Technical Abstract: Vegetable oils and their derivatives are amphiphilic and display a number of properties critical to their application in tribological processes. Among such properties are: viscosity, viscosity index, oxidation stability, cold flow, boundary friction, etc. The properties of these biobased amphiphiles depend on the exact structures of their lipophilic and hydrophilic components. The lipophilic chain can vary in the number of carbons (chain length), degree of unsaturation, and presence/absence of functional groups on the chain. The hydrophilic head can vary in the type of functional group (e.g., ester, hydroxyl, epoxy, carboxylic acid, etc.), number of functional groups (e.g., mono-, di-, tri-), and location of the functional group. A property (e.g., oxidation stability) of a specific biobased amphiphile depends on the exact combination of the structures of its hydrophilic and lipophilic components. This presentation explores structure-property correlations aimed at predicting certain tribological properties of biobased amphiphiles.
