Evaluator:
G.T. Hefter, School of Mathematical and Physical Sciences, Murdoch University, Perth, W.A., Australia. July 1985.
Critical Evaluation:
Quantitative data for the solubility of water (2) in 1-heptene (1) have been reported in the publications listed in Table 1.
The solubility of 1-heptene in dilute aqueous HNO
3
solutions have also been reported (ref 3). However, as no other data are available for comparison these values will not be considered in this Evaluation. The interested user is referred to the relevant Data Sheet immediately following this Critical Evaluation.
The reported values (ref 1 and 2) for the solubility of water in 1-heptene are listed in Table 2.
The data are in very poor agreement. In the absence of confirmatory studies selection of best values is difficult. However, it may be noted that in well characterized systems (e.g., water in benzene) the results of Englin
et al.
at
T
<300K are generally reliable whilst those of Black
et al
generally differ markedly from Recommended values. Thus values of Englin
et al.
(ref 2) have been selected as the “Best” values available although, in the absence of confirmatory studies, it is not possible at this stage to reject outright the data of Black
et al.
(ref 1).
