摘    要:为了降低水洗过程中F_(22)和C_2F_4产品的损失,对这两个物质在水、HCl及NaCl水溶液中的溶解度进行了研究。利用微量气体吸收器测定了这些溶解度。实验结果表明上述电解质有明显的盐析效应。本文根据实验数据计算了F_(22)和C_2F_4的Henry常数和盐析系数。并满意地关联为温度与电解质浓度的多项式。也计算了其它的一些热力学常数。还应用气体溶解度的分子热力学模型通过拟合实验数据得到这些气体的分子参数。

关 键 词:氟里昂  四氟乙烯  溶解度  盐效应  吸收器  电解液

Abstract:Attempting to reduce the loss of the products F_(22) and C_2F_4 during washing processing, the solubilities of the two given compounds in water, aqueous HCl and the solution of NaCl have been studied respectively. The solubilities were determined with the use of a micro gas absorbing apparatus. Experimental results show that the "salting out" effect produced by the presence of these electrolytes. Working with the experimental data, further, it is possible to calculate the Henry's constants of F_(22) and C_2F_4 in the electrolytic solutions and the salting out coefficients and to get the satisfactory correlations from these data in polynomial forms with respect to temperature and the electrolytic concentrations. Various other thermodynamic constants were also obtained. By a molecular thermodynamic model for gas solubility, the molecular parameters for these gases have been estimated by proper fitting of the experimental data.
Keywords:freon  tetrafluoro ethylene  solubility  salt effect  absorber  electrolytes
