摘　　要：建立了气相色谱同时测定反应液中的2-甲基萘和2-甲基-1，4-萘醌的方法。该法以萘为内标物，在DB-1色谱柱上进行分离，氢火焰离子化检测器。方法的回收率98％-102％，相对标准偏差小于2％。A method for the determination of 2-methylnaphthalene and 2-methylnaphthoquinone-1,4 in reaction solution by GC was developed. Naphthalene 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% - 102%, and RSD was less than 2%.
