摘要
为解决某些物理性质相近、化学性质相似的物质难分离的问题,根据不同极性的分子在电场作用下移动的难易程度不同,首次提出了物质分离的一种新方法。论文研究了静电场对液体的作用,实验中发现了在高压电场作用下四氯化碳、乙酸乙酯、硝基苯以及苯胺等物质发生了前人未曾报道过的"回流"现象,并考察其影响因素。结果表明,高压静电场可导致某些电导率小的液体产生"回流"现象,并且该现象对某些液体混合物具有一定的分离效果。
To solve the difficult issue of separation of some substances that physical properties and chemically were similar, depending on the difficulty of the different polarity of the molecules to move under the electric field, a new method was proposed for material separation for the first time. The separation device was independently designed and processed, after considering various factors and many improvements. Besides, the influence of the electrostatic field on the liquid was studied. The separation experiment was also conducted. The phenomenon that some liquid such as carbon tetrachloride, ethyl acetate, nitrobenzene and aniline, ＂reflux＂ in the strong electric field which the predecessors had not yet reported, was discovered in the experiment. The results showed that the liquid mixture with different polarity which was studied in the experiment couldn＇t be separated significantly using the device, the ＂reflux＂ phenomenon could take place in some liquids with small electrical conductivities, which also had effect of separating some liquid mixtures.
