Oil is one of the most important mineral resources. However, oil refining is harmful to the
environment. Currently, the task of finding new effective catalysts for petrochemical and organic
synthesis processes that meet the requirements of "green chemistry" is an urgent task in
Kazakhstan. To solve this problem, the Kazakh doctor of science Khadichakhan Rafikova created a
new type of rhodium-iridium catalysts used in oil refining processes.
The creation of rhodium-iridium catalysts based on phosphorus-containing ionic liquids is a
completely new direction in the scientific field of Kazakhstan. An ionic liquid is a special class of
salts, consisting only of ions and having a melting point below 100°C. They are mainly used in
applied sciences, biotechnology, energy and petrochemistry. Ionic liquids are called green solvents.
The relevance of this topic lies in the use of rhodium-iridium catalysts in processes important for
industry and petrochemical synthesis, such as the hydrogenation of acetophenone, the co-production
of styrene and propylene oxide from ethylbenzene and propylene, the production of stilbenes
necessary for semi-rigid plastic production by copolymerization with more active monomers.
The fundamental difference is that generally harmful acids are used as solvents in the process
of oil refining. These standard solvents are very harmful to the atmosphere, being one of the reasons
for the formation of ozone holes, which leads to global warming. Whereas rhodium-iridium
catalysts allow the process to be carried out without these solvents, on the basis of water - the purest
and most environmentally friendly reagent.
