Original Measurements

Mel'nikova, I. K.; Zhuravlev, E. F.; Obshch. Khim. 38, 2147-50 (1968)

Variables:

Room Temp: 283 - 313 $\pu{K}$

Prepared by:

V.P. Sazonov

Method/Apparatus/Procedure:

Two methods were used. The solubility temperatures of the liquid phases were determined by the synthetic method (Alekseev [1]) The analytical method described in Nikurashina and Mertslin [2] was used for determining equilibrium liquid phase compositions. Samples from coexisting liquid phases at equilibrium were analyzed by refractometry. No experimental details given.

Source and Purity of Materials:
  1. Source not specified; freshly distilled.
  2. Source not specified; freshly distilled.
  3. Source not specified; freshly distilled.
Estimated Errors:

Ambient temperature: Not specified.

Components:
  1. Nitromethane, $\ce{ CH3NO2 }$; [75-52-5] NIST WebBook
  2. 1,2,3-Propanetriol, $\ce{ C3H8O3 }$; [56-81-5] NIST WebBook

Experimental Data

The solubility temperatures of liquid phases were determined in ternary mixtures with a constant mass relationship of (1) and (3), respectively, 10.0:90.0, 20.0:80.0, 30.0:70.0, 40.0:60.0, 50.0:50.0, 60.0:40.0, 70.0:30.0, 80.0:20.0, and 90.0, 10.0. These data are also presented in graphical form as isothermal curves of ternary system solubility.
The compositions of two coexistent liquid phases at 20°C are also presented in graphical form.
