摘　　要：采用高效液相色谱法分析喷气燃料HDF 1中的抗氧化剂 2 ,6 二叔丁基对甲酚 (简称BHT)含量 ,研究了二元混合流动相中甲醇 乙酸缓冲液的比例对燃料主体和BHT分离效果的影响 ,选择了最佳分离条件 (甲醇所占体积分数为 85 % ,流速为 1mL/min) ,在此条件下 ,可测出质量分数为 1× 10 -5的BHT。用该喷气燃料配制了BHT质量分数在 2 0× 10 -6到 12 0× 10 -6之间的标准溶液 ,考察了BHT质量分数与峰面积之间的关系 。The content of antioxidant of 2,6 di tertbutyl 4 methylphenol(BHT) in a new aviation jet fuel (HDF 1) was determined by high performance liquid chromatography. The influences of the volume ratio of methanol and acetate buffer and the flow rate for BHT separation from HDF 1 were studied and the best analysis conditions were obtained. The optimum volume ratio is 85∶15 and the optimum flow rate is 1 mL/min. The relation of BHT mass fraction and its peak area has been analyzed and simulated. It was found that they had a good linear relationship.
