摘要
对聚酯废料进行了碱解试验研究。给出了对苯二甲酸(PTA)收率和NaOH用量及浓度的关系;找到了较好的回收乙二醇(EG)的新方法,给出了EG收率和浓缩程度及乙醇加入量的关系。
Alkaline hydrolysis of spent materials from polyester prodction was studied, the relations between the recovery of PTA and the consumption and the concentration of NaOH were provided. A new method for recovering EG was found and the relations between EG's yield and the amount of ethanol added as well as the concentration of aqueous liquid was provided.
