Solubility System: 1,4-Pentadiene with Water (Original Report)

Components:
(1) 1,4-Pentadiene, C5H8; [591-93-5] NIST Chemistry WebBook
(2) Water, H2O; [7732-18-5] NIST Chemistry WebBook
Variables:
Temperature: One temperature: 25°C
Experimental Remarks:
The solubility of 1,4-pentadiene in water at 25°C was reported to be 558 g(1)/106 g(2).
The corresponding mass percent and mole fraction, x1, calculated by the compilers are 0.0558 g(1)/100 g sln and 1.48 × 10-4.
Method/Apparatus/Procedure:

In a 250-mL bottle, 10-20 mL of (1) was vigorously shaken for 1 hr, or magnetically stirred for 1 day, with 200 mL of (2) at 25 °C. The bottle was set aside for 2 days to allow droplets of undissolved (1) to separate. Absence of emulsion was checked microscopically. A sample of the hydrocarbon-saturated water was withdrawn with a Hamilton syringe and gas liquid chromato-graphed in conjunction with a flame-ionization detector.

Source and Purity of Materials:

(1) Phillips Petroleum or Columbia Chemical; used as received.
(2) Distilled.

Estimated Errors

Temperature: ±1.5 K
Solubility: 27 g(1)/106 g(2) (standard deviation of mean)
