O ELECTROLYSIS AND ELECTROS YNTHESIS 



70$. Sodium iodide remains in the mother-liquor as 

 the principal secondary product. 



Chloroform and Bromoform are formed if the chlo- 

 ride or bromide of the alkalies is used (comp. Elbs 

 and Herz, 1 who deny this*). Analogous to these sub- 

 stitution reactions is the formation of aristol? a di-thy- 

 mol-di-iodide, as made by Messinger and Vortmann, 9 

 by the electrolysis of thymol with the addition of 

 potassium iodide. Similar to this also is the pre- 

 paration of nosophene, a tetra-iodo-phenol-phthalein 

 (Classen and Lob 4 ). 



Glycol. Of diatomic alcohols only glycol seems to 

 have been the subject of investigation. Renard 6 

 observed in the electrolysis of a sulphuric acid solu- 

 tion of glycol, besides the formation of hydrogen, 

 carbon monoxide, carbon dioxide, and oxygen, that 

 trioxy-methylene, glycolic acid, formic acid, and a 

 substance isomeric with glucose were present in the 

 solution. 



Ethylene Glycol under similar conditions gives the 

 same products (Renard 6 ). 



Glycerine. Renard "also investigated the behavior
