Determination of 2,6-Di-Tertbutyl-4-Methylphenol in an Aviation Jet Fuel by High Performance Liquid Chromatography
喷气燃料中抗氧剂2,6-二叔丁基对甲酚的高效液相分析

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.
