Compilation - Naphthalene with n-Hexadecane (IUPAC SDS Volume 59)
SDS Volume (1841)
Volume 59. Polycyclic Aromatic Hydrocarbons: Binary Non-aqueous Systems, Part II Solutes F-Z, p 88
Original Measurements
Heric, E. L.; Posey, C. D.; J. Chem. Eng. Data 1964, 9, 35-43.
Variables:
Room Temp: 298 $\pu{K}$
Prepared by:
Method/Apparatus/Procedure:
Constant temperature bath, thermometer, and a precision refratometer.
Excess solute and solvent placed in glass bottles and allowed to equilibrate with gentle agitation for several days at constant temperature. Refractive indices of saturated solutions were measured and solubilities obtained using a calibration curve. Attainment of equilibrium verified by making repetitive measurements after several additional days.
Source and Purity of Materials:
- Eastman Chemical Company, Rochester, New York, USA, was used as received.
- Practical Grade, Eastman Chemical Company, was dried over phosphorous pentoxide and distilled to a final purity of 99.1%.
Estimated Errors:
Ambient temperature: T/K: precision ±0.01. x1: precision ±0.0005.
Components:
- Naphthalene, $\ce{ C10H8 }$; [91-20-3] NIST WebBook
- Hexadecane, $\ce{ C16H34 }$; [544-76-3] NIST WebBook
