Ethylanilin, C 6 H 5 .KH.C 2 H 5 . Anilin combines di 

 rectly with ethyl bromide, slowly at the ordinary 

 temperature, rapidly by the aid of heat, forming ethyl- 

 anilin hydrobromate, a crystalline substance, from which 

 the base can be separated by means of potassa. Color 

 less liquid ; becomes brown in contact with the air ; 

 boils at 240 ; and forms with acids, crystallizing, easily 

 soluble salts. 



Diethylanilin, C 6 H 5 .]S T (C 2 H 5 ) 2 . The hydrobromate 

 of this base is produced by direct combination of ethyl- 

 anilin with ethyl bromide. Colorless oil ; does not turn 

 brown ; boils at 213. 



/Iphenylammonium. The iodide, C 6 IP.N 

 (C 2 IF) 3 I, is formed by heating diethylanilin with ethyl- 

 iodide at 100, for a long time. Silver oxide produces 

 from this the hydroxide C 6 H 5 .N&quot;(C 2 II 5 ) 3 .OH, which is 

 strongly alkaline ; easily soluble in water ; and is resolved 

 into diethylanilin, ethylene, and water by distillation.

talline base, fusing at 57. 



A large number of analogous bases can be prepared 

 in the same manner, by allowing the bromides of other 

 alcoholic radicles to act on anilin. When aiiilin is- 

 heated with amyl bromide, for instance, amylanilin 

 C 6 H 5 .im.C 5 H 11 , is produced; this yields, with ethyl 



bromide, amylethylanilin C 6 H 5 .N j ^jp and, finally, 



if methyl iodide is allowed to act upon this, the iodide of 

 an ammonium is produced, in which each hydrogen 

 atom is displaced by a different radicle (phenylamyl-
