Original Measurements
Comish, R. E.; Archibald, R. C.; Murphy, E. A.; Evans, H. M.; Ind. Eng. Chem. 26, 397-406 (1934).
Variables:
Room Temp: 357 $\pu{K}$
Prepared by:
Method/Apparatus/Procedure:
The synthetic method was used. Determinations were made in test tubes, which were heated and allowed to cool slowly in air. Thermometers were roughly calibrated.
Source and Purity of Materials:
- Prepared from sodium cyanide and dimethyl sulfate; the crude product was distilled and successively washed with solid sodium hydroxide and $\ce{P2O5}$; carefully fractionated in a 6.09 m column; $d_{4}^{20}$ = 0.78215.
- Source not specified; commercial high-grade reagent.
Estimated Errors:
Ambient temperature: Not reported.
Mass concentration (m/v) (1): Not reported.
Components:
- Acetonitrile, $\ce{ C2H3N }$; [75-05-8] NIST WebBook
- Heptane, $\ce{ C7H16 }$; [142-82-5] NIST WebBook
Experimental Data
The upper critical solution temperature (UCST) was reported to be 84.0°C (357.2 K, compilers).
