Method/Apparatus/Procedure:
The synthetic method was used. Solutions of (1) and (2) were prepared by weight from glass syringes in 13mm×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-liter 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:
(1) Matheson, Coleman and Bell; practical grade; distilled at 57°C/12.9 kPa.
(2) Phillips; purity 99 mole %.
Estimated Errors:
Temperature: control to ±0.1 K
