Solubility.— The substance is insoluble in water, alcohol and 

 ether. Difficultly soluble in boiling glacial acetic acid. It is 

 soluble in an excess of boiling chloroform, separating in small 

 yellow crystals. _ o# 



Properties. — Small glittering yellow crystals, fusing at 189 

 to a red liquid. With alkalies' it behaves in the same manner 

 as the trinitrophenylparanitraniline. 



Dinitrophenylparanitraniline. 



Preparation.~The calculated amounts of diuitrobrombenzol 

 and paranitraniline were treated as in the production of the 

 preceding compound. On cooling the tube contained a mass 

 of dark-red crystals. They were washed with dilute alcohol. 



Analysis.— As the substance did not crystallize from any 

 solvent, it was purified by solution in glacial acetic acid and 

 thm by water. In this manner, bright yellow flocks 

 were obtained. After three repetitions of the solution, precipi- 

 tation, and washing, the substance was dried at 100 and 

 analyzed.
