Critical Evaluation:

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

As only one study of the solubility of (2) in (1) has been reported (ref 2), no Critical Evaluation of those data can be made. The interested user is referred to the relevant data sheet for experimental values.

The reported values of the solubility of (1) in (2) are listed in Table 2 and plotted in Figure 1 . The agreement at 298 K between the value of McAuliffe (ref 1) and the interpolated value of Pavlova et al. (ref 2) is reasonable so the “Best” values in Table 2 may be considered “Tentative”, subject to further studies.
