摘　　要：为了监控叔丁基对苯二酚的反应过程,提高收率和保证产品质量,探讨了用毛细管气相色谱分析产品的试验方法。测定了对苯二酚、叔丁基对苯二酚、2,5-二叔丁基对苯二酚的保留时间和相对校正因子,回收率分别为100.3%、98.2%和101.8%。tea-Butyl hydroquinone is one of the function superior food antioxidant. In order to monitor its experiment course and increase yield and insure product quality, this paper explores experiment methods of product by capillary gas chromatography analysis. Preservation time and relative rectification factor of hydroquinone,tert-butyl hydroquinone and 2,5-di-tert-butyl hydroquinone were determined. The recoveries are 100.3% ,98.2% and 101.8% respectively.
