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℃。 Orthogonal experiments were used to explore the optimal conditions for the hydrolysis of PET under microwave conditions. The effects of the main factors on the catalytic hydrolysis of PET were studied. The results showed that the main influencing factors for the rate of PET depolymerization were temperature, followed by time, and the relatively small amount of catalyst was the amount of catalyst. Under the condition of basic zinc carbonate as catalyst, the optimum conditions for the microwave hydrolysis of PET were as follows: catalyst dosage 0.75%, the reaction time was 210 min, the reaction temperature was 200 ℃.
