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

Although all the data of Rex,

of Fühner,

of Gross and Saylor,

and of Schwarz

are in good agreement, the solubility data of Rex are believed to be more reliable than the other data because Rex made measurements at more than one temperature.
All the available data for the solubility of 1-iodopropane (1) in water (2) were combined and correlated to obtain the following mass percent (1) equation:
Solubility [100 w1] = 3.4659 - 0.023046 (T/K) + 3.94424x10
-5
(T/K)
2
which yielded a standard deviation of 8.06x10
-3
and represents the solubility behavior in the temperature range from 273 to 303 K. The temperature dependence of the solubility is illustrated in
Fig. 6
. The solubility curve derived from the above regression equation shows a solubility minimum at 292.15 K. More details on the appearance of a solubility minimum in halogenated hydrocarbon - water systems are discussed in the Preface.
The tentative solubility values for this system in weight percent and mole fraction are given in Table 19, as smoothed values at 5 K intervals.
