The volume of the catalytic cartridge was kept constant in all experiments, though in case of MFC the mass amount of the catalyst in this volume was much lower (less than 150 g per l of the bed) than that for the conventional catalysts.The observed dependence of the apparent reac-tion rate upon temperature for different types of the catalyst packing is given in Fig.1. Comparison was made for temperature region above 200 °C, where the reaction was limited by the external mass trans-fer. It is seen that the MFC in the form of cartridges with corrugated structuring wire mesh demonstrates the excellent volume performance competitive to that of the monolith catalyst (Fig.1a). At the same time, all MFCs look much more efficient than con-ventional catalysts in terms of apparent reaction rate per unit catalyst mass (Fig.1b). MFCs may be ap-plied for intensification of many catalytic processes. acknowledgements The work was performed within the frame-works of the joint Research and Educational Center for Energy Efficient Catalysis (Novosibirsk State University, Boreskov Institute of Catalysis) and State Research Task Program (project No.V.46.5.6), supported by Russian Academy of Sciences and Federal Agency of Scientific Organizations.references1.

SakhnevichNational Research Tomsk Polytechnic University 634050, Russia, Tomsk, 30 Lenin Avenue, bogdanov_ilya@mail.ruDiesel is one of the most popular types of mo-tor fuel. Currently, diesel fuel is an important part of Russian transport system because most of the trucks and agricultural vehicles consumes diesel [1].Basic physico-chemical and operational prop-erties of diesel fuel produced in Russia are gov-erned by three basic standards: USS 305-82, USS R 52368-2005 and Technical Regulations of the Cus-toms Union "Requirements for automobile and avi-ation gasoline, diesel and marine fuel, jet fuel and heating oil". The most stringently controlled char-acteristics of diesel fuel are: cetane number, flash point, density, kinematic viscosity and low tem-perature properties (cloud point, cold filter plugging point, pour point).Cetane index is the most important character-istic of diesel fuel used in internal combustion en-gines. Optimal performance of modern engines is achieved by using of diesel fuel with a cetane index from 45 to 55 points. If cetane index of diesel fuel is less than 45 points, the combustion delay (the time between the beginning of fuel injection and its igni-tion) is increased, and the pressure rate in the com-bustion chamber rises, thereby engine wear is in-creased. If cetane index is higher than 55 points, the combustion efficiency is reduced, and smokiness of diesel fuel as well as its consumption rises [2].Experimental determination of cetane index is a multi-step and time-consuming process. That is why determination of cetane index in this study was performed using calculation methods. Allthe calcu-lations were carried out basing on the international standard ISO 4264 where cetane index is calculated by the following equation:CI = 45.2 + 0.0892 • T10N + (0.131 + 0.901B) • T50N + + (0.0523 – 0.42B) • T90N + + [0.00049 • (T210N – T290N)] + 107B + 60B2;T10N = T10% – 215; T50N = T50% – 260; T90N = T90% – 310; XVII Международная научно-практическая конференция имени профессора Л.П. Кулёва496B = [exp(–0.0035 • DN)] – 1; DN = D – 850.CI – cetane index, points; Т10%, Т50%, Т90% – boiling point of 10%, 50%, 90% fraction, °С; D – fraction density at 15 °С, kg/m3.For this study, 5 diesel fuel samples were pur-chased at various filling stations in Tomsk. Samples were assigned with numerical codes. Fractional composition of purchased samples was determined experimentally using laboratory device of fractional distillation (Table 1).Purchased samples were then checked for the compliance with USS R 52368-2005 "Fuel diesel Euro. Specifications" by such parameters as density and cetane index. The results are presented in Ta-ble 2.It was found that all purchased samples meet the requirements in terms of cetane index . Howev-er, it can be seen from Table 2 that samples No. 2, 3 do not meet the requirements for density.references1.

For instance, vanilloloside 1 was isolated from Nelumbo nucifera stamens [1], and others, and has specific activity against cancer cells, such as HeLa (cervix cancer) and MCF-7 (breast cancer) [2], and is efficient at inhibiting fermentative activity of ace-tylcholinesterase and, thereby, could potentially be utilized to cure Alzheimer [1]. Calleryanin 2 was isolated from Pyrus Calleryana leaves and shows scavenging and antioxidant activity [3]. Its deriv-ative 7-O-trans-caffeoylcalleryanin 5 was isolated from P. Calleryana [5] and may have the similar ac-tivity.On the first step of the synthesis we performed glycosylation of vanillin 1a and protocatechuic al-dehyde 2a with acetobromoglucose (ABG) in two different systems. Obtained aldehydes 1b and 2b were reduced with NaBH4 in conditions of phase table 1.
