Quantitative solubility data for the system methylcyclopentane (1) - water (2) have been reported in the publications listed in Table 1.

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



1. THE SOLUBILITY OF METHYCYCLOPENTANE (1) IN WATER (2)

The solubility data for methylcyclopentane in water at 298K are listed in Table 2. The datum of Krzyzanowska and Szeliga (ref 5) has been excluded from consideration as it does not appear to be independent of that of Price (ref 4). The high temperature data of Guseva and Parnov (ref 1) presumably made in sealed tubes are rejected because of inadequate specification of system conditions (especially pressure). All other data are given in Table 2.



2. THE SOLUBILITY OF WATER (2) IN METHYLCYCLOPENTANE (1)

The solubility of water in methylcyclopentane has been reported in only one publication: Englin et al. (ref 2), and thus no Critical Evaluation can be given. However, it should be noted that in well characterized systems (e.g. benzene-water), the data of Englin et al. are generally reliable at lower temperatures but are higher than 'Recommended' values when T > 300K. The interested user is referred to the appropriate data sheet for the original values.
