Volume 59. Polycyclic Aromatic Hydrocarbons: Binary Non-aqueous Systems, Part II Solutes F-Z, p None
Original Measurements
Sunier, A. A.; Rosenblum, C.; J. Phys. Chem. 1928, 32, 1049-1055.
Variables:
Room Temp: Temperature $\pu{K}$
Prepared by:
Method/Apparatus/Procedure:
Constant temperature bath and a precision thermometer.
Mixtures of known concentrations sealed in glass tubes and placed in constant temperature to equilibrate. Samples were rotated while bath temperature slowly increased. Solubility determined by visual noting the temperature at which the last trace of solid solute disappeared. Measurements repeated several times to verify results.
Source and Purity of Materials:
- Purity not specified, Eastman Kodak Company, Rochester, New York, USA, was recrystallized several times from methanol.
- Purity not given, Eastman Kodak Company, was distilled shortly before use.
Estimated Errors:
Ambient temperature: T/K: precision ±0.1. x1: ±0.002 (compiler).
Components:
- Naphthalene, $\ce{ C10H8 }$; [91-20-3] NIST WebBook
- 1,2-Dichloroethane, $\ce{ C2H4Cl2 }$; [107-06-2] NIST WebBook
