Title : Sustainable development of eco-efficient lubricants: Synthesis of polymer-based modifiers and synthetic fatty acids from local hydrocarbon resources
Abstract:
Rapid industrial transformation and increasing ecological challenges demand the development of environmentally compatible and high-performance lubricating materials. This research focuses on the sustainable synthesis and application of eco-efficient lubricant components obtained from local hydrocarbon resources of Uzbekistan. The study integrates two complementary scientific directions: (i) the production and characterization of synthetic higher fatty acids (SHFAs) derived from secondary hydrocarbons through controlled oxidation processes, and (ii) the synthesis of advanced heteropolymer-based viscosity modifiers (SURKOV-type materials) designed to improve thermal stability, oxidative resistance, and rheological properties of modern lubricants.
Synthetic fatty acids produced from local feedstocks demonstrate favorable biodegradability, improved lubricity, and reduced toxicity compared with imported petroleum-based analogues. Simultaneously, newly developed polymeric modifiers—based on epoxy-polyester and heterocyclic monomer systems—exhibit superior thickening efficiency, shear stability, and compatibility with mineral and synthetic oils. The synergistic integration of SHFAs with heteropolymer additives provides a novel approach for formulating low-emission, energy-saving lubricants that comply with international environmental standards.
The results contribute to sustainable material science by reducing dependence on imported raw materials, lowering ecological impact, and promoting circular use of secondary hydrocarbons. The proposed technology offers significant industrial potential for automotive, mechanical engineering, and chemical sectors. This work aligns with global priorities on green chemistry, waste minimization, and sustainable innovation
