XVII Международная научно-практическая конференция имени профессора Л.П. Кулёва512Studies were conducted with using process data and the results of tests from the laborato-ry (GC-MS, IR spectroscopy), and specially the developed mathematical model.The analysis of the composition` feed-stock was done and its impact on the quality ABSA was evaluated. It was revealed that the high content of aromatics leads to a decrease alkyl benzene sulphonic acid in the final prod-uct. This is because the high viscosity com-ponents are formed in the sulfonation reactor. Figure shows the dependence of the ABSA`s number from the high-viscosity component.On the next step it is showed the effect on the quality of the finished product from temperature`s feed and the cooling water flowing in the sulfonation reactor. The results of model calculations are presented in the table.It was found that the decrease in temperature is beneficial to ABSA because the number of unsul-fonated residue was decreased.As a result of studies were made recommen-dations on the intensification of production LABS.references1. http://www.acmite.com/market-reports/chemi-cals/global-surfactant-market.html.2.

MatveenkoNational Research Tomsk Polytechnic University 634050, Russia, Tomsk, 30 Lenin Ave., kurtukov@tpu.ruIn the last decades, many researches have been focused on magnetic nanoparticles with different functional groups attached to them. Such materials have a wide range of applications in pharmacologi-cal and medical spheres, such as targeted drug deliv-ery, magnetic resonance imaging (MRI), production of biosensors and catalysis [1]. The scientific group of P.S. Postnikov has developed a new method for synthesis of stable zerovalent iron (ZVI) nanoparti-cles (NPs), coated with aryl groups, using aromatic diazonium salts (ADS) [2]. The process is described in Scheme 1.Now that a reliable synthetic method for pro-duction of nanoparticles was acquired, it was decid-ed to develop a procedure for acquisition of a MRI contrast compound, using aryl-coated AVI NPs as fig. 1.

Gadolinium (Gd) was chosen as a main con-trast agent due to its excellent magnetic properties [3] and ability to form chelates. It was agreed to use diethylenetriaminepentaacetic acid (DTPA) an-hydride to form a strong chelate with Gd because it is fairly easy attached to a free amine group of the ADS. The scheme of a process is shown in Scheme 2.Such substance could become a base for devel-oping new theranostic agent and further research in utilization of ZVI NPs in medical and pharmaceu-tical fields.references1.

Toraigyrov Kazakhstan,  burumbaeva.galiya@gmail.comThe Strategy of the development of the Repub-lic of Kazakhstan until 2030 emphasizes the oil and gas industry, making energy resources a number one priority. This program is the basis for improv-ing the competitiveness of the oil and gas industry of Kazakhstan [1]. Nowadays the Republic of Kazakhstan has three oil refineries – the Atyrau Refinery, the Shy-mkent Refinery and the Pavlodar refinery, for which the increase in the depth of crude oil refining is an urgent task.The aim of this work is to test the kinetic model of the process of catalytic cracking in the Section “C-200” of the installation KT-1/1 of the Pavlodar scheme 1.
