Characterization of Fatty Acid Methyl Esters From Oils With Different Origins Using Fourier Transform Infrared Spectroscopy

Abstract

The fatty acid methyl esters (FAME) of triglycerides obtained by transesterification reaction in the presence of alkaline catalysts became a serious alternative of fossil fuels. In the present research FAME synthesized from five different in their chemical nature and composition vegetable oils were studied. The data for analysis and characterization of FAME was obtained using fourier transform infrared spectroscopy and then basic properties of biodiesel fuels were determined. The confirmation and validation of the results were proved by classical chemical methods of analysis. The ability for express analysis of biodiesel fuels by IR spectroscopy was confirmed and the achieved results are reliable basis for the biofuels stability research.
