| 摘 要： | 随着我国加入世贸组织，乙二醇产品面临国际竞争，这种竞争对乙二醇产品质量提出了更高要求。不仅表现在为了降低成本扩大生产规模和使用高性能的银催化剂，影响乙二醇产品质量的因素很多：如环氧乙烷原料的性质、循环水水质、装置中产生的铁锈、再沸器等。提高产品质量的措施为：一方面实行乙烯环氧化反应的最佳操作，减少装置运行中的铁锈，改进催化剂的装配。提高催化剂的选择性；另一方面改进反应器，优化吸收塔的条件，采用紫外光辐照法提高乙二醇产品的UV值。该文综述了影响乙二醇产品质量的因素以及在提高产品质量方面的研究进展。

| Abstract: | As China joined the WTO,the ethylene glycol is facing the international competition.In order to strongly improve the quality of EG,the manufacture scale should be enlarged and high performance Ag catalyst should be used.There are many factors affected the quality of ethylene glycol:for example,the chemical property of ethylene oxide,quality of recycling-water,rust from EO/EG equipment and re-boiler etc.The measures have been taken to improve the quality of EG,on the one hand,enforcing the optimal operation of ethylene cycle-oxidation,reducing rust from EO/EG equipment,modifying catalyst pack-mode and enhancing selectivity of Ag-catalyst;on the other hand,mending reactor,optimizing condition of absorption tower and adopting UV irradiation to increase UV-absorbance of ethylene glycol.In this paper the study of developing and improving EG quality was discussed. |
