| Popis: | The solubility of sodium palmitate has been determined in eleven additional solvents over a wide range of temperature and composition, thus extending to nineteen the total number in which solubility has been investigated. There are three main problems of theoretical interest in this work: the first is the correlation of the solubility behavior of the typical soap, sodium palmitate, with the physical and chemical characteristics of the solvents, the second is the investigation of the properties and structure of the phases separating under different portions of the solubility curve, and the third is the relation of these facts to the new field of organic colloid chemistry. Such information is of interest in commercial applications in the manufacture of soap, refined vegetable oil, shaving preparations, shampoos, hair tonics, numerous medicinal preparations, specialized detergent solutions, cosmetics, fruit and vegetable sprays, toothpaste, lubricating greases, solid coal-dust fuel, and solutions for breaking emulsions, for in all these products a soap is dissolved or dispersed in one or more organic liquids. In general, the solubility of sodium palitate in the solvents employed appears to vary in about the way that would be expected from their polarity, their internal pressure, and their ability to form hydrogen bonds, just as in the case of non-colloidal, non-electrolytic solutions. |
