48 BIBLIOGRAPHY OF 



C 2 H 5 . Attention is called to the colors produced by acetoacetic com- 

 pounds and phenol compounds with ferric chlorid as indicating by 

 their similarity that these bodies are similarly constituted. Comment 

 is made upon changing the fatty acid into the benzene ring as pointed 

 out by Wedel, that is, acetic ester into acetoacetic ester and this into 

 quinonehydrodicarboxylic ester and this finally into hydroquinone.

 Acetoacetic Acid in Urine. 



The author states that he published a paper in 1880 identifying 

 acetoacetic acid in urine, he therefore claims priority to Tollens f (Ber. 

 14, 2594).

 New Synthesis of Quinolin Derivatives. 



By varied conditions a reaction between acetoacetic ester and anilin 

 is obtained which forms the compound CH 3 C (NC 6 H 5 ) CH 2 CO 2 C 2 H 5 , 

 which is very unstable. If the reaction be interrupted by adding sul- 

 furic acid, f oxy-a-methyl quinolin is obtained, which comes from the 

 compound cited above by its losing alcohol thus : CH 3 C (NC& H 5 ) CH 2 



N= CCH, 



CO 2 C 2 H 5 =C 6 H 4 < | +C 2 H 5 OH. It melts at 222 The 



C(OH) :CH 



intermediate anilin-acetoacetic acid, CH 3 C (NC 6 H 5 ) CH 2 CO 2 H, was 

 also obtained.
