Abstract

The paper analyzes and generalizes the information available on animal fats that can be used as secondary raw materials in production of lubricants compatible with the new recycling technologies. The paper reviews the current market of lubricants, analyses the environmental problems in manufacturing of petroleum-based lubricants and suggests a new class of alternative raw materials for the lubricant production. The experimental studies showed that sunflower oil contains the highest number of unsaturated bonds as compared to other fats. The iodine number measurements of the beef and chicken fats indicated that the latter contains more unsaturated carboxylic acids. Dynamic viscosity of the beef fat is much higher than that of other studied fats. The synthetic acylglycerols have higher temperature-dependent and shear viscosity as compared to the original fats. The paper presents the results of experimental physicochemical and rheometric studies of animal fats. It is shown that animal fat-based materials may serve as an alternative source of environmentally-friendly lubricants.
