Explosion reaction of olefins : III. Explosion reaction of trans-butene-2-oxygen mixtures

Abstract

The explosion reaction of trans-butene-2(T2B) has been examined by means of gas chromatography under the following Conditions: temperatures, 480℃ and 430℃, composition, 40 and 50 vol% of T2B, respectively. Emphasis is placed on the detection of the intermediates of this reaction. It is found that the major intermediate of the explosion reaction is acetaldehyde and is identical with that of the slow combustion. It is confirmed that acetaldehyde is the intermediate of the reaction caused in the low temperature peninsula and plays a role in the isochor curves of type III. The production of acetaldehyde can be accounted for by considering that oxygen initially adds across the double bond in order to form cycloperoxide which decomposes subsequently.
