Interpretive Summary:

Technical Abstract: Vegetable oils are already used as lubricants because of their superior lubricity, good anticorrosion properties, better viscosity-temperature characteristics and low evaporation losses in industrial applications of rolling, cutting, drawing and quenching operations, either alone or in combination with mineral oils. These oils are readily biodegradable and environmentally safe compared to mineral oil, as they contain readily biodegradable constituents such as fatty acids. From the environmental aspect, their importance is evident, especially in the areas of total-loss lubrication, military applications, and in outdoor activities such as forestry, mining, railroads, dredging, fishing and agriculture hydraulic systems. However, extensive VO use is restricted because of their poor cold-flow behavior and low thermo-oxidative and hydrolytic stability, which can be mitigated by suitable modifications to the oil structure. Modification of the oil through chemical processing to improve oxidation stability and low temperature fluidity is still a subject under active investigation. Different modification routes will be covered in this chapter.
