Upon «i-«2-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, 



CH2 — CH(CH3 C0)C02 C2 H5 

 which is I .It will unite with phenyl- 



CH2 — CH(CH3 C0)C02 C, H5 



hydrazin, one molecule of (C6H3N2H)" displacing each atom of oxygen 



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



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



sulfuric acid and alcoholic potash are given.

5o=called Carbacetoacetic Ester. 



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

 that of sulfuric producing an anhydrid, C18 H22 O9 , which breaks down 

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

 so that Duisberg's so-called carbacetoacetic ester, Cs Hio O3 » must be 

 isodehydracetic ester, do Hj, O4 .
