The mother liquor contained the nitraniline chlorhydrate. 

 The nitraniline was precipitated by sodium hydrate and, after 

 purification, used again. 



The reaction is exactly analogous to the one representing 

 the formation of trinitroaniline (loc. cit.).

Solubility.— Almost entirely insoluble in hot water, coloring it 

 yellow, however: hardly soluble in boiling ether, carbon disul- 

 phide, carbon teti form, and absolute alcohol. 



Insoluble in chlorhydric, nitric (dil.) and sulphuric (dil.) acids. 

 Easily soluble in concentrated sulphuric acid to a deep red wine 

 color,* and is separated unchanged in the form of yellow flocks 

 on the addition of water. In aniline it is easily soluble with a 

 beautiful red color. In hot amyl-alcohol it is easily soluble, 

 but crystallizes badly therefrom. In hot glacial acetic acid it 

 is easily soluble, and separates in the form of a beautiful 

 orange-red crystalline sand. From a solution in acetylchlonde 

 it crystallizes in small wine-yellow transparent crystals. 



Aqueous ammonia dissolves it very easily, the solution 

 attaining a splendid scarlet-red color. By evaporation it 

 separates unchanged. In weak aqueous solutions of alka- 

 lies it behaves as with ammonia. Concentrated solutions of 

 sodium and potassium hydrates, especially by heating, decom- 

 pose it with evolution of ammonia. 



Properties.— Y\, 3ts of a heavy, crystalline, 



yellow sand, fusing at 205° to a red liquid which, when undis- 

 turbed, solidifies at about 175°. By careful heating it vola- 

 tilizes in the form of a yellow powder. It burns with a yellow 

 ami nous flame when heated on a platinum foil, and leaves a 



porous coal. If it be thrown on a hot surface i
