 Benzylacetoacetic Ester. 



Benzylacetoacetic ester was made by treating sodacetoacetic ester 

 with benzyl chlorid, it is CH3 CO CH (CH^ Ce H5) CO^ C^ H5, it has 

 a specific gravity of 1.083 ^t 18.4° and cannot be distilled. When 

 saponified methyl-phenylethyl ketone, CH3 CO CHj (CH2 Ce H5), is 

 obtained, it boils at 235°-236° and has a specific gravity of .989 at 23. 5^ 

 When this ketone is oxidized acetic and benzoic acids, carbon dioxid 

 and water are produced. Dibenzylacetoacetic ester was also pro- 

 duced. The action of nascent hydrogen on benzylacetoacetic ester was 

 found to be analogous to that on acetoacetic ester, that is, a-benzy^ 

 /9-oxybutyric ester was produced.

AlIyl=acetoacetic Ester. 



Allyl-acetoacetic ester boils at 206° and gives a carmine color with 

 ferric chlorid, its specific gravity is .9S2 at 20.° When saponified it 

 yields allyl-acetone, CH, CO CH2 C. H5, which boils at 128° to 130° 

 and has a specific gravity of .834 at 27° It is isomeric with mesityl 

 oxid, boiling point I3i°-i32°; with dumasin boiling point i20°-i25°, and 

 with metacetone boiling point 84°-86.° Alhd acetic acid, CH, (C3 H5) 

 CO2 H, also obtained from the saponification, when oxidized becomes 

 succinic acid. Nascent hydrogen converts allyl acetoacetic ester into 

 a-allyl /J-oxy butyric acid.
