 Upon ^-oLj-Diacetyl-adipic Acid. 



From the high-boiling residue from the action of ethylene bromid on 

 sodacetoacetic ester the authors have isolated di-acetyl-adipic ester, 



CH 2 CH(CH 3 CO)CO 2 C 2 H 5 



which is I .It will unite with phenyl- 



CH 2 CH(CH 3 CO)CO 2 C 2 H 5 



hydrazin, one molecule of (C6H 5 N 2 H)" displacing each atom of oxygen 

 of the carbonyl groups. Ethylene-di-methyl-oxyquinizin is also 

 formed. The actions of diacetyl-adipic ester with alcoholic ammonia, 

 sulfuric acid and alcoholic potash are given.

 So-called Carbacetoacetic Ester. 



The action of hydrochloric acid on acetoacetic ester is the same as 

 that of sulfuric producing an anhydrid, dg H 22 O 9 , which breaks down 

 into isodehydracetic acid and its ethyl ester (as shown by Hantzsch) 

 so that Duisberg's so-called carbacetoacetic ester, Cg H IO O 3 must be 

 isodehydracetic ester, C IO H I2 O 4 .
