摘　　要：采用ＯＶ－１弹性石英毛细管柱分析了催化裂化汽油及其醚化后汽油，可测定醚化汽油中单烃组成及含氧化合物的含量、单烯烃转化率，弥补了红外法测定醚化汽油中含氧化合物的不足，为工艺条件和催化剂的选择及改进、反应机理的研究提供了重要的基础数据。同时发现此催化裂化汽油中含微量甲基叔丁基醚，对其来源应深入探讨。The gasoline fraction from catalytic cracking lower than 75℃ and etherified gasoline were analysed with GC. Fused silica capillary columns coated with OV 1 and PEG 20M were used. The composition and content of individual hydrocarbons and oxygenates were determined. The results make up the shortcoming of the IR method and provide the important basic data for selection and improvement of etherification conditions and catalysts, also for the study on the mechanism. At the same time, trace MTBE was found in gasoline from catalytic cracking and its origin should be further studied.
