摘要
描述了一种测量碳氢化合物在气相和液态水相间平衡分布的仪器。该方法采用多重平衡程序，只需对气相进行分析。由于气液相色谱法具有高灵敏度和高选择性，因此被用于碳氢化合物分析。观察到的分布情况辅以蒸汽压数据，可用于计算碳氢化合物在液相中的溶解度。在 5 至 20 °C 的温度范围内，对蒸馏水中的苯、甲苯和乙苯进行了计算；在 0 至 20 °C 的温度范围内，对人工海水中的苯、甲苯和乙苯进行了计算。详细讨论了影响结果准确性的各种因素。
A Method of Measuring the Solubilities of Hydrocarbons in Aqueous Solutions.
An apparatus is described which measures the equilibrium distribution of a hydrocarbon between a gas phase and a liquid water phase. The method involves a multiple equilibration procedure which requires the analysis of only the gas phase. Gas-liquid chromatography was used for the hydrocarbon analysis because of its high sensitivity and selectivity. Supplemented by vapor pressure data, the observed distribution can be used to calculate the solubility of the hydrocarbon in the liquid phase. This was done for benzene, toluene, and ethylbenzene in distilled water over the temperature range 5 to 20 °C and in an artificial seawater over the temperature range 0 to 20 °C. The various factors affecting the accuracy of the results are discussed in detail.
