The solubility of 2-chloropropane (1) in water (2) has been studied by three work groups; whereas, the solubility of water (2) in 2-chloropropane (1) has not been investigated yet. The temperature dependence of the solubility between 273 and 303 K was reported in only one paper.1

Not enough workers measured the solubility of 2-chloropropane in water over common ranges of temperature to recommend solubility values. Although the data of Rex,1 of Fühner,2 and of van Arkel and Vles3 are in good agreement, the solubility data of Rex1 are believed to be more reliable than the other data because Rex made measurements at more than one temperature.

The tentative solubility of 2-chloropropane (1) in water (2) in the temperature range from 273 to 303 K in weight percent and mole fraction is listed in Table 18 at 10 K intervals. It is apparent that any solubility minimum should appear above 303 K. For further discussion on the solubility minimum in halogenated hydrocarbon - water systems; see the Preface for more details.
