| 摘 要： | 采用高效液相法分析喷气燃料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 ,结果表明线性关系良好。

| Abstract: | 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. |
