 Benzylacetoacetic Ester. 



Benzylacetoacetic ester was made by treating sodacetoacetic ester 

 with benzyl chlorid, it is CH 3 CO OH (CH 2 C 6 H 5 ) CO 2 C 2 H 5 , it has 

 a specific gravity of 1.083 at 18.4 and cannot be distilled. When 

 saponified methyl-phenylethyl ketone, CH 3 CO CH 2 (CH 2 C 6 H 5 ), 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-benzyj 

 /9-oxybutyric ester was produced.

 Allyl-acetoacetic Ester. 



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

 ferric chlorid, its specific gravity is .982 at 20? When saponified it 

 yields ally 1- acetone, CH 3 CO CH 2 C 3 H 5 , 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 I2o-i25, and 

 with metacetone boiling point &4 -86 Allyl acetic acid, CH 2 (C 3 H 5 ) 

 CO 2 H, also obtained from the saponification, when oxidized becomes 

 succinic acid. Nascent hydrogen converts allyl acetoacetic ester into 

 <7-allyl /9-oxybutyric acid.
