Notes:
Compiler: Phase diagram shows formation of a 1:1 naphthalene - 2,4,6-trinitrophenol molecular compound. The two eutectic points occur at about x
1
= 0.059 and T/K = 382.6 and at
1
> 0.95 and T/K = 345.6.
Method/Apparatus/Procedure:
Phase diagram was determined using a thaw-melt method (described in detail in Rastogi and Nigam, Proc. Natl. Inst. Sci. India 1960, 26, 184).
