Volume 59. Polycyclic Aromatic Hydrocarbons: Binary Non-aqueous Systems, Part II Solutes F-Z, p None

Original Measurements

Heric, E. L.; Posey, C. D.; J. Chem. Eng. Data 1964, 9, 35-43.

Variables:

Room Temp: 298 $\pu{K}$

Prepared by:

W.E. Acree, Jr.

Method/Apparatus/Procedure:

Constant temperature bath, thermometer, and a precision refractometer.
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:

1. Eastman Chemical Company, Rochester, New York, USA, was used as received.
2. ACS Grade, Matheson, Coleman and Bell, USA, was dried over calcium hydride and distilled to a final purity of 99.8%.

Estimated Errors:

Ambient temperature: T/K: ±0.01. x₁: precision ±0.0005.
