摘要
采用了开管法装置,以界面消失法作为判断临界点的标准,测定了1-己烯、环戊烯、1-氯丙烷、2-氯丙烷、乙酸异丁酯、环己烯的全部临界常数。同时还测定了上述物质直至接近临界点的蒸气压及饱和液体密度,并提供了与温度关联式的系数值。绝大部分的测定和关联值是首次提出的。
Opon-ended tube method and the disappearance of the meniscus as the criterion of critical point were adopted to determine the critical constants for 1-hexene, cyclopenten, 1-chloropropane, 2-chloropropane, isobutyl acetate, cyclohexene. Vapor pressures and saturated liquid densities for all above compounds were also determined near the critical points, and the coefficients of correlation to temperature are provided. Most of the experimental data were presented for first time.
