ACETO ACETIC ESTER 9 



acetovaleric ester. It boils at 200 to 202., colors ferric chlorid rose 

 violet, when treated with bromin and then alcoholic potash and then 

 hydrochloric acid, two acids are formed according to the amount of 

 bromin used. The acids resemble angelic and oxy-angelic acids.

 A New Ester of Acetoacetic Acid. 



Isobutyl-acetoacetic ester was formed which boils at 202 to 206 with 

 some decomposition ; its specific gravity is . 979 at o The ester dis- 

 solves sodium, and oxyuvitic acid can be made from it.

 Oxidization of Acetoacetic Ester. 



When acetoacetic ester is oxidized by potassium permanganate, 

 potassium acetate, potassium oxalate, alcohol and water are formed.
