Specially formed mixtures of isotopes of chemical
elements have better consumer properties than their
natural counterparts. Therefore, the development of
methods for increasing the efficiency of the known
methods for producing of isotope materials is relevant. It
is known that the chemical bond is formed only in the singlet state of the spins of valence electrons of the
reagents. On the basis of the known representations
about dispersion of spin projections on the coordinate
axes and the molecular-kinetic theory of gases was
obtained an expression for the constant of the chemical
reaction between the radicals occurring in the magnetic
field. This expression allows calculating the reactivity of
the isotopic modifications of radicals. Plasma allows to
transfer many of the compounds in the gas phase. It is
known that a significant part of particles in low
temperature plasma is in a radical form. The equations of
chemical kinetics for describing the process of oxidation
of the carbon isotopes in argon-oxygen plasma occurring
in an external permanent magnetic field were written in
the work. It was shown that the efficiency of plasma
process of isotopes separation can be increased only
under insufficient oxygen relative to the stoichiometric
value. These equations of chemical kinetics of processes
occurring in the plasma process of incomplete oxidation
of carbon isotopes needed to find experimental
conditions that provide the maximum isotope effect in a
magnetic field
The steady increase in demand for isotopes requires the
development of methods to increase the efficiency of
isotope separation technologies. Methods of isotope
separation based on thermodynamic differences of
isotopic forms of the molecules don't require significant
investment, but characterized by a low rate of exchange.
It's known that the magnetic effect leads to a change the
vibrational frequency of the molecules, and therefore
their thermodynamic parameters. The change increases
the thermodynamic parameters, including the exchange
rate. The results of the experimental determination of the
thermal effect of dissolving the salts of NaCl, KCl,
CuSO4, sodium amalgam decomposition by distillate in
a magnetic field and without field were shown. Magnetic
interference can have a significant effect on the amalgam
exchange method which was shown by quantum and
mechanical analysis of the results
