Abstract (english)

Determined were the consta nts of solubility isotherms for the
solutions of the following organic compounds in a mixture of methanol
and water: benzen e (20° C), bromobenzene (0°), hexane (0°), tetrachloromethane (0°), toluene (0°), ethylbromide (0°), chloroform (0°) and heptane (0°). The authors show that the solubility of thenvestigated organic compounds at the intersections of the isotherms changes according to the same law for the systems methanol-water and
the systems ethanol-water. Lower concentrations of water diminish
the solubility of the organic compounds in the mixture alcohol-water
relatively more tha n higher concentrations. The inner angles under
which two isotherms intersect vary in the systems organic compound
- water - methanol between 165 and 175° and in the systems
with ethanol between 169 and 175° in the majority of the systems
investigated.
