Solubility of pyrene in water
t/°C103 * g1/kg105 * g1/100 g solution (compiler)108 * Mole Fraction x1 (compiler)
250.1321.321.18
290.1621.621.44
 Method/Apparatus/Procedure:
   The dynamic coupled column liquid chromatography (DCCLC) method was based on generating saturated solutions by pumping water through a column packed with glass beads that have been coated with the component (1) (generator column). The concentration of (1) in the effluent of the generator column was measured by a modification of the coupled column liquid chromatographic process that has been described in ref 1.

 Source and Purity of Materials:
   (1) Commercial product; less than 3% impurities.
   (2) Distilled over KMnO4 and NaOH and passed through a column packed with XAD-2 (Rohm and Hass, Philadelphia, Pa).

 Estimated Errors:
   Solubility: ± 0.01 mg(1)/kg(2) (standard deviation)
   Temperature: ± 0.05°C
