Currently, the production of synthetic aromatic compounds in Kazakhstan is not fully established, and the country is forced to import them from abroad. This hinders the development of the perfume and cosmetic industries and increases dependence on external markets. Therefore, the use of economically efficient and innovative methods for producing aromatic compounds is an especially relevant task.

The project, conducted under the guidance of researchers at 91��ý Kazakh National University, aims to develop a technology for synthesizing new aromatic compounds by obtaining complex esters of carboxylic acids using olefins (alkenes, alkynes, and alkadienes), carbon monoxide, and alcohols. This process involves metal-complex catalysts. The catalysts used in the project are modified, heterogeneous, and sometimes possess magnetic properties, which allows them to be easily separated from the reaction mixture and reused.

Complex esters are the main components of modern aromatic compounds. Traditional methods involve reacting organic acids with corresponding alcohols, but this approach is characterized by long process times, low yields, and large amounts of industrial waste. The new method proposed by the project — hydroalkoxylcarbonylation — is carried out as a one-step process, providing a product yield of 95–98% and ecological efficiency. The use of olefins and carbon monoxide as feedstock contributes to environmental protection, reduces industrial waste, and aligns with the principles of green chemistry.

Within the project, scientists synthesize new modified catalysts to replace conventional Pd(II) catalysts. These catalysts ensure high selectivity and reaction rate and can be easily separated from the reaction mixture for reuse. The synthesized aromatic compounds are intended for use in perfumery, cosmetics, and household chemical products. During the research, physicochemical methods such as gas chromatography, mass spectrometry, IR, and NMR spectroscopy are applied, while organoleptic properties and fragrance stability are evaluated through specialized tests. Toxicological studies are conducted to ensure the safety of the products for humans.

The scientific novelty of the project lies in developing a technology for synthesizing complex esters of carboxylic acids using olefins, carbon monoxide, and alcohols, as well as improving production efficiency through catalyst modification. The method is a one-step process using readily available reagents, achieving high product yields while being environmentally friendly. Additionally, the technology allows for the production of domestic products for Kazakhstan’s perfume industry, reducing dependence on imports and contributing to the creation of new jobs.

The practical significance of the project is considerable. Commercialization of the synthesized aromatic compounds can help saturate the domestic perfume and cosmetics market, providing a concrete example of applying scientific results in industrial production. The research outcomes can also be incorporated into the university’s curriculum, enabling the launch of a new master’s program in “Chemistry of Perfume and Cosmetic Production.” This will contribute to the development of chemical education and scientific potential in Kazakhstan, train new specialists, and enhance the quality of the perfume industry.

The project not only strengthens the country’s scientific and technical potential but also promotes environmentally and economically efficient production, reduces import dependence, and allows the manufacture of modern aromatic compounds using new technologies. Its results reinforce the position of Kazakh scientists in the international scientific community, support the development of the perfume and cosmetic industries, and provide high-quality and safe products to the population. The significance and novelty of the project make it one of the leading directions in chemical research in Kazakhstan and play a crucial role in training the next generation of chemists.
