摘 要: | 采用滴定量热法研究P204钠(钾、铵)-仲辛醇-煤油等体系在滴加水过程中的热量变化, 得到两种不同类型的量热曲线, 在此基础上解释了微乳状液的形成过程和水以两种状态─缔合水和自由水存在, 还以简化的模型定性地讨论了滴水过程中微乳状液颗粒大小的变化。

Investigation of extraction process by titration calorimetry II. Study on formation process of microemulsion by thermogram of titration of water |

Abstract: | Using the extractants such as naphthenic acid-sec-octyl alcohole and P204-sec-octyl alcohol- proved the formation of a W/O microemulsion in the saponified extractant. In this paper, the authors studied the above-mentioned systems by titration calorimetry. From titration thermogram, the existence of two states of water, bound water and free water, were demonstrated. According to a sketch of the suggested structure of the microemulsion, the size parameters of the microemulsion have been evaluated. |
