摘　　要：用气相色谱法对甲基叔丁基醚(MTBE)合成后的剩余碳四馏分中含氧化合物进行了定性定量分析。采用的改性填充柱不仅使含氧化合物甲醇、MTBE与碳四烃类获得了较好的分离,而且用配外标气的方法进行了微量组分的定量分析。结果表明:该方法简便,易操作,具有较高的精密度和准确度。The oxycompound content in C4 fraction, which was a remnant in the system of methyl tert-butyl ether （MTBE）synthesized, were made quantitative and qualitative analysis by gas chromatography. Beeause the modified packed column was applied, the methanol, MTBE and C4 hydrocarbons were better separated, the trace components determined in quantitation by external standard method. The results showed that the method is simple, easy to operation with high precision and accuracy.
