The character of the mutual interaction of the components in the CuI-SbI3 system was studied by differential thermal analysis and X-ray phase analysis methods and its phase diagram was constructed. It was found that the system is quasi-binary and forms a monotectic phase diagram. The immiscibility region covers ~15-93 mol% SbI3 concentration interval at the monotectic equilibrium temperature (~ 4930С). The temperatures of polymorphic transformations of the CuI compound in the system drop slightly and these phase transitions take place by metatectic reactions

The phase equilibria in the Cu-Sb-S-I quaternary system were studied by differential thermal analysis and X-ray phase analysis methods in the CuI-SbSI-SbI3 concentration intervals. The boundary quasi-binary section CuI-SbSI, 2 internal polythermal sections of the phase diagram, as well as, the projection of the liquidus surface were constructed. Primary crystallisation areas of phases, types, and coordinates of non- and monovariant equilibria were determined. Limited areas of solid solutions based on the SbSI (b-phase) and high-temperature modifications of the CuI (α1- and α2- phases) were revealed in the system. The formation of the α1 and α2 phases is accompanied by a decrease in the temperatures of the polymorphic transitions of CuI and the establishment of metatectic (3750C) and eutectoid (2800C) reactions. It was also shown, that the system is characterised by the presence of a wide immiscibility region that covers a significant part of theliquidus surface of the CuI and SbSI based phases

The article examines the methods of preparation of low-freezing oils. Due to their high viscosity-temperature properties, ethylene-hexane oils are used in industrial compressors, vacuum, etc. can be used as oils. sooligomerization of ethylene with 1-hexane in the presence of a catalytic system in an intermittent apparatus (Al + IPX + C 2 H 4 ) was studied. This catalyst accelerates the process of sooligomerization of ethylene with 1-hexane and an oil-type oligomer is obtained. The effect of various parameters (temperature, reaction time, amount of IPX (isopropyl chloride) in the reaction zone and ethylene in the liquid phase) on the process and the characteristics of the fat fraction was studied, optimal conditions for the synthesis of a good oil base were determined. When studying the effect of temperature on the process of so oligomerization of ethylene with 1-hexane in the range of 80-150 0 C, it was found that the induction period for the formation of the active catalytic complex decreases sharply: from 120 minutes to 3 minutes. However, there is an increase in the total yield of oligomeric products and their fat fractions. It was determined that the optimal temperature for the production of oils with viscosity-temperature properties is 100-120 0 C. Above this temperature, the properties and quality of the oil deteriorate. At temperatures of 80 0 C and below, sooligomerization reactions proceed very slowly. As the content of IPX increases, the formation time of the catalytic complex decreases sharply, the reaction rate and the total output of the salinometer increase, the yield per 1 g of IPX decreases per minute. However, more than 10 g / l in the reaction zone of IPX has a negative effect on the properties of fat fractions. Thus, rational conditions for the application of oils have been identified. It has been determined that the oils obtained can be used as medicinal and perfumed oils.
