Conversion of Bcjiaol-P/unoL 



Derivatives of Phenisamvlamine. 



The Platinum Double Salt — (Cu Hj^ N • H CI), Pt CI4 — 

 separated as a canary colored amorphous mass, when to a 

 hydrochloric acid solution of the base, platinum chloride was 

 added in slight excess. The amorphous floating mass was 

 dissolved with difficulty in hot water, more readily in hot 

 alcohol, and was crystallized from a hot mixture of the two 

 in beautiful golden needles. 



For the analysis, it was dried at ioo°-iio°, when it gave 

 the following result : — 



0.3464 gr. of the salt gave 0,0912 gr. platinum.

Phenisamylamine was treated with an excess of chlorben- 

 zoyl, and the reaction which commenced at once was fully 

 completed in an hour. During the operation a light-brown 

 crystalline mass separated, which was thoroughly washed, 

 mad« neutral with sodium-carbonate, and crystallized from hot 

 absolute alcohol. After a second crystallization, exquisite 

 crystals of a leaf-like form and a mother-of-pearl lustre shot 

 out from the solution in great abundance. These crystals, 

 which dissolved readily in hot alcohol and in cold chloroform 

 and benzol, had a constant melting-point of 148.5°. Calm ^ 

 gives the melting-point of the benzoyl-compound of his amido- 

 amyl-benzol at 146°- 149°.
