are formed as chief products the ethyl esters of a

It has been found on further investigation l that 

 besides the strongly dextrorotary unsaturated acid 

 designated as allocampholytic acid, C 8 H 13 COOH, an 

 isomeric acid is formed which, although slightly 

 dextrorotary as obtained, is perhaps even laevorotary 

 in an entirely pure condition. The latter on being 

 heated to 200 splits off carbon dioxide and yields a 

 hydrocarbon, C 8 H 14 , which boils at 120-122 and 

 appears to be identical with laurolene, made from 

 camphoric acid. 



A ketonic acid, C 8 H 3 O.COOH, melting-point 228, 

 is also found as an additional product of the electroly- 

 sis of potassium allocamphoric ethyl ester. The 

 authors conclude from their observations that cam- 

 phoric acid contains the group 

 H
