Critical Evaluation:

   Quantitative solubility data for the system 1,3,5-cycloheptatriene (1) and water (2) have been reported in the publications listed in Table 1.

The original data in these publications are compiled in Data Sheets immediately following this Critical Evaluation. For convenience, further discussion of this system will be in two parts.

Solubility values of (1) in (2) are listed in Table 2 and plotted in Figure 1. The data at 298 K are in reasonable agreement. However, it should be noted that the results of Pierotti and Liabastre (ref 2) are generally higher than “Recommended” values in well characterized systems (e.g. benzene in water). Their results at temperatures other than 298 K should be regarded with some caution.

The solubility of water in 1,3,5-cycloheptatriene has been reported only by Englin et al. (ref 1) and so no Critical Evaluation can be made. The interested user is referred to the appropriate Data Sheet for solubility values. However it should be noted that the data of Englin et al. are generally reliable at lower temperatures but are high when T > 300 K.
