Method/Apparatus/Procedure:

The synthetic method was used. The solutions of (1) and (2) were prepared by weight from glass syringes in 13-100 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%; shaken with concentrated H2SO4; washed with water; dried over CaSO4 and distilled at atmospheric pressure from CaH2.

Estimated Errors

Temperature: control to ±0.1 K
