—Biodiesel was produced by microwave-assisted
transesterification of soybean oil with methanol as esterifying
agent and sodium methoxide as catalyst. Fourier transform
infrared spectroscopy was employed as a fast and reliable
analytical technique for the quantification of fatty acid methyl
ester content in the produced biodiesel. The quantification was
done with the use of a partial least squares model developed
based on the infrared spectra obtained. It was shown that
microwave irradiation is capable of reducing the reaction time
when compared to conventional mechanically stirred reactors
used for biodiesel production. In addition, quantification of fatty
acid methyl ester content in biodiesel by Fourier transform
infrared spectroscopy coupled to multivariate statistics was
—Biodiesel, microwave, FTIR.
