Thermal analysis has been employed to yield information on the volatility of the biodiesel/petrodiesel since the volatility influences the ignition quality of the fuels in a compression ignition engine. The chemical composition of -10 petrodiesel (-10PD) and soybean biodiesel (SME) was analyzed by gas chromatography-mass spectrometry. The thermal volatilization of biodiesel and its blends was investigated by thermogravimetry and liquid volatile theory. Volatile index was put forward for describing biodiesel/petrodisel volatility. A good correlation model was proposed for calculate the biodiesel/petrodiesel volatility by biodiesel blending ratio. The study showed that -10PD was mainly composed of long chain alkanes: C8–C26. SME was mainly composed of long chain fatty acid methyl esters: C14:0–C24:0, C16:1–C22:1, C18:2 and C18:3. The volatile indexes of SME and -10PD were, respectively, 1.74E-04 and 3.64E-05. The biodiesel fuel was considerably more volatile in comparison to the petrodiesel fuels. The SME/-10PD volatility had relation to SEM blending ratio, it was better with increasing the SME blending ratio.
