Abstract:

The fate of chemicals in aqueous environments is determined by diverse processes chemical degradation, physical phase transfer, and dilution or dispersion. The study focused on the uncatalyzed aqueous decomposition distilled, sea, and pond water of hydrazine fuels. Despite their hypergolic nature, these fuels are remarkably stable in uncatalyzed aqueous solutions. Monomethylhydrazine MMH and unsymmetrical dimethylhydrazine UDMH were found to be extremely stable in distilled water, and had slow half-lives 10-14 days in ponds and seawaters. As this study minimized biological decomposition and phase transfer losses, the aqueous half-lives of 10-14 days are very conservative figures and represent worst case situations. Author
