| Abstract: | In this paper,methyl palmitate,methyl oleate and methyl linoleate in the bio-diesel,which was prepared from abandoned corn oil with ionic liquids,were detected by gas chromatography.PEG-20 M packed column and hydrogen flame detector were used for optimizing the condition of chromatograph.The best conditions for the determination were established as follows: the temperature of column was 170 ℃,the vaporizer temperature was 230 ℃,the detector temperature was 250 ℃,the pressure of flow rate of carrier gas,air and hydrogen were 35 mL/min,450 mL/min and 50 mL/min,respectively.The three components were separated within 55 min. |
