Technical Abstract: In this decade, great interest has been stirred up toward the use of renewable resources as industrial fuels, such as bio-ethanol and bio-diesel. Bio-lubricants are also playing a more prominent role and becoming competitive with petroleum-based lubricants. The main draw here is that we can, from year to year, grow the crops from which the feedstock is generated for these materials in contrast to non-renewable mineral sources. Added to their renewability is biodegradability of the end-use products after their useful lifetime. In a recent study of the tribologic characteristics of modified Milkweed oil, the derivatives were found to exhibit good oxidative stability as well as excellent anti-wear properties. To further improve the oxidation stability of such materials in lubrication applications and in other uses, we have replaced the -C-O- bonds of the derivatives with -C-N- bonds which are expected to be more stable to oxidative stress. Data resulting from evaluation of these substances will be discussed.
