SDS Volume (1967)
Volume 59. Polycyclic Aromatic Hydrocarbons: Binary Non-aqueous Systems, Part II Solutes F-Z, p None
Original Measurements
Domanska, U.; Pol. J. Chem. 1981, 55, 1715-1720.
Variables:
Room Temp: Temperature $\pu{K}$
Prepared by:
Method/Apparatus/Procedure:
Constant temperature bath and a precision thermometer.
Solubilities were measured using a dynamic method. Mixtures of known concentrations were sealed in thick-walled glass ampoules and placed in a constant temperature to equilibrate. Bath temperature was slowly increased by 2 K per hour. Solubility determined by visually noting the temperature at which the last trace of solid solute disappeared.
Source and Purity of Materials:
- Purity not specified, P.O.Ch., Gliwice, Poland, was vacuum sublimed to a melting temperature of 80.25°C.
- Initial purity not specified, KochLight, was used as received.
Estimated Errors:
Ambient temperature: T/K: precision ±0.1. x1: to 3 significant figs. (compiler).
Components:
- Naphthalene, $\ce{ C10H8 }$; [91-20-3] NIST WebBook
- 1-Octanol, $\ce{ C8H18O }$; [111-87-5] NIST WebBook
