THE RADIOLYTIC DECOMPOSITION OF 1,1DIMETHYLHYDRAZINE, DIETHYLENETRIAMINE AND HYDYNE ROCKET FUELS,

Abstract

One hundred-milliliter samples of the storable liquid rocket fuels, 1,1-dimethylhydrazine, diethylenetriamine, and Hydyne generate respectively 199.0, 101.2 and 164.1 ml of radiolytic off-gas (measured at 25C and 1 atm) when irradiated to 8,500,000 rads with gamma rays. The result for Hydyne was calculated from those for 1, 1-dimethylhydrazine and diethylenetriamine, Hydyne consisting of 60 wt-% of the former and 40 wt-% of the latter. When the samples contain 5 vol-% of the freeradical scavenger methyl methacrylate, the off-gas volumes are reduced respectively by 18.2, 11.0 and 16.7 %. Since the free-radical scavenger reduces somewhat the off-gas from the fuels due to laboratory ionizing radiation, it may be expected to improve their storability somewhat with respect to ionizing space and nuclear rocket radiations.
