 fied yields acetophenonacetone, CH3 COCH2 (CH2 COCe H5), from 

 which were produced two isomeric compounds CnHjoO, one of 

 which melts at 41 "-42°, boils at 235° to 240° and yields, on oxidation, 

 benzoic acid. The acid C12H10O3, previously described, gives by 

 oxidation benzoic, acetic and carbonic acids. An oil C12 Hg O3 C2 H5 , 

 was produced from this acid. The work is being continued.

Methyl=propyl=acetic Acid. 



This acid, produced from methyl-propyl-acetoacetic ester which was 

 made from methyl-acetoacetic ester and normal propyl iodid is proven 

 to be identical with the acid of the same name produced from saccha- 

 rose.
