Abstract

Investigtions have been carried out of the solubility of 1,1,1-trichloro-2,2-bis-(p-chlorophenyl)-ethane (p,p'-isomer od DDT) and of gamma-1,2,3,4,5,6-hexachlorocyclohexane (lindane) in the systems water-dimethylketone (acetone) and water-1,4-diethyldioxide (dioxane). In addition the physical properties of these saturated ternary systems were examined such as: density, viscosity, surface tension and refractive index. The more or less sudden changes of physical properties of the investigated saturated systems in the region of about 20-25 mole per cent of the organic solvent might be explained by assuming the existance of tri - or tetrahydrates of acetone and dioxane respectively. Similar changes of pQ:ysical properti.es were also observed in solutions of about 50-60 mole per cent of the organic solvent. This was explained by supposing a desintegration of the hydrate of the organic solvents.
