Glass Ball as Bullet Solubility System: 1-Pentyne with Water

   (1) Water; H2O; [7732-18-5]  NIST Chemistry WebBook for detail
   (2) 1-Pentyne; C5H8; [627-19-0]  NIST Chemistry WebBook for detail

Original Measurements:
   McAuliffe, C., J. Phys. Chem. 1966, 70, 1267-75.

   Temperature = One temperature: 25 °C

Prepared By:
   A. Maczynski, Z. Maczynska, and A. Szafranski

Experimental Remarks:

   The solubility of 1-pentyne in water at 25 °C was reported to be 1570 g(1)/106 g(2).
The corresponding mass percent and mole fraction, x1, calculated by the compilers are 0.1570 g(1)/100 g sln and 4.15 x 10-4.

Experimental Data:   (Notes on the Nomenclature)
   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 A sample of the hydrocarbon-saturated water was withdrawn with a Hamilton syringe and gas liquid chromato-graphed in conjunction with a flame-ionization detector.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:
   Solubility: 33 g(1)/106 g(2) (standard deviation of mean)
   Temperature: ± 1.5 K
