摘　　要：紫外透光率是乙二醇产品质量的重要指标。通过实验研究,首次确认了影响煤制乙二醇紫外透光率几种杂质的影响程度为:草酸二乙酯>1,2-己二醇>乙二醇甲醚>碳酸乙烯酯>二乙二醇乙醚;自然光照能够一定程度提高煤制乙二醇的紫外透光率;活性炭对煤制乙二醇中的几种杂质均有吸附作用,可以提高其紫外透光率。实验研究结果对煤制乙二醇产品质量的提高具有指导意义。UV transmittance is an important quality indicator of glycol product. For the first time, experi- mental research have confirmed some impurities that influence UV transmittance of SEG, and the degree of the influence as follows ： diethyl oxalate 〉 1, 2 - hexanediol 〉 2 - methoxyethanol 〉 ethylene car- bonate 〉 diethylene glycol monoethyl ; Natural light can improve the UV transmittance of SEG to a certain extent; activated carbon can adsorb impurities in the experiment, and can be used to improve the UV transmittance of SEG. The results of experiments have guiding significance to improve the UV transmit- tance of SEG.
