Background. The growth of industrial production, including oil lubricants, is associated with environmental pollution. In this regard, new requirements for technogenic products are put forward. The article presents the results of studies on the production of environmentally friendly lubricants based on vegetable raw materials – rapeseed oil with increased biodegradability and the use of linseed oil in the composition of lubricants to improve their viscosity-temperature characteristics. The purpose of this work is to study the possibility of obtaining environmentally friendly lubricants and improve their quality characteristics using vegetable raw materials. Methodology. The work used standard methods of analysis (in accordance with GOST) of physical and chemical characteristics of lubricants and their components. Originality. It is established that with a change in the ratio of components of linseed vegetable and petroleum oils, it is possible to obtain a base oil with high viscosity-temperature characteristics by viscosity index. Findings. It has been established that with a change in the ratio of the components of linseed vegetable and petroleum oils, base oils with a high viscosity index can be obtained, which corresponds to the standards and requirements for motor oils of improved quality. Highlights: - ecological characteristics of vegetable and petroleum oils; - biodegradability of rapeseed oil is almost 4 times higher than of petroleum oil; - base oil on vegetable raw materials base.
