Technical Abstract: Biobased lubricants are of great interest because they are produced from renewable farm-based raw materials and have the potential to provide a positive impact to the environment. However, realizing the full potential of biobased lubricants requires that the formulation be comprised exclusively of biobased base oils and additives. Currently, there is a very limited number of commercial biobased base oils that formulators can choose from for their formulations. The situation is even worse when it comes to biobased additives. As a result, most formulators are forced to experiment with and use commercially available petroleum-based additives in their products. While this approach has allowed the development of well performing biobased commercial lubricants that meet the bio-content standards for some applications, the goal of fully biobased formulations has yet to be attained. In an effort to help with this goal, our group is engaged in the development of biobased additives. In this presentation, we discuss the synthesis and tribological characterization of polyphosphonated vegetable oils and esters. These products have displayed a number of interesting additive properties including anti-wear characteristics comparable to commercial zinc dialkyldithiophosphate (ZDDP).
