Synthesis of complex oxypropylated 1,2(cyclohex-4-en) diacetic acid and investigation of them as lubricanting oils_______________17-21
Keywords: esterification reaction, cyclic diacetic acid, low-viscosity lubricating oils, operational properties.
Abstract. A number of esters of oxypropylated 1,2 (cyclohex-4-ene) diacetic acid (CHDAA) with aliphatic alcohols C4-C8 were synthesized and their physicochemical, viscosity-temperature, thermooxidative (TOS) properties and application possibilities of the obtained compounds as lubricating materials were studied. The structures of synthesized compounds are confirmed by IR and NMR spectroscopy methods, as well
as the determination of molecular weight, acid and ether numbers. The obtained esters are colorless liquids with a high boiling point. Data on molecular weights correspond to those calculated, their yield is 83-92% by weight from the theoretical. The synthesized esters have an average viscosity level at 100°С (4.80-6.12 mm ГОСТ 23797-79 in the volume, corrosive aggressiveness on the plates of the aluminum 2/s), high flash points
(225-275°С) and a viscosity index (130-140 units), low pour points (negative 40 — negative 50°С) and viscosity at -400C (2200-3800 mm2/s). The thermo-oxidative stability of the esters was determined in accordance with alloy AK-4 and steel ШХ-15 during oxidation of 30 g. diesters with air (air feed rate-50 ml / min, 200°С, 10h).
After oxidation, the viscosity of the esters at 100°C increases from 4.95 to 6.44mm2/s, the acid number is from 3.42 to 5.28 mgKOH/g. The sediment is insoluble in isooctane 0.013-0.044%, evaporability 0.40- 0,76% by weight. There isan insignificant corrosion of the aluminum alloy AK-4 (0.015-0.056mg/cm2) and steel ШХ-15 (0.039-0.076mg/cm2).
When comparing the hydrogenated ethers of oxypropylated CHDAA with the corresponding unhydrogenated ones, it was revealed that they differ little from each other. This is explained by the fact that in this case the double bond is in a cycle, behaves inertly, which has an insignificant effecton the properties of the ethers.
When comparing the results of viscosity-temperature and TOS of ethers of hydroxypropylated CHDAA and the requirements for oils 36/1 КУ «А», it is established that the synthesized esters in allindices are not inferior to the specified oil.
Thus, the study of diesters of oxypropylated 1,2(cyclohex-4-ene) diacetic acid as base lubricating oils showed that they have good viscosity-temperature properties at positive and negative temperatures,as well as good thermo-oxidative characteristics, meet the requirements for low viscosity aviation oils,in particular to oil 36/1 КУ»A» and can be offered as its replacement.

Alkylation of phenol by methyl ethers of cyclohexencarbonic acidin the presence of phosphorush containing zeolite_____________________________21-26
Keywords: phenol, methyl esters of cyclohexenecarboxylic acid, phosphorus-containing zeolite, cycloalkylation, Claisen rearrangement.
Abstract.The reactions of cycloalkylationofphenol with methyl esters of cyclohexenecarboxylic acid in the presence of aphosphorus-containing zeolite-Y catalyst were studied.The reaction was carried out as follows:the calculated amount of phenol, methyl esters of cyclohexenecarboxylic acid and zeolite- Y catalyst, impregnated with orthophosphoric acid, is loaded into at hree-necked flask equipped with a stirrer, thermometer and dropping funnel and heated. When the temperature reaches 40°C, we gradually introduce the required amount of ether into the flask from the dropping funnel. The resulting mixture of components in the presence of the catalyst is heated and at a temperature ofT = 80-120°C with stirring for 2-6 hours. After cooling the mixture atT=45°C, the catalystis separated by filtration ofthe reaction mixture. Then a mixture of rectification was subjected. During distillation, the ether and phenol (up to200°C), which were not included in the reaction, were distilled off at atmospheric pressure, and then the target reaction products were isolated at low pressure (5 mm Hg) and their purity and physicochemical parameters were determined. The structure and composition of the desired products(methyl 4-(4-hydroxyphenyl)-and 4-methyl-(4-
hydroxyphenyl) cyclohexanecarboxylic acids) were determined by 1H NMR-and IR-spectroscopy. In order to find the optimal conditions ensuring the maximum yield of the target products, the effect of temperature, reaction time, phenol molar ratio to ether, the amount of catalyst at the outlet and the selectivity of the reaction products. It was found that under optimum conditions the yield is 74.3-77.8% of the theory forthe phenol taken, and the selectivity forthe target product is 94.6-95.2%.

Among them
especially should be noted catalytic cracking processes, hydrofluoric alkylation and diesel fuel hydrotreating. This fact causes first priority of carrying out optimization actions for these processes. In this work the analysis catalytic systems operation on LCh-24/2000 and L-24/7 diesel fuel hydro treaters is carried out. The results received during research can be used for practical implementation at the enterprises PAO «Lukoil» and the similar enterprises of other oil refining companies that will allow to optimize mode and to increase energy efficiency of hydrotreating process of diesel fuels. Mathematical processing and the regression analysis of statistical data of work of hydrotreaters with use of complex of the differential equations describing operation of the reactor of ideal replacement is carried out. Empirical dependences are defined and on its basis the system of operational monitoring of hydrotreating catalytic systems activity, including the function of process optimal temperature calculation is developed. The solutions proposed allow to reduce inertance of hydrotreating control due to timely
forecasting of optimum temperature in hydrotreating reactors. The developed system of catalytic systems activity monitoring allows to increase economic efficiency of
management decisions, in particular:
• to carry out assessment of duration of catalytic systems operation cycle, hydrotreating of diesel fuel that will allow to plan more precisely the shutdown date of facilities for repair during which catalyst replacement is carried out;
• to predict the process optimum temperature that will allow to reduce hydrotreating duration, and as a result will reduce power consumption of the unit and will provide decrease in deactivation of the catalyst;
• if necessary to carry out adjusting actions on the directions the difficult processed components of raw materials to the unit with more active catalytic system that will allow to operate the LCh-24/2000 and LCh-24/7 on the maximum loading on raw materials with preservation of required duration of cycle of catalytic system.
