Conversion of Bcnzol-PJienol. 19 



Benzoylcarvacrylaminc : — 



N^C7H5 = CijHi9NO. 



To form this compound a gram of the base was treated 

 with an excess of benzoyl-chloride. Action took place imme- 

 diately with evolution of hydrochloric acid. Upon warming, 

 a further evolution of gas took place, and a crystalline mass 

 of a yellowish tint was formed. Upon treating the mass with 

 sodium carbonate it became white and was crystallized from 

 hot benzol in shining crystals. 



The crystals had the appearance of flat rhombs and feathery 

 aggregates, were insoluble in hot water, with difficulty soluble 

 in cold, easily in hot alcohol, but readily soluble in ether or 

 benzol. Melting point 102°. 



The analysis gave the following result : — 



0.2184 gr. substance gave 0.6455 gi"- carbon-dioxide, and 

 0.1500 gr. water, equal to 0.1760 gr. C. and 0.1666 gr. H.

Derivatives of Dicarvacrylamine. 



The Platinum Double Salt — (Ca, H^s NH . HCl),PtCl4 — 

 was prepared after the method used with the double salt of 

 dithymylamine. The product so obtained was more crys- 

 talline than the isomeric salt, and after thorough washing 

 and drying over sulphuric acid in vacuum, granular feathery 

 aggregates of a beautiful golden color were formed. 



The analysis of the salt dried at 100° gave the following 

 result : — 



0.2039 gr. substance gave 0.0464 gr. platinum.
