摘要
介绍了国内外开发的聚对苯二甲酸乙二醇(酯PET化)学解聚的工艺方法,包括水解法、甲醇解聚法、乙醇解聚法、乙二醇解聚法等,对主要的化学解聚方法的优缺点进行了综合比较,指出我国应该加强PET解聚技术的研究以,彻底解决资源紧张和白色污染问题。
Several methods of chemical depolymerization of PET at home and abroad were introduced, including hydrolysis method, methanol depolymerization method, ethanol depolymerization method, and ethylene glycol depolymerization method etc. The advantages and disadvantages of main chemical depolymerization methods were compared comprehensively. Some suggestion was given, the research on PET polyester depolymerization should be strengthened to thoroughly solve the problem of resource tension and white pollution.
