SDS Volume (2272)
Volume 59. Polycyclic Aromatic Hydrocarbons: Binary Non-aqueous Systems, Part II Solutes F-Z, p 87
Original Measurements
Chang, W.; Ph.D Dissertation, North Dakota State University, ND, 1969.
Variables:
Temperature: 298 K
Prepared by:
Method/Apparatus/Procedure:
Constant temperature bath and a precision thermometer.
Mixtures of known concentrations sealed in glass ampoules 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. Solubilities at 298 K interpolated from experimental values using ln $x_{1}$ versus 1/$T$ graph.
Source and Purity of Materials:
- Purity, source and purification procedures not specified.
- 99%, Phillips Petroleum Company, Bartlesville, Oklahoma, USA, was used as received.
