本文用比浊法研究了乙酸乙酯在碱性卤化物和碘化季铵水溶液中的溶解度，电解质浓度为0.025 ~ 0.400 M，温度为20 ~ 40 ℃。并将实验活度系数与基于库仑相互作用假设的各种方程计算的活度系数进行了比较。虽然相当好的半定量协议被发现在碱金属氯化物和溴化物的溶液中的乙酸乙酯，在碱金属氟化物溶液中的乙酸乙酯的实验活度系数略高于理论上发现的。理论活度系数均高于，甚至不同的符号从实验中发现的乙酸乙酯在碱和碘化季铵溶液中的系数。定性地讨论了色散力的附加影响。将由McDevit-Long理论计算的溶解度参数k n与实验测得的k n进行了比较。讨论了溶剂离散结构在盐效应理论中的重要性。
The solubility of ethyl acetate in a number of aqueous alkali halide and quaternary ammonium iodide solutions has been investigated by means of the turbidimetric method at electrolyte concentrations from 0.025 to 0.400 M and in the temperature range from 20 to 40. Theexperimental activity coefficients have been compared with those calculated from various equations based on the assumption of coulombic interactions. While fairly good semiquantitative agreement is found for ethyl acetate in solutions of alkali chlorides and bromides, the experimental activity coefficients for ethyl acetate in alkali fluoride solutions are somewhat higher than those found theoretically. The theoretical activity coefficients are uniformly higher than and even differ in sign from the coefficients found experimentally for ethyl acetate in alkali and quaternary ammonium iodide solutions. The additional influence of dispersionforces is discussed qualitatively. Solu-bility parameters, k „calculated from the McDevit-Long theory are compared with the k, found experimentally. The importance in salt effect theory of the discrete structure of the solvent is discussed.
