationship . A homogeneous gas phase model and a heterogeneous model were found to fit the experimental data reasonably well . Due to the mathematical similarities between the two models , no real distinction could be made between them . Initial rate data indicated that the initial reaction was first order with respect to the odor components and of fractional order with respect to ozone .
