Preparation and Properties of Sodacetoacetic and 

 Sod=ethyIacetoactic Esters. 



Both these substances when anhydrous are soluble in ether but both 

 form hydrous compounds insoluble in ether. The anhydrous com- 

 pounds cannot be obtained by keeping the hydrous compounds over 

 sulfuric acid as has been stated and the author thinks that there is but 

 one form of anhydrous sodacetoacetic ester and not two, one of which 

 is insoluble in ether as stated by Michael.

Imido Esters and their Derivatives. 



Acetoacetic ester is treated with imidobenzoic ester and the chief 

 product is found to be phenylmethyl-hydroxypyrimidin,

melting at 216!' The imidobenzoic ester is probably first converted 

 into benzoic ester and ammonia thus: C6H5 C (NH) OC2H5 + H2 0= 

 C6H5 CO2 C2 H5-I-NH3 ; the ammonia acts on some imido-benzoic 

 ester forming alcohol and benzamidin which last product unites with 

 the acetoacetic ester.
