摘要
根据对苯二甲酸与乙二醇缩聚反应中所需高真空条件下的反应时间、产物聚对苯二甲酸乙二醇酯的内在质量以及Sb2O3催化剂的各项物理指标等三方面因素提出了综合评价Sb2O3催化活性的方法,并依据该方法对数种国产和进口的Sb2O3在对苯二甲酸与乙二醇缩聚反应中的催化活性进行了评定。试验表明,该方法能较全面地评价Sb2O3,其结果与实际生产中所反映的使用情况基本一致。
A method has been proposed for evaluating the catalytic activity of Sb 2O 3 for the condensation reaction of terephthalic acid and ethylene glycol with respect to reaction under high vacuum,quality of polyethylene glycol terephthalate and other related physical properties of the catalyst.The evaluation results are found to be basically in conformation with those of practical production.
