Main scientific achievements  A complex scheme of obtaining various surfactants based on carboxylic acids, higher alkanols, aliphatic amines, epoxides and aminoalcohols for application in oil industry has been developed.

In recent years systematic studies in the field of synthesis of ionic liquid compositions are conducted which finds wide application as a catalytic component, catalytic systems and reaction medium and solvent allowing creation of simple, ecologically safe, economically effective technologies of synthesis and processing. In particular, synthesis of chloroaluminate ionic liquid catalytic systems has been carried out. Oligomerization of C8-C10 α-olefins in their presence has been realized giving synthetic poly-α-olefin oils characterizing by high viscosity, viscosity index, low unsaturation degree, freezing point, oxidation stability and low volatility. By studying the structures of synthesized oil fractions it has been found that oligomerization of α-olefins in the presence of chloroaluminate ionic liquids leads to formation of oligomers having naphthene-paraffin structure practically not containing unsaturated fragments in macromolecule that makes possible their use as a component in obtaining semisynthetic base oils without preliminary hydrogenation. Possibility of obtaining semisynthetic engine and industrial oils on the base of synthesized poly-α-olefin oil fractions and mineral oil has been shown.

Purposeful studies has been conducted in the field of selective purification of petroleum fractions using neutral ionic liquids as a selective solvent synthesized on the basis of organic acids and various amines. Perspectives of use of synthesized ionic liquids as an extractant for selective purification with obtaining fuels and base oils of improved quality has been established. Based on obtained results, ionic liquid on the basis of morpholine and formic acid is recommended as an extractant for selective purification of oil fractions of various viscosities. Synthesis of experimental batch of mentioned ionic liquid and purification of transformer oil were realized at experimental-industrial plant.

Extensive research on the synthesis of the alicyclic functional monomers has been investigated; as a result the method of synthesis of new monomers bicyclic, tricyclic, tetracyclic acrylate and methacrylate has been studied and on their base oligomer and polymers have been prepared which are practically extensive.

Reasearches on the synthesis of ion-liquid monomers on the base of (met)acrylic acids and also on polymerization and co-polymerization of them by obtaining a new quality of polymeric products were conducted. Antimicrobial properties of the synthesized ion-liquid monomers and polymers on their base were determined. Absorption capacities of CO2 of these products were established.

Developed simple “in situ” method for obtaining metal-organic catalytic systems which contains "grafted ionic liquid" ligands and prepared polyolefins with various properties in their presence. Investigated esterification reactions mechanisms in the presence of sulfonated derivatives of graft copolymers. Cu-, Fe-, Al- containing polymer nanocomposites and phase- transition materials which is characterized by magnetic and electrical properties and having high physical-mechanical indices and termooxidative stability have been developed. Obtained environmentally and economically efficient recyclable ionic-liquid type extragents on the basis of C4- fraction of pyrolysis and catalytic cracking which allows selective separation high-octane additives from azeotrop mixtures.

Researches on the synthesis of polymers and co-polymers of styrene were conducted. Conditions of the synthesis of polystyrene and co-polymers of styrene with eaters of met-acrylic acid of the resulted structure with narrow poly-disperse were determined.
