 Some Actions of Sodium and Sodethoxid. 



The difference is shown between treating sodethoxid with an alkyl 

 iodid and an alkyl acetate. 



In the first case sodium iodid is produced thus : 



Na ) , I I __ Na j C 2 H 5 



C 2 H 5 j C h C 2 H 5 j - I } +C 2 H 5 

 In the second case the sodium replaces the acetyl group and not the 

 ethyl. This could not be shown in acetic ester, therefore valeric ester 

 was worked with. It was treated with metallic sodium, reaction took 

 place and no gas was given off. 



The reaction was 2 C ^ H 9 1 + 2 Na= 2 ^ a w 1 O+ S 5 2 9 n f

Acetic Acid. 



Acetic ester was treated with sodium and Ce H 9 Na O 3 was produced. 

 By boiling with water it was decomposed into acetone, alcohol, carbon 

 dioxid and sodium carbonate. C& H IO O 3 was produced from its sodium 

 compound by treating with hydrochloric acid, carbon dioxid or acetic 

 acid, when it was called by the author ethyl-diacetic acid ; it has a 

 specific gravity of 1.03 at 5, boils at 180.8 and reddens litmus only 

 when water is added. In obtaining it some dehydracetic acid was 

 always formed. It has the composition Cg H 8 O 4 and melts at 108.5 

 and boils at 269.6. The barium and copper compounds of ethyl- 

 diacetic acid and the barium, sodium and calcium salts of dehydracetic 

 acid were described. Ethyl-diacetic ethyl C 8 H I4 O 3 produced by ethyl 

 iodid boils at 198 and colors ferric chlorid blue. Btttyl-diacetic methyl 

 C 7 H I2 O 3 boils at 186.8 has a specific gravity of 1.009 at 6 and colors 

 ferric chlorid a deep blue.

Synthetical Researches on Esters. Part I. 



Acetic ester was made from sodium acetate, alcohol and sulfuric 

 acid. It was treated with sodium when an action took place and hydro- 

 gen was given off. The product was treated with ethyl iodid and the
