Critical Evaluation:

   Quantitative data for the solubility of 1,4-cyclohexadiene (1) in water (2) have been reported in the publications listed in Table 1.

The original data in these publications are compiled in the Data Sheets immediately following this Critical Evaluation. No data appear to have been reported for the solubility of water in 1,4 cyclohexadiene.

The solubility values of (1) in (2) are listed in Table 2. The data are in poor agreement, with those of Pierotti and Liabastre (ref 2) being approximately 20% (relative) higher than those of McAuliffe (ref 1). This situation is typical for a large number of hydrocarbon-water systems investigated by these authors and is discussed in greater detail in the Critical Evaluation of the cylclopentane-water system. In general the values of McAuliffe are much closer to accepted values (in well-characterized systems) than those of Pierotti and Liabastre. However, in the absence of confirmatory studies, the data of Pierotti and Liabastre are not rejected although they should probably be regarded only as order-of-magnitude values. The datum of McAulliffe may be considered as “Tentative”.
