Evaluator:
A. L. Horvath, Imperial Chemical Industries Limited, Runcorn, U.K., July 1993.
Critical Evaluation:
The 1-chloropentane (1) and water (2) binary system is treated in two parts; part 1 is 1-chloropentane (1) in water (2) and part 2 is water (2) in 1-chloropentane (1).
Part 1.
The solubility of 1-chloropentane (1) in water (2) has been studied by four work groups; whereas, the solubility of water (2) in 1-chloropentane (1) has been reported in only one paper. The reported value of Booth and Everson
1
is significantly higher then other measurements and is therefore rejected. The remaining data of Wright and Schaffer,
2
of Sato and Nakijima,
3
and of Leighton and Calo
4
were combined and correlated to obtain the following mass percent (1) equation:
Solubility [100 w
1
] = 0.55726 - 3.7269x10
-3
(T/K) + 6.457x10
-6
(T/K)
2
This equation, which represents the combined data values, yielded a standard deviation of 5.27x10
-4
and represents the solubility behavior in the temperature range from 276 to 310 K. The temperature dependence of the solubility is illustrated in
Figure 10
. The solubility curve derived from the above regression equation shows a distinct solubility minimum at 288.6 K as seen in
Figure 10
. More details on the appearance of a solubility minimum in halogenated hydrocarbon - water systems are discussed in the Preface.
The tentative solubility values at 5 K intervals for 1-chloropentane (1) in water (2) in weight percent and mole fraction are presented in Table 30.
Part 2.
The solubility of water (2) in 1-chloropentane (1) has been reported only by Hutchison and Lyon
5
; therefore, no critical evaluation can be made. The interested user is referred to the appropriate compilation sheet for the solubility value at 298.15 K. The measurement is classified as tentative since no other data are available.
