Krzyzanowska, T.; Szeliga, J.; Nafta (Katowice) 1978, 12, 413-7.

Variables:

Temperature: 25 °C

Prepared by:

M.C. Haulait-Pirson

Method/Apparatus/Procedure:

Saturated solutions of (1) in (2) were prepared in two ways. First, 200 microliters of (1) was injected into 20 mL of (2) and thermostatted at 25 °C. Second, the mixture of (1) and (2) as above was thermostatted at 70 °C and then cooled to 25 °C. The time required to obtain equilibrium was three weeks. The solubility of (1) in (2) was measured by glc. A Perkin-Elmer model F-11 gas chromatograph equipped with a 100-150 mesh Porasil column (70 °C) and a flame ionization detector was used. Saturated solutions of heptane in 92) were used as standard solutions.

2-Methylpentane with Water

Components:

(1) 2-Methylpentane, $\ce{ C6H14 }$; [107-83-5] NIST WebBook
(2) Water, $\ce{ H2O }$; [7732-18-5] NIST WebBook

Experimental Values:

The solubility of 2-methylpentane in water at 25°C was reported to be 13.00 mg(1)/kg(2).
The corresponding mass percent and mole fraction, x1, calculated by compiler are 0.0013 g(1)/100 g sln and 2.72 × 10-6.
Editor's Note: Based on the results for this and other hydrocarbon-water systems, uncertainty exists about whether the datum compiled here is independent of that of Price for the same system (see previous page).
