The Solubility of Several Aromatic Hydrocarbons in Water,
Abstract
In order to solve a number of theoretical problems in petroleum geology, for example, the formation and disintegration of agglomerates, as well as certain practical problems in the area of petroleum refining, water pollution, etc., information is needed regarding the solubility of hydrocarbons in various types of natural solutions under various conditions. Existing literature data on the solubility of hydrocarbons, even in pure water, are quite meager. There is especially little material on the solubility of hydrocarbons in water at the high temperatures which can occur at great depths. In the study reported here benzene, toluene, o-xylene, m-xylene, n-xylene and mesitylene were used; the criterion of purity was the index of refraction. Especially pure water was obtained by passing a double distillate through a filter with a 'mixed' layer consisting of ion-exchange resins EDE-10P and KU-2. The solubilities of the aromatic hydrocarbons in water was determined in sealed ampules by the polythermic method. As is evident from graphs, the solubility curves have an extremely similar character, with the exception of benzene whose curve shape is slightly different from the other hydrocarbons. The solubility of hydrocarbons increases intensely with temperature and decreases as the number of methyl groups in the molecule is increased. As the critical point is approached the curves of different hydrocarbons show a tendency to converge, as with increase of temperature the solubility depends all the more on the structural properties of the water. Also the role of the structure of hydrocarbon molecules, including the number and location of methyl groups, is increasingly weaker.
