SYSTEM XAPHTHALENE-CHLOEOBENZENE-PHEXOL, ETC. 



9:-^ 



X is the empirical molar fraction of phenol calculated as 

 CoHoO. 



All the other symbols in this table have the same meanings 

 as those in the foregoing tables. Naphthalene was added in the 

 pressed form. The curve coincides fairly well with that observed 

 by T. Yamamoto.^^ 



The eutectic point is 0.15° higher than that in the curve 

 with naphthalene as the solid phase, this is due to the moisture 

 absorbed, since in the former case the observations took two 

 days, while in the present case they were completed in only a 

 few hours.

Since naphthalene and chlorobenzene in such proportions as 

 are given in Table 10 do not form solutions at ordinary tem- 

 peratures, naphthalene was first added in compressed form and 

 then a corresponding quantity of chlorobenzene by means of a 

 thin graduated pipette.
