4 ELECTROLYSIS AND EL EC TROS YN THESIS 



1. In sulphuric acid solution: aldehyde, acetic 

 ester, formic ester, ethylidene oxy-ethyl ether 



CH^ H ) (Renard) and ethyl-sulphuric 



acid. 



2. Almeida and Deherain state that in the elec- 

 trolysis of a nitric acid solution they observed, in 

 addition to these oxidation products, carbonaceous 

 derivatives of ammonia at the negative pole. 



3. In hydrochloric acid solution, 1 chlor-acetic acids 

 occur in addition to the corresponding oxidation pro- 

 ducts (Riche 8 ). Habermann, on electrolyzing the 

 alcohol in alkaline solution, obtained, besides carbon 

 dioxide, an aldehyde resin (Ludersdorf 3 and Con- 

 nel 4 ) from which he isolated a body closely related 

 to cinnamic aldehyde. In aqueous solution, on the 

 addition of potassium acetate, the alcohol was split 

 up into ethane, potassium ethyl-carbonate, carbon 

 dioxide, and acetic ester. Also with propyl and 

 butyl alcohols, to which potassium acetate had been 

 added, analogous results were obtained by Haber- 

 mann. 



Exact statements regarding the strength of the 

 current are in no case given. In consideration of the
