Sturrock, M. G.; Lawe, T.; Can. J. Res.; Sect. B. 1939, 17, 71-74.
Variables:
Ambient temperature: 403.2 - 470.2 K
Prepared by:
Method/Apparatus/Procedure:
Melting points and freezing points were obtained by determining temperatures of incipient fusion and complete liquefaction using capillary tube method. Temperature very slowly raised and material observed through a low power microscope.
Source and Purity of Materials:
- Obtained from heavy crude oil, and was recrystallized from alcohol before use.
- Obtained from heavy crude oil, and was fractionally recrystallized from alcohol before use.
Estimated Errors:
Ambient temperature: T/K: precision ±0.5 (compiler). x1: ±0.005 (compiler).

(None) Binary system shows incomplete solid solution from circa x1 = 0.00 to x1 = 0.15, and from x1 = 0.71 to x1 = 1.00. Tin refers to the temperature at which crystallization begins; Tfin is the temperature at which crystallization of the solid solution concludes.
