Later Drechsel ' electrolyzed normal capronic acid 

 with alternating currents. The electrolytic solution 

 contained, in a volume of 3 liters, 200 g. of capronic 

 acid as magnesium salt and was nearly saturated with 

 acid magnesium carbonate. Platinum electrodes were 

 used. At the end of the experiment the following 

 compounds could be identified in the solution: 



1. Valeric acid. 5. Adipic acid. 



2. Butyric acid. 6. Oxy-capronic acid. 



3. Oxalic acid. 7. Glutaric acid. 



4. Succinic acid. 



In a still later research on the electrolysis of pheno 

 with alternating currents Drechsel 2 detected phenyl- 

 sulphuric acid, dioxy-benzenes, a number of acids of 

 the fatty acid series, arid in addition to these an oil 

 which he identified as hydro-pheno-ketone,

and whose phenylhydrazine compound he was able to 

 isolate. Drechsel regards the hydro-pheno-ketone as
