8 AET. 11. — T. YAMAMOTO : THE FUSION CUKVES 



Of the four constants in this equation the two, Q and To, 

 have been experimentally determined. The other two, Q and S, 

 may be deduced, when the degree of association of phenol at 

 different temperatures can be determined by any appropriate 

 method. But in default of other reliable data we are forced to 

 evaluate them from the fusion points of the system under con- 

 sideration. And this can be accomplished in the following manner. 



If 111 and 7^3 represent the nundjer of gramme molecules of 

 CßHeO and (C6H60)3 respectively, then 



«^4-3??., = N^ ...(8) 



and if we put 



îii + %= ')\, (9) 



we have 



C, = ^^ -, (10) 



and ^3 = 1 2. sj> ^^^^ 



From (U), (10), (11), and (6) 



3^ = -é^ (^1«) 



When the fusion point T is determined, (E is given by (6), and 

 9Î can be calculated. 

 From (8) and (9)
