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.
7,12-Dimethylbenz[a]anthracene with Water
Components:
(1) 7,12-Dimethylbenz[a]anthracene,
$\ce{ C20H16 }$;
[57-97-6]
NIST WebBook
(2) Water,
$\ce{ H2O }$;
[7732-18-5]
NIST WebBook
Experimental Values:
The solubility of 7,12-dimethylbenz[a]anthracene in water at 25°C was reported to be 0.061 mg(1) dm-3 sln and x1 = 4.26 × 10-9.
The corresponding mass percent calculated by the compiler is 6.1 × 10-6 g(1)/100 g sln.
