chloride. With each were used twenty grams of phenol, 

 sixty grams of the bromide or chloride of zinc and ammonium, 

 and twenty grams of ammonium bromide or chloride, and the 

 temperature was maintained at 320°-330° for forty hours. 



Derivatives of Diphenisobutylamine. 



The Platinum Double Salt — (CooHogNH . HCl),Pt.Cl,— 

 was most readily obtained by adding to an alcoholic solution 

 of the hydrochloric acid salt an alcoholic solution of platinum- 

 chloride. An oily salt separated at first, which after standing 

 changed to a granular golden-brown mass. 



The mass was with difficulty soluble in water, but dissolved 

 readily in hot alcohol, from which it crystallized in golden 

 needles. The twice-crystallized salt was dried over sulphuric 

 acid in vacuum and at 1 10°, then analyzed with the following 

 result : - — 



L 0.3300 gr. of the salt gave 0.0670 gr. platinum ;
