✦ Synopsis

The theoretical yield of HCN, calculated for a model which includes thirty flame reactions, is compared with experimental data for a flame of the same composition. In order to account for the observed low yields of HCN at low cyanogen flow rates it is necessary to postulate that the reaction OH + C: N2 -+ HOCN + CN, is sufficiently rapid to compete effectively with the reaction of hydrogen atoms with cyanogen in the cool part of the reaction zone. Other predictions of the model, such as the reduced H atom concentration and lowered burning velocity when C2N2 is introduced, and the low yield of NO from C2N2, are also consistent with experimental observations.
