Variables:
Room Temp: 291 - 455 $\pu{K}$
Prepared by:
N.I. Lisov, N.V. Sazonov, V.P. Sazonov
Method/Apparatus/Procedure:
Two methods were used. The solubility temperatures are determined by the synthetic method. The analytical method was used for determining of equilibrium liquid phase composition. Samples from coexisting liquid phases at equilibrium were analyzed by refractometry. No experimental details given.
Source and Purity of Materials:
- Source not specified; pure grade reagent; dried over $\ce{CaCl2}$ and distilled.
- Source not specified; pure grade reagent.
- Source not specified; pure grade reagent.
Estimated Errors:
Ambient temperature: Not specified.
Mass concentration (m/v) (1): Not specified.
Components:
- Nitroethane, $\ce{ C2H5NO2 }$; [79-24-3] NIST WebBook
- 1,2,3-Propanetriol, $\ce{ C3H8O3 }$; [56-81-5] NIST WebBook
- 1-Dodecanol, $\ce{ C12H26O }$; [112-53-8] NIST WebBook
Experimental Data
The solubility temperatures of liquid phases were determined in ternary mixtures with a constant mass content of (2), respectively 20.0, 50.0 and 70.0 mass % and in ternary mixtures with constant mass relationship of (1) and (3) as 10.0:90.0, 20.0:80.0, 30.0:70.0, 50.0:50.0, 80.0:20.0 and 90.0:10.0 respectively (see Tables 1 and 2).
