Glass Ball as Bullet Solubility System: Nitroethane with Heptane

Components:
   (1) Heptane; C7H16; [142-82-5]  NIST Chemistry WebBook for detail
   (2) Nitroethane; C2H5NO2; [79-24-3]  NIST Chemistry WebBook for detail

Original Measurements:
   Komarova, E.G.; Kogan, V.B., Zh. Prikl. Khim. (Leningrad) 37, 1776-86 (1964).

Variables:
   Temperature = 293 K

Prepared By:
   V. P. Sazonov

Experimental Remarks:

   The mole fraction of nitroethane in the (2)-rich phase at equilibrium at 293.2 K was reported to be x1 = 0.1711, corresponding 100 w1 = 11.17 (compiler).
The mole fraction of nitroethane in the (1)-rich phase at equilibrium at 293.2 K was reported to be x1 = 0.8695, corresponding 100 w1 = 80.23 (compiler).

Experimental Data:   (Notes on the Nomenclature)
   Method/Apparatus/Procedure:
   The analytical method was used. A mixture of (1) and (2) was placed in a thermostated cell and stirred for an hour. The compositions of the phases were determined by gas chromatography.

Source and Purity of Materials:
   (1) Distilled in 1.2 m packed fractionating column; b. p. = 114° C; n(20°C,D) = 1.3920; d(20 °C,4 °C) = 1.0520.
   (2) Distilled in 1.2 m packed fractionating column; b. p. = 98.4°C; n(20°C,D) = 1.3877.

Estimated Errors:

   Temperature: control to ±0.1 K
