摘要
建立了一套临界参数测定装置,该装置使用开管法,并以界面消失作为判断临界点的标准。测定了正戊烷的临界参数以证实该装置的可靠性。测定了1-戊烯、3-甲基-1-丁烯、1-己烯和乙酸异丙酯的临界参数。同时测定了以上五种物质在高温范围内的饱和蒸汽压和饱和液体密度。本文所提供的绝大多数实验数据和关联式是首次发表的。
An experimental appratus was established for determinating critical point. Open tube method and the disappearance of the meniscus as the criterious of derminating critical point were adopted. The reliability of the apparatus had been checked by measuring the critical constants of n-pentane. The critical parameters of 1-pentene, 3-methyl-1-butene, 1-hexene and isopropyl acetate were determined. The vapor pressure and saturate liquid density of the five compounds were determined in high temperature. Most of the experimental and correlated data in the article are published at first time.
