The oxidation of gaseous hydrocarbons has long attracted considerable interest on account pf its theoretical and practical importance. Early work was concerned entirely with the identification of the products of oxidation, and the postulation of plausible intermediate steps in their formation. As a result of such work Bone and his collaborators suggested the so-called "hydroxylation theory", which involved the orderly formation of hydroxyl compounds during oxidation, and their subsequent decomposition of further oxidation. This theory gives an excellent explanation of the intermediate and final products formed in the oxidation of most simple hydrocarbons. As far as the mechanism of the actual oxidation process is concerned, little progress was made until the development of the idea of thermal chain reactions. It is now generally conceded that the oxidation of most gaseous organic compounds proceeds by a chain mechanism. The main problem at the present time is to obtain some definite information regarding the carriers of the chains. One of the most useful attempts in this direction is the peroxide theory of Egerton, in which it is assumed that the initial step in the oxidation of organic compounds is the formation of an energy-rich complex with oxygen, which is called a "peroxide". Whether such a complex bears any real relation to actual stable alkyl peroxides is quite unknown.

A two-step generalized model of chemical kinetics of detonation combustion of propylene is presented. The model is consistent with the second law of thermodynamics and Le Chatelier’s principle. Constants of the models have a clear physical meaning. Owing to the simplicity (it includes only one ordinary differential equation) and high accuracy, the model can be used in multi-dimensional numerical calculations of detonation wave parameters and multi-front cellular structure.
