1. Patent filed on a boron-containing lubricant additive. Many lubricant additives require the use of undesirable phosphorous, zinc, and sulfur in order to be effective. Additionally, they are often incompatible with bio-based lubricants. ARS scientists in the Bio-Oils Research Unit at the USDA-ARS National Center for Agricultural Utilization Research (NCAUR), Peoria, IL, in collaboration with an industrial partner, have synthesized and filed for a patent on a new family of lubricant additives. These additives are made primarily from organoboron compounds prepared by utilizing epoxidized soybean oil. From this research, an antiwear and an antioxidation additive have been made, and they show high effectiveness even in soybean oil-based lubricant formulations. This work will help in the creation of new bio-based lubricants which will perform in a wide variety of industrial applications.
