Glass Ball as Bullet Solubility System: Ethene with Benzene

Components:
   (1) Ethene; C2H4; [74-85-1]  NIST Chemistry WebBook for detail
   (2) Benzene; C6H6; [71-43-2]  NIST Chemistry WebBook for detail

Original Measurements:
   Narasimhan, S.; Nageshwar, G.W., Chem. Petro-Chem. J. (India) 1979, 10, 13-15

Variables:
   Temperature = 293.15 K
   Pressure = 101.325 kPa

Prepared By:
   W. Hayduk

Experimental Remarks:

   It was confirmed by personal communication that the solubility's were measured at atmospheric pressure.

Notes:
   1  Although not specifically stated in the paper, it is assumed that the mole fraction solubility is for a total pressure of 101.325 kPa.
   2  Calculated by compiler; a gas molar volume of 23910 cm3/mole was used at 293.15 K and 101.325 kPa for the calculation of L, and Henry's law was assumed to apply for the calculation of x1.

Method/Apparatus/Procedure:
   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. Benzene was distilled twice in a laboratory packed column.

Estimated Errors:
   Solubility: δx1/x1 = ± 3% (Estimated by compiler)
