Of ALIPHATIC COMPOUNDS. 47 



quantity of /z-propylamine is formed from n-propio- 

 nitrite. 



The reduction of aromatic nitrites takes place with- 

 out the occurrence of secondary reactions. This is 

 illustrated in the formation of benzylamine from 

 benzo-nitrile and of phenyl-ethylamine from benzyl- 

 cyanide. 



3. Compounds Containing Sulphur. 



Mercaptans. Bunge ' electrolyzed the alkali salts of 

 mercaptans and observed the formation of disulphides 

 at the positive pole. In the case of the sulpho-com- 

 pounds, however, the free acids were regenerated. 



Sodium-isethionate. The same author also investi- 

 gated sodium isethionate, but could note the formation 

 of only the free acid at the positive pole. 



Methyl-sulphuric Acid. This acid, investigated by 

 Renard, 3 yielded hydrogen at the negative pole, while 

 formic acid, carbon dioxide, carbon monoxide, and 

 trioxy-methylene, besides free sulphuric acid, were 

 found present at the positive pole. 



Potassium - trichlor - methyl Sulphate. This com- 

 pound, electrolyzed by Bunge, 8 gave hydrogen and 

 alkali at the negative pole, at the positive pole
