System A

The reaction of nitrogen atoms, produced by an electric discharge, with acetaldehyde has been studied in a flow system, a mass spectrometer being used to follow the course of the reaction. Sampling was carried out through a small hole in a gold diaphragm. The main stable products were HCN, H 2 and CO; a small amount of glyoxal was also formed. In addition appreciable amounts of a substance yielding ions of m/e = 43 were obtained. Arguments are presented for identifying this with the radical CH 2 CHO. Small amounts of a product giving ions of m/e = 86 were also produced. The nature of this material is discussed. No evidence was obtained for any hydrogen abstraction by nitrogen atoms. Experiments were also carried out with CH 3 CDO to clarify certain aspects of the proposed reaction mechanism . A few experimental results obtained with propionaldehyde can be understood in similar terms. The rate constant of the reaction N + CH 3 CHO → HCN + H 2 + HCO was deduced to be 1.20 ± 0.15 x 10 10 mole -1 cm 3 s -1 at 296°K.

Cyano Radical

The reactions of active nitrogen with acetylene, ethylene, and propylene have been studied in a flow system using a mass spectrometer to analyze the products continuously. Certain features of the mass spectra of the products can be explained on the basis of cyano radical replacement reactions.
