The kinetics of the interaction of atomic hydrogen with olefines VII. The competitive removal of hydrogen atoms by ethylene and propylene

Abstract

The relative efficiency of removal of hydrogen atoms by ethylene and propylene has been measured by making the two olefines compete in the same system for hydrogen atoms. It is found that propylene is about 1.6 times as reactive as ethylene, and this figure compares favourably with previous estimates by different methods. It is shown that the collision efficiency for the mutual reaction of ethyl radicals is similar to that for propyl radicals and to that for an ethyl and propyl radical.
