Glass Ball as Bullet Solubility System: Bicyclo[4.4.0]decane (decahydronaphthalene; decalin) with Water
Components:
   (1) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail
   (2) Bicyclo[4.4.0]decane (decahydronaphthalene; decalin); C10H18; [91-17-8]  NIST Chemistry WebBook for detail
Evaluator:
   G.T. Hefter, School of Mathematical and Physical Sciences, Murdoch University, Perth, W.A., Australia. April 1986.

 Critical Evaluation:
   Quantitative solubility data for the decalin (1) _ water (2) system 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. SOLUBILITY OF DECALIN (1) IN WATER (2)

The solubility of decalin in water has been reported only at 298K (Table 1). However, the datum of Booth and Everson (ref 1) in v/v fraction, is only an order of magnitude result and must thus be excluded. Since this leaves only the single datum of 8.89 x 10-5g(1)/100g s1n (x1 =1.16x10-7) of Price (ref 3) no Critical Evaluation is possible. Nevertheless, it may be noted that the solubility values reported by Price are usually reliable although for the higher hydrocarbons his results are often about 20% (relative) lower than Recommended values.


2. SOLUBILITY OF WATER (2) IN DECALIN (1)

As only the data of Englin et al. (ref 2) over the range 293-313K are available no Critical Evaluation is possible. However, it may be noted that the data of Englin et al. are generally reliable when T < 300K but are somewhat high at higher temperatures. The interested user is referred to the relevant data sheet for the experimental values.
