Variables:
Ambient temperature: One temperature: 25 °C
Prepared by:
Z. Maczynska, A. Maczynski, A. Szafranski
Method/Apparatus/Procedure:
A mixture of (1) and (2) was equilibrated at 25 ± 0.1 °C for a minimum of 12 hrs in a 200-mL Teflon-stoppered vessel (25 cm long and 3.5 cm across) with gentle shaking, allowed to settle for 6 hrs and tested for the absence of emulsion (Tyndall effect). The aqueous and organic phases were analyzed by glc (with internal standardization) on a Hewlett-Packard Model 700 instruments equipped with a 15% SE-30 on 60/80 mesh acid-washed (CH3)2Cl2Si-treated Chromosorb P column (steel capillary 10 ft x 0.125 inch). The (1) in the aqueous phase was extracted into 5 mL of the heptane and the extract analyzed by glc.
Source and Purity of Materials:
- Phillips Petroleum Co. research grade, 99+ mole%; used as received.
- doubly distilled.
Estimated Errors:
Ambient temperature: ±0.1 K
Mass concentration (m/v) (1): 30 mg(1) dm-3 (two standard deviations)
Experimental Values:
Note: The solubility of 1-hexene in water at 25°C was reported to be 55.4 mg(1) dm-3 sln.The corresponding mass percent and mole fraction, x1, calculated by the compilers are 0.00554 g(1)/100 g sln and 1.18 × 10 -5. The compiler's calculation assumes a solution density of 1.00 g mL-1.
