Signals for water occur at different frequencies in 1 H NMR spectra depending on the solvent used ... Acetone 2.8 Acetonitrile 2.1 Benzene 0.4 Chloroform 1.6 Dimethyl Sulfoxide 3.3 Methanol 4.8 ...
A methanol-to-oil ratio of 40:1 yielded the highest conversion under mild conditions. The 1 H NMR spectrum of the resulting biodiesel confirmed a 99 % yield, consistent with results obtained using ...
