DIFFUSION COEFFICIENT-FORMULA WEIGHT CORRELATION ANALYSIS VIA DOSY NMR TO EXAMINE ACYLGLYCERIDE MIXTURES AND BIODIESEL PRODUCTION

摘要

Biodiesel is a renewable and biodegradable alternative to petroleum diesel. Biodiesel provides nearly four times the energy return as bioethanol while producing significantly less agricultural pollution.The transesterification of waste oil can be monitored by LC- or GC-MS, but chromatograms can be complex. ~1H NMR spectroscopy has been used to examine biodiesel production. However, 1D-NMR methods can have significant signal overlap, and analytes often require derivitization.
