 Mono= and Di-heptyl-acetoacetic Esters. 



Acetoacetic ester treated with heptyl iodid, C 7 H I5 i, and sodium 

 ethoxid forms heptyl-acetoacetic ester, CH 3 CO CH C 7 H I5 CO 2 C 2 H 5 , 

 a colorless oil which boils at 271 to 273 and has a specific gravity of 

 .9324 at 17. i. This was saponified and heptyl acetone, CH 3 CO CH 2 

 C 7 H I5 , boiling at 2i4-2i5, with a specific gravity of .829 at 17.7, 

 and heptyl-acetic acid, identical with nonyl acid, were produced. Di- 

 heptyl-acetoacetic ester was made in the similar way, and from this 

 methyl diheptyl carbin ketone (diheptyl acetone), CH 3 CO CH (C 7 

 H I5 ) 2 , and diheptyl acetic acid, CH (C 7 H I5 ) 2 CO 2 H, were produced.

Derivatives of Heptanes. 



Heptyl-acetoacetic ester was produced by the Conrad and Limpach 

 method, it boils at 250 to 260. When saponified it yielded methyl 

 octyl ketone, CH 3 CO CH 2 CH CH 3 



C 5 Hn, which boils at 196 to 198 



This formula was assigned to it because the heptyl bromide, C 5 H IX CH 

 Br CH 3 , was used to start with.

 tt-Methyl-hydroxy-succinic Acid. 



Acetoacetic ester treated with hydrocyanic acid and then with hydro- 

 chloric acid gives, CH 3 C (OH) CH 2 CO 2 H, 



CO 2 H a crystalline substance, soluble in water, 



alcohol and ether which melts at io8f It is the same acid as Demarc- 

 ay's oxy-pyrotartaric described in Compt. rend. 82, 1337. The barium, 

 calcium, potassium, silver, lead and copper salts were described. The 

 three isomeric acids of this formula were shortly discussed.
