Octylic-acetoacetic Ester and its Derivatives. 



Sodacetoacetic ester treated with octylic iodid, Cs H I7 i, gives octy- 

 licacetoacetic ester, CH 3 CO CH (C 8 H I7 ) CO 2 C 2 H 5 , which boils at 

 280 to 282 and has a specific gravity of .9354 at 18.5. It yields the 

 two usual saponification products, methyl nonyl ketone CH 3 CO C H 2 

 (Cg H I7 ), which boils at 224 to 226, and octylacetic acid CH 2 (C 8 H I7 ) 

 CO 2 H which is capric acid which boils at 265 to 267 The barium 

 and calcium salts and ethyl ester of this acid were described. 

 Di-octyl-acetoacetic ester is formed by further treatment of the 

 monoctyl derivative with sodium and octyl iodid, it boils at 340 to 342 

 This upon saponification gives dioctylacetone, boiling at 325 to 330 

 and dioctylacetic or isostearic acid which melts at 37- 38 and boils at 

 270 to 275 under 100 m. m. pressure. The barium and silver salts 

 and ethyl ester were described.

Two New Syntheses of Ethyl=methyl=oxy=acetic Acid. 



(1) From ethyl-methyl ketone, C 2 H 5 CO CH 3 , by treating it with 

 hydrocyanic acid and then with hydrochloric acid, C (C2 H 5 ) (CH,) 

 (OH) C0 2 H, is produced. 



(2) From ethyl-methyl-acetic acid (active valeric) which was 

 obtained from ethyl-methyl-acetoacetic ester by saponification. CH 

 (CH 3 ) (C 2 H 5 ) CO 2 H boils at 170 to 175, when treated with bromin, 

 a brom-ethyl-methyl-acetic acid is produced and this with water gives 

 ethyl-methyl-oxy-acetic acid, C (C 2 H 5 ) (CH 3 ) (OH) CO 2 H.
