Abstrakt: The effect of the ratio of the reagents on a stabilized cool flame (CF) of rich propane-oxygen mixtures is investigated. It is found that with an increase in the initial concentration of propane in the mixture, its consumption, as well as the concentration of propylene, has a maximum at a ratio of C3H8 : O2 = 1 : 1. In this case, the selectivity of propylene formation reaches a maximum at a ratio of C3H8 : O2 = 4 : 1. It is shown that an increase in the initial propane concentration in the mixture increases the yield of methane, but reduces the yield of propylene, ethylene, hydrogen, CO, CO2, methanol, formaldehyde and acetaldehyde. At a ratio of C3H8 : O2 = 6 : 1, ethane was also found in the reaction products. The possibility of ethanol formation in the reactions of ethoxyl and hydroxyethyl radicals with acetaldehyde is analyzed using the CBS-QB3 quantum-chemical method. [ABSTRACT FROM AUTHOR]
