Abstract

The aim of the study is to synthesize hetaren derivatives of acetylene amination reactions using local natural raw materials as catalyst carriers. Various grades of Oltintag and Angren kaolins, various grades of Navbakhor bentonite, as well as the opaque rock of the Karmaninsky deposit were used as catalyst carriers. Thermal, acidic and hydrothermal treatment was carried out on the appropriate sorbents, with the production of catalysts of various modifications from sorbents and active components. The processes of catalytic condensation of acetylene with ammonia were studied using modified catalysts. The effect of the reaction temperature, the active components of the catalyst, and peptizers on the product yield has been studied. A hypothetical mechanism of formation of getarenes from acetylene is proposed. It is determined that the optimal synthesis temperature for getarene derivatives is 420 ^oC. The total yield of picolines in reactions involving the most active CCCOR catalyst was 81%.
