An experimental investigation in a conventional static apparatus of the oxidation of equimolecular mixtures 1,4‐dioxane‐O 2 has shown that 1,4‐dioxane reacts with oxygen more readily than most hydrocarbons. Cool flames and ignitions were observed above 200°C in a pressure range up to 300 torr. The products of the slow reaction and cool flame were analyzed by gas chromatography and GC‐MS; the slow reaction gives only CO, CO 2 , H 2 CO, H 2 , C 2 H 4 , and H 2 O. A radical chain mechanism is suggested and discussed by using an evaluation of the rate constants of the possible elementary steps by the methods of thermochemical kinetics.
