Derivatives of Carvacrylamine. 



The Platinum Double Salt — (Cjo H13 NH^. HCl)o Pt CI4 — 

 was made by precipitating a hydrochloric acid solution of the 

 amine with platinum-chloride. A yellow precipitate in the form 

 of needles shot out at once from the golden-colored solution. 

 These needles were recrystallized from alcohol in beautiful 

 prisms, grouped in clusters. The crystals were dissolved with 

 difficulty in hot water, but readily in hot alcohol and benzol. 



An analysis of the salt dried at ioo°-i 10° gave the follow- 

 ing result : — 



0.5024 gr. substance gave 0.1384 gr. platinum.

was formed readily by the action of acetic anhydride upon 

 a calculated amount of the base. Action began at once, the 

 solution became quite brown in color. To insure complete 

 reaction, the substances were warmed for an hour at 130°. 



The white mass which separated was crystallized from a 

 mixture of alcohol and water in glistening white plates — 

 melting at 115°. The crystals dissolved in an abundance of 

 hot water, more readily in benzol than in ether, with readi- 

 ness in hot alcohol.
