Physical and Coordination Chemistry of Solutions and Processes in Liquid Phase
Vadim V. Budanov
Doctor of Chemical
Science, Professor of the Department of Physical and Colloid Chemistry,
Meritorious Scientist of the Russian Federation
Professor Budanov is the founder and head of
scientific school in the area of sulphur-containing compounds chemistry and
redox reaction kinetics in liquid phase. A new branch in this field “Kinetics
and thermodynamics of redox processes with organic oxo-compound participation
of sulfur (IV-II) in liquid media” has been created and developed by him and
his coworkers. Physico-chemical bases of synthesis and application of high
effective and selective reducing agents (organic and inorganic derivatives of
sulphoxylic acid) and generalized kinetic models for homogeneous and
heterogeneous processes, involving compounds in question, have been created.
The most important physico-chemical properties of redox systems have been
determined as well.
Fundamental studies of V.Budanov initiated
new trends in technical application of sulfur containing reducing agents in
fabric finishing, at producing chemicals additives for polymers, at chemical
metallization of nitron fibres and in obtaining superpure metal powder. These
results of the studies have been brought into commercial practice at some
industrial enterprises.

Yuri G. Bushuev
Doctor of Chemical
Science, Leading Scientist of the “Chemical Reactions Thermodynamics” Research
Laboratory
Yuri G. Bushuev is an expert in the field
of properties of liquids research by means of computer similation.
The principal works are devoted to properties
of individual liquids and solutions study at submolecular, molecular and
hyper-molecular levels. Yuri G. Bushuev is the author of the original method
for liquids structure research. He has determined the formation regularities of
the oriented water structure.
Yuri G. Bushuev was the first to determine
the set of the characteristic structural elements – polyhedrons which consist
of associated bonds cycles totality forming the water H-bond net. The universal
functional dependencies characterizing the bond net in water and aqueous
solutions have been found. Structural properties and regularities of H-bond
systems establishment in liquid formamide, glycol and N-methylformamide have
been studied. It was exemplified by some liquid systems that the main effect
on the hyper-molecular systems and solvation spheres formation is provided by
the universal intermolecular interactions.

Sergey V. Makarov
Doctor of Chemical Science, Head of
the Department of Food Technology and Biotechnology
The research activity of Sergei V.Makarov
focuses mainly on kinetic studies of sulfur-containing reductants reactions, including
thiourea oxides, as well as on activation of nitrite and inorganic peroxides by
metalophorphyrinates and metalophthalocyaninates. In these studies, such
methods as polarography, UV, IR, NMR and EPR spectroscopy are used.
The systematic studies of stability and
reactivity of α-hydroxitalkane-sulfinates and thiourea
oxides have been conducted. The processes of anaerobic and aerobic
decomposition of thiourea have been studied in detail. The primary product of
these processes – strong reductant sulfoxylate SO2 2- was
shown to be a stable species in alkaline solutions. Its acidic properties were
studied for the first time. Metalophthalocyaninates were shown to be the
effective catalysts of reaction between sodium dithionite and nitrite or
nitrous oxide as well as oxidation of azo dyes by perborate or percarbonate.
The kinetics of the reaction mentioned was studied.
The researches are performed jointly with the
chemists from Erlangen University (Germany).

Professor, Head of General Chemical Technology Department, Vice-rector on
Research Work
V.A. Sharnin is an expert on chemical
reaction thermodynamics and solvation of reagents into different media.

thermodynamics of complexation reactions and reagent solvation. These works are
the foundation for developing scientific principles of the solvent application
as a method for reaction control into liquid phase. The data obtained enable to
predict a direction of chemical equilibrium shift, stability complex changing,
energy and reaction rates when one solvent is replaced by another.
