Evaluator:
G.T. Hefter, School of Mathematical and Physical Sciences, Murdoch University, Perth, W.A., Australia.
A. Maczynski, Institute of Physical Chemistry, Polish Academy of Sciences, Warszawa, Poland. April 1986.
Critical Evaluation:
Quantitative solubility data for 1–ethylnaphthalene (1) in water (2) have been reported in the publications listed in Table 1. No data have been reported on the solubility of water in 1-ethylnaphthalene.
The original data in all of these publications are compiled in the Data Sheets immediately following this Critical Evaluation.
The data available (Table 1) are summarized in Table 2 and plotted in
Figure 1
. For the purpose of this Evaluation the values of Schwarz (ref 3) are not considered as independent determinations. Nevertheless, the excellent agreement between the data of Schwarz and Wasik (ref 2,3) and Mackay and Shiu (ref 1) art 298K suggests the values of Schwarz and Wasik at other temperatures can be considered as Tentative.
