Abstract

Gas chromatographic methods using solvent extraction for the analysis of cyclopropane and and trichloroethene (trichloroethylene) are described and evaluated; cyclopropane was extracted into carbon tetrachloride and trichloroethene into carbon disulphide, using chloroform and toluene respectively as the internal standards. Ostwald solubility coefficients were measured for cyclopropane, halothane and trichloroethene in Krebs solution: at 310 K the respective values +/- SEM of the Ostwald coefficients are 0.181 +/- 0.009, 0.78 +/- 0.02 and 1.54 +/- 0.02; over the temperature range 295-310 K the respective temperature coefficients of solubility are -2.27, -4.18 and -3.81 in units of per cent/K at 310 K.

摘要

本文描述并评估了使用溶剂萃取法分析环丙烷和三氯乙烯的气相色谱方法；分别以氯仿和甲苯作为内标物，将环丙烷萃取到四氯化碳中，将三氯乙烯萃取到二硫化碳中。测定了环丙烷、氟烷和三氯乙烯在克雷布斯溶液中的奥斯特瓦尔德溶解度系数：在310 K时，奥斯特瓦尔德系数的各自值±标准误差分别为0.181±0.009、0.78±0.02和1.54±0.02；在295 - 310 K的温度范围内，在310 K时溶解度的各自温度系数分别为-2.27、-4.18和-3.81，单位为%/K。
