Description
Summary:The products of conversion of 1,1-dimethylhydrazine after contact with the surface of AMg-6 alloy, which is a model of construction materials that contact with rocket fuel components, were characterized by use of chromatographic and mass-spectrometric methods. Alkyl phthalates, the homologues of triphenyl phosphate, and numerous polymer-homologues related to acetone condensation products were detected in acetone extracts taken from the test surfaces. The presence of such products makes it possible to identify fuel components that contacted with the construction materials; this is important for the utilization of the detachable parts of launch vehicles.
