Abstract:

In order to gain an understanding of the explosive reactions of N-F compounds, a study has been made of the explosive reaction between tetrafluorohydrazine and hydrogen. The explosion is inhibited by substances capable of destroying hydrogen atoms. Tetramethylethylene is the most effective inhibitor of the substances tested. One part of this substance in 10,000 parts of reaction mixture completely suppresses the explosion. The reaction has the properties of a chain reaction initiated by the difluoroamino radical and having hydrogen atoms as one of the chain carriers. The stoichiometry and the products of the reaction depend in an unusual manner upon the presence of inert gas. Mechanisms are proposed for these reactions which are consistent with the experimental data. The intermediates, N2F3 and N2F2, which are believed to be formed in the reaction can react in different ways depending upon the relative abundance of the reactants and upon explosion temperature thus accounting for the peculiar features of this system.
