The pyrolysis of tertiary dibutyl peroxide

This reaction, carried out in the gas phase between about 120 and 300 °C, gives mainly acetone and ethane according to the following stoichiometric equation  

The experimental study has permitted the following kinetic law, of order 1, to be established  

The following mechanism has been proposed to take these observations into account  

First of all, it is obvious that this is really an open sequence reaction mechanism, as the two free radicals involved in this mechanism are not regenerated in the step following the one in which they first appear. 

The mechanism really is compatible with the stoichiometric equation. In fact, if the sum of the equations (31) + 2x(32) + (33) is carried out, equation (29) is found again.
