SDS Volume (1753)
Volume 58. Polycyclic Aromatic Hydrocarbons: Binary Non-aqueous Systems, Part I Solutes A-E, p 300
Original Measurements
Lissi, E. A.; Abuin, E. B.; Bol. Soc. Chil. Quim. 1981, 26, 19-34.
Variables:
Room Temp: 293 $\pu{K}$
Prepared by:
Method/Apparatus/Procedure:
Constant temperature bath, centrifuge, thermometer, and a spectrofluorimeter. Excess solute and solvent were placed in glass vials, pre-equilibrated for several hours at 60-80 °C, and then equilibrated at 20 °C for several additional hours. After equilibration and centrifugation, concentrations determined from the measured fluorescence emission intensity.
Source and Purity of Materials:
- Purity not given, commercial sample of unspecified source, was used as received.
- Purity and chemical source were not given, purification procedure not specified.
Estimated Errors:
Ambient temperature: T/K: ±2.
Mass concentration (m/v) (1): c1: ±Unknown.
Components:
- Coronene, $\ce{ C24H12 }$; [191-07-1] NIST WebBook
- Heptane, $\ce{ C7H16 }$; [142-82-5] NIST WebBook
