Experiments investigating the detonability of hydrazine - nitrous oxide mixtures are reported. No deton -s could be produced in mixtures containing less than 7 vol- of N2O. Pure hydra zine shows a detonation velocity of about 2450 msec. Spectroscopic investigations of the wake behind N2H4 detonations, however, revealed great amounts of NH3 which had not yet disappeared 300 mu sec behind the detonation front. Some evidence based on the pressure dependence in the NH3 production suggests that these detonations are inherently unstable. Shock-tube studies of the pyrolysis of nitrous oxide and hydrazine continued. Absorption coefficients of N2O up to 1800 K were measured. Measurements of the decomposition rate of N2H4 behind reflected shock waves with an excess of He were extended up to 1550 K. Evaluation of the half-lives indicated that the rate of decomposition does not depend upon the nature of the carrier gas.
