Studies in the physical chemistry of detonation and related topics

The well-established physical theory of detonation specifies the properties of the infinite plane detonation wave in terms of the thermochemistry of the detonation reaction and the equation of state of the detonation products, (see, for example, Taylor, 1952). Thus physical chemistry has two roles in the discussion of the plane detonation wave, the provision of thermochemical information and the determination of the equation of state. This theory deals however with an ideal case, in which rate processes have no effect; in the real wave, complicated rate processes have to be taken into account. Here again physical chemistry has information to supply in the fields of chemical kinetics and rates of energy transfer. The present thesis deals with contributions to physical chemistry in the fields of thermochemistry, equation of state and intermolecular forces, chemical kinetics and energy transfer.LIST OF PAPERS: (1) The preparation and heats of combustion of some amine nitrates T.
