Procedures for qualitative and quantitative analysis of microimpurities of alkylhydrazines and their transformation products in hydrocarbon rocket propellants Naftil, Syntin, and Detsilin by gas and liquid chromatography with on-line and off-line mass-spectrometric detection were developed. Reliable detection of an unsymmetrical dimethylhydrazine impurity in Naftil multicomponent propellant and in its mixtures with other hydrocarbon propellants is possible in the form of thiosemicarbazides by reversed-phase high-performance liquid chromatography and matrix-assisted laser desorption/ionization mass spectrometry.

The neutralization of toxic hydrazine fuel accidents and spills is an urgent task of protecting the biosphere. The effectiveness of using shungite for sorption and catalytic destruction of unsymmetric dimethylhydrazine and its transformation products in the environment has been established. The interaction of shungite with unsymmetric dimethylhydrazine that has fallen into water and soil is investigated. The composition of the products of oxidative transformation and desorption was identified, and the kinetics of changes in their concentration on the surface of various sorbents was studied depending on the state of the environment and temperature, soil composition and the presence of shungite. According to the results, a technology has been created that allows efficiently and environmentally sound elimination of spills of hydrazine fuel. The reliability of this technology is based on the results of chromatographic and mass spectral methods for monitoring the neutralization degree of ecotoxicants.

Thermolysis of low and high molecular aliphatic carboxylated compounds in composite systems based on nanosized aluminum were studied by the thermal desorption mass spectrometry. The conditions for maximal separation of the thermolysis products and their composition were determined. The kinetic parameters of thermal desorption and thermal degradation of the modifiers were calculated. Differences in the thermal stabilities of the polymer composites based on nanosized aluminum and different modifiers (carboxylated divinyl and divinyl nitrile oligomers) were presented.
