Ethylanilin, C 6 H 5 .NH.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 .^"(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. 



Triethylphenylammonium. The iodide, C 6 1F.N 

 (C 2 H 5 ) 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(C 2 H 5 ) 3 .OH, which is 

 strongly alkaline ; easily soluble in water ; and is resolved 

 into diethylanilin, ethylene, and water by distillation. 



Ethylenediphenyldiamine, (C 6 H 5 ) 2 ^ 2 H 2 .C 2 H 4 , is 



produced, together with anilin hydrobromate, by boil- 

 ing ethylene bromide with an excess of anilin. Crys- 

 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 anilin is- 

 heated with amyl bromide, for instance, amylanilin 

 C 6 H 5 .KELC 5 H n , is produced; this yields, with ethyl

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