Additives in slowly reacting mixtures of hydrogen and oxygen

2 ADDITIVES IN SLOWLY REACTING MIXTURES OF HYDROGEN AND OXYGEN 

The investigations outlined in Sect. 4, and particularly in Sect. 4.2, have shown that the slow reaction in H2 + N2 + O2 mixtures in aged boric acid coated vessels at around 773 K provides an extremely reproducible and controllable source of the radicals H, O, OH and HO2. Following the establishment of a detailed mechanism and the evaluation of the rate coefficients of the individual steps, the system has recently been exploited, particularly by Baldwin and co-workers, in order to examine the reactions of the radicals with small additions of foreign materials. With say 1 % of a hydrocarbon additive, the technique is to follow the rate of the
