Method/Apparatus/Procedure:
(a) The solubility of (1) in (2) was determined by means of the formaldehyde-sulfuric acid reagent, ref (1). The value shown for 7°C is the mean of three determinations, and the value for 25°C is the mean of two determinations; all other data are single determinations only.
(b) The cloud point exhibited by this system appeared to be very sharp, as the samples passed from a state in which they were cloudy within 1°C. The cloud point data averages of from two to eight separate determinations. Cloud points at 0.025 g(1)/100 g solution were very faint.
Source and Purity of Materials:
(1) source not specified; fresh samples; used as received.
(2) not specified.
Estimated Errors:
Temperature: (b) ± 0.5°C (from two to eight determinations)
