Method/Apparatus/Procedure:
A saturated solution of (1) in (2) was vigorously stirred in a 250 mL flask for 24 hrs. and subsequently settled at 25 °C for at least 48 hrs. Then the saturated solution was decanted and filtered and 50-100 mL extracted with approximately 5 mL of cyclohexane in a separatory funnel. After shaking for 2 hrs. the cyclohexane extract was removed for analysis. An Aminco-Browman spectrophotofluorometer (American Instruments Ltd.) was used for analysis. Many details are given in the paper.
Source and Purity of Materials:
- Aldrich Chemicals, Eastman Kodak, or K and K Laboratories, commercial highest grade; used as received.
- Doubly distilled
Estimated Errors:
Mass concentration (m/v) (1): ±2 × 10-5 mg(1) dm-3 sln (maximum deviation from several determinations).
Components:
- Coronene, $\ce{ C24H12 }$; [191-07-1] NIST WebBook
- Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook
Experimental Data
The solubility of coronene in water at 25°C was reported to be 0.00014 mg(1) dm-3 sln and x1 = 8.56 × 10-12.
The corresponding mass percent calculated by the compiler is 1.4 × 10-8 g(1)/100 g sln.
