Research Area
Investigations of the structure of flames of gaseous and condensed systems
(CS) including high energetic materials, kinetics and mechanisms of gas-phase
reactions and thermal decomposition kinetics of CS, and simultaneous development
of molecular beam mass spectrometry probing of flame for this purpose.
Research Activities
Development of the methods involving mass spectrometric studies of flame structure of gaseous and condensed systems including fast burning high energetic materials. Together with the Special Technological Bureau of Scientific Instrumentation, Siberian Branch of the RAS, three generations of original installations were created. These set-up units involve molecular beam sampling from the flames of high energetic materials (HEM) and from gas flames stabilised on a flat burner within working pressure range 0.1 – 70 atm. One of the units based on the quadrupole mass spectrometer with soft ionisation by electron impact with electron energy spread within ± 0.15 eV allows also to detect atoms and free radicals in flames. Another set-up allows to study fast combustion processes (within a fraction of a second) detecting at the same time the sample from flame as a molecular beam by tandem time-of-flight and quadrupole mass spectrometers.
Study of the chemical structure of flames of high energetic materials – ammonium perchlorate, RDX, HMX, ammonium dinitramide and their mixtures. Key intermediate species in these flames have been identified and the reactions responsible for chemical transformations which determine burning rate and are the sources of heat release have been revealed. The results of these studies have been used by Russian and western scientists to develop combustion models for these monopropellants and propellants based on them, to test hypotheses and conceptions of modern CS combustion theories.
Within the recent 8 years, the personnel of the Laboratory studies the
destruction
in flames of organophosphorus compounds(OPC) including dimethyl
methylphosphonate, trimethyl phosphate, diisopropylmethylphosphonate which
are the simulants of sarin, ingredient of chemical weapon. The studies
are performed with the flames stabilised on a flat burner. These studies
are connected with the problem of chemical weapons disposal. These studies
have been carried out for 5 years together with the scientists from Cornell
University, National Institute of Standards and Technology, Sandia National
Laboratories. A large set of intermediate and final phosphorus-containing
products has been identified in H2/O2 flames, together
with other products including H and O atoms, hydroxyl radicals. Concentrations
and concentration profiles of these products have been measured. It has
been revealed that the mentioned OPC promote combustion of hydrogen-air
mixtures and inhibit combustion of methane-air mixtures. A detailed mechanism
of OPC destruction in flames has been developed, as well as the relevant
mechanisms of flame promotion and inhibition. OPC have been found to be
promising additives as fire suppresants and possible candidates to be used
for replacement of halons (such as CF3Br). The production of
the latter has been prohibited by Montreal Protocol because they deplete
ozone layer of the atmosphere. The Laboratory searches for effective OPC
as fire suppressants. Jointly with the New Jersey Institute of Technology,
economical technology of destruction of hazardous pollutants (such as OPC
and others) in exhausts using corona discharge have been developed. It
can be widely used, for example in the technology of the disposal of chemical
warfare agents.
