THE USE OF RAPESEED OIL AS A DISPERSION MEDIUM FOR ALTERNATIVE LUBRICA

Background. Due to the intensive development of the oil industry with the emergence of new sources of pollution, the relevance of environmental issues has increased dramatically. Therefore, the development and implementation of biodegradable lubricants is a promising direction of development of the world petrochemical industry. The leading role in solving this problem belongs to bioresources – vegetable oils, especially rapeseed oil and products of its transesterification, which are an acceptable alternative to oil raw materials for the production of lubricants. Purpose. Development of environmentally friendly lubricants with increased biodegradability from local raw materials. Determination of their physical, chemical and operational characteristics. Methodology. Comparative physical and chemical parameters of motor and biodegradable oils were determined according to TU TSh 39.3-199:2003. The IR spectra of rapeseed oil and nigrol were analyzed on a SHIMADZU spectrophotometer. The qualitative and quantitative content of chemical elements, the elemental composition of finely divided graphite substances after the second flotation purification were determined by X-ray fluorescence analysis. Originality. A new composition of lubricants with enhanced performance and biodegradability, competitive with foreign counterparts, has been developed. Significant scientific and practical interest are the raw materials and technological capabilities of local industries, including oil refinery, oil and fat factory. Findings. The composition of biodegradable motor oil based on rapeseed oil was obtained using finely divided graphite from the second flotation purification of graphite ore with a carbon content of 31% as an additive. Highlights: * physical and chemical characteristics of rapeseed oil were determined; * a composition of motor oil based on rapeseed oil was obtained; * comparative physical - chemical characteristics of motor and biodegradable oils are given.
