The prepared catalysts were used in the esterification reaction of oleic acid. The structural and morphological characteristics of the powders were analyzed by X-ray diffraction, scanning electron microscopy, energy dispersive X-ray spectrometry, and Fourier transform infrared spectroscopy. The application of catalysts resulted in a yield of 41.6% of methyl oleate.309-315porEsterificationMicrowave-Assisted hydrothermal methodNanoparticlesTin oxideArtigo10.1590/0366-69132016623632048S0366-69132016000300309Acesso aberto2-s2.0-84990990200S0366-69132016000300309.pdf
