The biodiesel obtained by transesterification by reaction between ester and an alcohol in the presence of catalyst. The purpose
of this work is to evaluate the thermal and kinetic behavior of the methanol biodiesel derived from cotton oil. The quality
analysis was done by gas chromatography and proton nuclear magnetic resonance spectrometry (1H NMR) in order to examine if the product meets with the requirements of the European Standard EN 1403. The thermogravimetric
profile of the cotton biodiesel indicated that the decomposition steps are associated to the volatilization and/or decomposition
of the methyl esters. Kinetic data was also obtained by thermal analysis.
