The experimental condition filtration of hemimelitene content in heavy aromatics with HPLC

摘要

HPLC was applied to measure the content of hemimelitene in industry product C_9 heavy aromatics. The optimal experiment condition was filtered mainly to find out the wave-length, mobile phase, the velocity and proportion of mobile phase, chromatographic column temperature which suited for hemimelitene, to improve the chromatographic separation degree of hemimelitene. From the experiment, we can make the conclusions: when wave-length is 297nm, mobile phase are methanol and water, which mobile velocity is 0.6ml/min and proportion is 50%:50%, column temperature is 25°C, the resolution and the spectrum are the best.
