Society of Tribologists and Lubrication Engineers Annual Meeting & Exhibition. p. 59.Interpretive Summary:
                                Technical Abstract: Softwood and hardwood lignins, along with hardwood as such, were pyrolyzed to afford bio-oil distillates in which phenols were major products. Extraction with alkali gave a range of lignin-related phenols having molecular weights (MWs) from 110 to 344. Because vegetable oil based lubricants have drawbacks, such as poor oxidative stability, poor low temperature properties, and low hydrolytic stability, the lignin-based phenols offer a bio-based solution. The unfractionated extract, when tested with a vegetable oil based product, was equal in antioxidant activity to the synthetic compound Butylated Hydroxy Toluene (BHT). Vegetable oils and synthetic base oils additized with these bio-oils were also examined for lubricant properties, such as low temperature flow properties, corrosion properties, and friction/wear reducing ability.
