Technical Abstract: Biodiesel is usually analyzed by the various methods called for in standards such as ASTM D6751 and EN 14214. Nuclear magnetic resonance (NMR) is not one of these methods. However, NMR, with 1H-NMR commonly applied, can be useful in a variety of applications related to biodiesel. These include monitoring of the transesterification reaction that produces biodiesel and related quality issues, determining the fatty acid profile to a large extent, assessing the oxidation status, and verifying levels of blending with petrodiesel. These issues, including a comparison to those prescribed in standards, will be addressed.
