Summary
-
1.
The oxidation of propane by oxygen in the presence of chlorine at various temperatures (327, 340, 358, and 372°) was studied by measuring the heating of the mixture during the reaction.
-
2.
When chlorine was introduced into the system C3H3+ O2, two heat-evolution maxima were clearly observed and these indicated that there are two macroscopic stages, separate in time, in the reaction mechanism.
-
3.
By calculation, it was shown that two heat-evolution maxima may be obtained when there occur two degenerate branched stages in which a product of the first stage produces degenerate branching of the chain in the second stage.
