摘要
聚对苯二甲酸乙二醇酯(PET)属于合成材料,由对苯二甲酸和乙二醇经酯化和缩聚反应等手段制成。因为社会上对这一物质需求的不断增多,PET生产大量增加,但PET产品很容易形成"白色污染",所以进行回收和环保是极其必要的。从聚对苯二甲酸乙二醇酯的再生利用现状以及展望等多方面进行介绍与讨论。
In chemistry, polyethylene terephthalate (PET) is a synthetic material, which is made from terephthalic acid and ethylene glycol through esterification and polycondensation.Because of the increasing demand for this material in the society, the production of PET polyester has increased a lot, but PET products are easy to form "white pollution" .Therefore, recycling and environmental protection are extremely necessary.In this paper, we will introduce and discuss the status and Prospect of the regeneration and utilization of ethylene glycol terephthalate.
