The most common catalysts for biodiesel production are homogeneous basic catalysts. In this work, through orthogonal experiments, batches of biodiesel were prepared from soybean oil by using a kind of classical cata-lyst, namely sodium hydroxide or potassium hydroxide, and the respective optimum conditions were obtained. Fourier transform infrared spectroscopy was used to compare the oil and the products in detail; gas chromatography - mass spectrometry was used to analyze biodiesel qualitatively and gas chromatography was used to analyze biodiesel quanti-tatively. Then the respective yield and the purity of the produced biodiesel under different catalytic system were com-pared. Results show that all the reactions in this work produce biodiesel with high purity, and potassium hydroxide is better than sodium hydroxide in terms of the yield and purity of the produced biodiesel.
