中文摘要：

采用正交试验来探究碳酸盐在微波条件下水解PET的最优实验条件,并研究了主要影响因素对催化PET微波水解反应的作用规律。结果表明,影响PET解聚率的主要影响因素是温度,其次是时间,而相对影响较小的是催化剂用量;在以碱式碳酸锌为催化剂下,PET微波水解反应的最佳条件：催化剂用量为0.75%、反应时间为210 min、反应温度为200℃。

英文摘要：

The experimental conditions for hydrolysis of polyethylene terephthalate（PET）catalyzed by carbonates was optimized by the orthogonal test. The main influence factors of PET microwave hydrolysis reaction were confirmed as the reaction temperature, time, and catalyst dosage. And their effect on catalytic microwave hydrolysis of PET was studied. The results show that the sequence of influence factors is as follows： reaction temperaturereaction time catalyst dosage. The optimal experimental conditions under the catalyst of basic zinc carbonate are as follows： the catalyst dosage 0.75%, the reaction time 210 min, the reaction temperature 200℃.
