a new Product of Decomposition of Dinitrobenzole. 323 



skin in no less degree than carbazotic acid, nitrophenesic 

 acid, &c. ; but it does not afford the beautiful reaction with 

 hypochlorite of lime which characterizes aniline. 



Nitraniline displaces none of the metallic oxides from their 

 acid compounds ; its basic properties are exceedingly weak. 

 Aniline displaces this base from all its salts. 



Compounds of Nitraniline. 



Although nitraniline is so weak a base, it combines with 

 acids, affording crystallizable salts, which possess the same 

 constitution as the corresponding salts of aniline. All its salts 

 are decidedly acid to test papers. They are decomposed by 

 the caustic and carbonated alkalies, nitraniline separating in 

 a crystalline form. We have investigated the subjoined salts 

 in order to be completely satisfied with respect to the com- 

 position and nature of the base.

Hydrochlorate of Nitraniline, Ci 2 < j^q >N, HC1. — It is 



obtained by evaporating a solution of nitraniline in hydro- 

 chloric acid. The colour of nitraniline entirely disappears in 

 this solvent, and fine scales are obtained, shining like mother- 

 of-pearl, This salt is extremely soluble in water and alcohol. 

 Analysis. — 0*4055 grm. of salt gave 0*3350 grm. chloride 

 of silver, or 20*37 per cent of chlorine.

Binoxalaie of Nitraniline^ X A N ^ J-N,HO,2(C 2 3 ,HO). 



— This salt is obtained on mixing a solution of nitraniline in 

 alcohol with oxalic acid dissolved in the same solvent. This 

 salt separates in the form of yellowish crystals, which are 

 washed with ether and dried upon a porous tile. 



The combustion of this compound with chromate of lead
