聚二乙烯基乙炔是乙炔法生产氯丁橡胶过程中的副产物。根据它易聚合的特点,其溶液已直接用于涂层,但是涂层因附着力差而易脱落,限制了它的应用。化学改性是改变聚合物性能的一种重要方法。以二甲苯为溶剂,ZnCl_2和FeCl_3为复合催化剂,温... 聚二乙烯基乙炔是乙炔法生产氯丁橡胶过程中的副产物。根据它易聚合的特点,其溶液已直接用于涂层,但是涂层因附着力差而易脱落,限制了它的应用。化学改性是改变聚合物性能的一种重要方法。以二甲苯为溶剂,ZnCl_2和FeCl_3为复合催化剂,温度30℃下,开展了聚二乙烯基乙炔和氯化氢反应的研究,分析了改性聚合物溶液形成的涂层的性能。实验表明,随着催化剂ZnCl_2/FeCl_3摩尔比的减小,聚二乙烯基乙炔双键转化率升高,而含氯量变化很小。根据这个结果分析,聚二乙烯基乙炔和氯化氢的反应可能包括加成、环化、和氯环化三种反应过程,它们都经历了碳正离子中间体的机理。当催化剂ZnCl_2/FeCl_3摩尔比为9:1时,此氢氯化聚二乙烯基乙炔溶液用于涂层,其涂层外观正常,附着力好,防腐性能好,拓展了其用途。 展开更多

C4 components are useful in industry and should be separated as individuals. A new process was proposed to separate them by extractive distillation, with the advantages of low equipment investment, energy consumption and liquid load in the columns. One principle to improve the extractive distillation process was put forward. Moreover, the analysis of operation state of the new process was done. There were eight operation states found for the whole process, but only one operation state was desirable. This work provides a way to effectively separate C4 mixtures and helps the reasonable utilization of C4 resource. 展开更多
