Notes:
Binary system shows incomplete solid solution from circa x

= 0.00 to x
1
= 0.15, and from x

= 1.00. T
in
refers to the temperature at which crystallization begins; T
fin
is the temperature at which crystallization of the solid solution concludes.
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:
(1) Obtained from heavy crude oil, and was recrystallized from alcohol before use.
(2) Obtained from heavy crude oil, and was fractionally recrystallized from alcohol before use.
Estimated Errors:
