Abstract
In the combustion of carbon disulfide, the direct substitution reaction O + CS2 = OCS + S (I) was found to be the main source of atomic sulfur, which is responsible for the branching of reaction chains. As distinct from the reactions of intermediate products with each other, step (I), which is a first-order reaction with respect to the concentration of chain carriers, together with an act of multiplication of active species, is responsible for not only flame propagation but also critical self-ignition conditions.
