Original Measurements
Lissi, E. A.; Abuin, E. B.; Bol. Soc. Chil. Quim. 1981, 26, 19-34.
Variables:
Room Temp: 293 $\pu{K}$
Prepared by:
Method/Apparatus/Procedure:
Constant temperature bath, centrifuge, thermometer, and a spectrofluorimeter.
Solubility determined indirectly from measured aqueous solubility and solute partition coefficient between n-heptane and water. Solute concentration in both phases, after equilibration and centrifugation, determined from the fluorescence intensity. This indirect method computes the solubility that is expected assuming that the dilute solution behavior extrapolates up to saturation point.
Source and Purity of Materials:
- Purity not given, commercial sample of unspecified source, was used as received.
- Purity and chemical source not given, purification procedure not specified.
Estimated Errors:
Ambient temperature: T/K: ±2. c1: Unknown.
Components:
- Naphthalene, $\ce{ C10H8 }$; [91-20-3] NIST WebBook
