摘要
建立了同时测定苯乙烯催化氧化反应液中的苯乙烯、环氧苯乙烷和苯甲醛的气相色谱分析方法。该法以正庚烷为内标物,在DB-1毛细管色谱柱上进行分离,氢火焰离子化检测器。方法的回收率98%~101.5%,相对标准偏差小于2.0%。
A method for the determination of styrene,styrene oxide and benzaldehyde in reaction solution of styrene catalytic oxidation by GC was developed.N-heptane was used as an internal standard.The samples were well separated on a DB-1 capillary column and detected with FID as a detector.The recoveries of the method were 98%～101.5%,and RSD was less than 2.0%.
