Glass Ball as Bullet Solubility System: Ethene with 1-Propanol

   (1) Ethene; C2H4; [74-85-1]  NIST Chemistry WebBook for detail
   (2) 1-Propanol; C3H8O; [71-23-8]  NIST Chemistry WebBook for detail

Original Measurements:
   Narasimhan, S.; Natarajan, G.S.; Nageshwar, G.D., Indian J. Technol. 1981, 19, 298-299.

   Temperature = 293.15 K, 298.15 K
   Pressure = 293.15 K, 298.15 K

Prepared By:
   W. Hayduk

Experimental Remarks:

   Gas molar volumes of 23910, and 24330 cm3/mole were used for the temperatures 293.15 K, and 298.15 K, respectively, and for a pressure of 101.325 kPa when calculating L.
It was confirmed by private communication with Dr. Nageshwar that x was for a total pressure of one atmosphere.

   1  Calculated by compiler. It is assumed that the mole fraction solubility, x, as originally given, is for a total pressure of 101.325 kPa although not specifically so stated in the paper. The mole fraction solubility is calculated for a partial pressure of 101.325 kPa.

   The solvent was held in a jacketed burette. Constant temperature water was circulated through the jacket. Gas was bubbled through the solvent until saturated. The dissolved gas content was determined by an electrometric dead-stop titration technique which yielded the bromine number. The electrometric titrator was based on a design given in Ref. 1.

Source and Purity of Materials:
   1. Ethene prepared by catalytic dehydration of ethanol over activated alumina at 350-400 °C and analyzed by chromatography. Purity not given.
   2. 1-Propanol was treated for the removal of aldehydes and ketones and then distilled twice in a packed column.

Estimated Errors:
   Solubility: δ x1/x1 = ± 3% (Estimated by compiler)
