Technical Abstract: Biobased oils are those derived from farm-based renewable raw materials. Most are vegetable oils (such as soybean, canola, corn, etc.) or chemical modifications of vegetable oils. They have a number of interesting structural features that impact their amphiphilic and lubrication properties. The basic chemical structure of biobased oils is a triglyceride, or an ester of a long chain fatty acid and fatty alcohol. The presence of one or more ester groups and two or more long hydrocarbon chains (C12 or higher) in the same molecule provides amphiphilic character to the molecules. Polarity also provides biobased oils with tribological properties not attainable with petroleum based oils. Further chemical modification of biobased oils widens the scope of their amphiphilic and tribological properties. This presentation examines the chemical structure of biobased oils and their chemical modifications, and relates it to its amphiphilic and tribological properties.
