Octylic=acetoacetic Ester and its Derivatives. 



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

 licacetoacetic ester, CH3 CO CH (Cs H17) CO, C^ H5, 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 CH3 CO C H, 

 (Cs H17), which boils at 224^ to 226°, and octylacetic acidCH2 (Cs H17) 

 CO2 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 

 monoctjd 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 EthyI=methyl=oxy=acetic Acid. 



(i) From ethyl-methyl ketone, C, H5 CO CH,, by treating it with 

 hydroc5^anic acid and then with hydrochloric acid, C (C2 H5) (CH3) 

 (OH) CO2 H, is produced. 



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

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

 (CH3) (C, H5) CO2 H boils at 170° to 175°, when treated with bromin, 

 a brom-ethyl-meth57l-acetic acid is produced and this with water gives 

 ethyl-methyl-oxy-acetic acid, C (C2 H5) (CH3) (OH) CO, H.
