裂解汽油中C_4和C_5异构烯烃的分析

介绍了一种适于沸点范围从初馏点到２１０℃的裂解汽油中Ｃ４和Ｃ５异构烯烃的分析方法——以两根单柱分析系统的数据为基础，经关联计算进行定量。它具有操作简便、移植便利、分析结果重复性好、提供的信息全面等特点，满足了实际应用分析的要求。

The Analysis of C 4 and C 5 Olefins in Cracking Gasoline

The paper described the analytical method of butenes and pentenes in cracking gasoline with a boiling point range from initial to 210 degrees C. Beside the C3 (propane + protene) and n, i-C4 = (n-butene + i-butene) combine peaks, all C2-C5 components in the sample were separated on the OV-1 column. The proportion of the combined peaks was determined on the Al2O3 column. The quantitative results were calculated on the data determined from the above one-column analytical systems with a relative standard deviation < 8%. Comparing with the ASTM D2427-87, the simple operation, easy application, good repetition and all component results were characteristic of the method.
