利用DB-5熔融石英毛细管色谱柱将混合芳烃各组分色谱峰与TBC色谱峰完全分离，建立了气相色谱测定混合芳烃中微量对叔丁基邻苯二酚含量的方法。结果表明，TBC含量为200~1000 mg/L时，外标法测定TBC含量的线性回归系数为0.9996，最低检测限为6 mg/L。对实际混合芳烃样品中TBC含量进行测定，相对标准偏差为3.1％。

Separate the chromatographic peak of mixed aromatic components and TBC completely by using DB -5 fused silica capillary column,to work out a method about determining the content of p-tert-Butylcatechol from mix aromatic hydrocarbon by gas chromatography. The results show that under the condition of TBC content is 200~1000 mg/L,linear regression coeffficient of TBC content is 0. 9996 by external standard method,the minimum detection limit is 6 mg/L. The relative standard deviation is 3. 1% which determined by TBC.
