Interpretive Summary:

Technical Abstract: The development of fully biobased lubricants requires the application of biobased base oils and biobased additives in the formulation. Such formulation will provide the full environmental, health, safety, and economic benefits expected from replacing petroleum-based products with biobased products. In the past few years, there has been steady progress in the development and commercialization of biobased base oils. Current commercial biobased base oils include: vegetable oils; derivatives of vegetable oils using various chemical/biorefinery methods; and biobased oils from fermentation of sugars. However, the development and commercialization of biobased additives has not been as robust as that for biobased base oils since multiple additives (e.g., antioxidant, anti-wear, etc.) are required for most formulations. As a result, most current biobased formulations are developed using commercial petroleum-based additives. Such formulations are partially biobased and not capable of providing the full benefit of a fully biobased formulation. In this presentation, recent work on the synthesis and characterization of a new biobased disulfide additive from soybean oil will be discussed.
