SYSTEM NAPHTHALENE-CHLOEOBENZENE-PHENOL, ETC. 



19 



The fusion point of pure naphthalene was not observed, 

 since the same sample was used as in fusion curves No. 1 and 

 No. 8. 



In the above table m is the mixture of phenol and cliloro- 

 benzene in the ratio of 40.248 gramme : 4.135 gramme. 



P C 



P+C ' P+C 



= .9209 .-.0791 



X is the empirical molar fraction of naphthalene calculated with 

 the mean molecular weight of the mixture of phenol and cliloro- 

 benzene = 95.45.
