Abstract

The article is dedicated to the development of processes for (oligo)alkylation of petroleum fractions rich in aromatic hydrocarbons, with α-olefins (hexene-1, octene-1, decene-1) in the presence of ionic-liquid catalytic systems and the study of the properties of the products obtained. Alkylation reactions were carried out in the presence of chloroaluminate ionic liquids; for the first time a (nano)metal-polymer composite (NMPC) was used in the catalytic system as a modifier, and zinc chloride (ZnCl₂) was used in the catalytic system as a component and the results were compared. It has been shown that these ionic liquid catalytic systems (ILCS) are suitable for (oligo)alkylation reactions and the use of these additives in their composition will lead to efficient alkylation. The products obtained were analyzed by IR-, NMR- spectroscopy, fluorescent indicator adsorption methods, and size exclusion chromatography. It was shown that these petroleum fractions rich in aromatic hydrocarbons can be used as alkylation components, and depending on the composition of the ILCS, it is possible to regulate the molecular, thermophysical and other characteristics of the products obtained based on them. The alkylated products obtained have been tested as plasticizing additives in polyolefin composites.

离子液体催化体系下富含芳烃的油分与C6、C8和C10 α -烯烃的烷基化反应

本文研究了在离子-液体催化体系下，用α-烯烃(己烯-1、辛烯-1、癸烯-1)催化富芳烃石油馏分(低聚)烷基化的工艺，并对所得产物的性质进行了研究。在氯铝酸盐离子液体存在下进行烷基化反应;首次将(纳米)金属-聚合物复合材料(NMPC)作为改性剂应用于催化体系，并将氯化锌(ZnCl2)作为组分应用于催化体系，比较了改性效果。研究表明，这些离子液体催化体系(ILCS)适用于(低聚)烷基化反应，在其组成中加入这些添加剂将导致高效的烷基化反应。所得产物采用红外光谱、核磁共振光谱、荧光指示剂吸附法和排阻色谱法进行分析。结果表明，这些富含芳香烃的石油馏分可以作为烷基化组分，并且可以根据其组成来调节其产物的分子、热物理和其他特性。所制得的烷基化产物作为聚烯烃复合材料的增塑剂进行了试验。
