Elbs reaction experimental

Nevertheless the Elbs reaction is a valuable method for the preparation of dihydroxy benzenes. The experimental procedure is simple, and the reaction conditions are mild a variety of functional groups is tolerated. 

These experimental data are already sufficient to indicate that the photooxidation of gaseous ethanal takes place via a chain reaction. Accepting the processes of propagation suggested by Backstrom, von Elbe and Lewis wrote out a kinetic scheme which seems to be a special case of the mechanism we have already referred to in dealing with photooxidation of ethanal in the liquid phase, i.e., the case where termination processes (t4 and ts) are negligible in comparison with termination process (ta).
