Volume 77. Nitroalkanes with Water or Organic Solvents: Binary and Multicomponent Systems, p None
Original Measurements
Variables:
Room Temp: 289 - 306 $\pu{K}$

Method/Apparatus/Procedure:
The synthetic method was used. The solutions of (1) and (2) were prepared by weight from glass syringes in 13 mm x 100 mm Kimax screw cap culture tubes and sealed by a cap with a Teflon faced rubber liner. The tubes were suspended in a 3 L well-stirred water bath and cloud points observed visually. At least two observations were made of each set of samples, the first at a relatively fast cooling rate to find the approximate cloud point temperature and the second at a slow cooling rate to more precisely determine the cloud point temperature.
Source and Purity of Materials:
- Matheson, Coleman and Bell; practical grade; distilled at 57°C/12.9 kPa.
- Phillips; purity 99 mole%.
Estimated Errors:
Ambient temperature: control to ±0.1 K
Components:
- Nitroethane, $\ce{ C2H5NO2 }$; [79-24-3] NIST WebBook
- Hexane, $\ce{ C6H14 }$; [110-54-3] NIST WebBook
