Action of Potassium and Sodium on Some Ethers. 



Potassium attacks acetic ester at once and is dissolved. No gas is 

 given off ; the mass solidifies and is found to be composed of potassium 

 ethoxid and a compound of acet}^ and ox3'gen, having less 0x37 gen 

 than acetic ester ; in other words the potassium abstracts oxygen from 

 acetic ester. The product obtained, treated with sulfuric acid, gives 

 acetic acid. The author decides that it is probably " Hypoacetous 

 acid " (unteracetylig-saure) C4 He Oiu.

 Researches Upon Monobasic Acids. 



Acetic ester was boiled with sodium and a stream of hydrogen passed 

 through. Sodium acetate and a compound *Ci2 Hg Na Oe were formed. 

 This compound was named dimethylen-carbonethylen ether sodium, as 



] OH 

 the author suppo.sed it to be formed thus : — 2 ^Cj H2, C2 O2 j 0H,C4 



^^ C2 H, C2 O2 I Na O 

 H4 + 2 Na= C2 H2, C2 O2 j H O, C4 H4 + C4 H5 Na O^ + H^. By 

 treating this compound with ethyl iodid he formed dimeth3'len-carbon- 

 ethylen ether * C16 H14 Oe, boiling at 198° with a specific gravity of .998 

 at 12° B3^ using meth3d iodid dimeth3den-carbonmethylen ether 

 *Ci4 H12 06 boiling at 186.8° was produced. B3^ the action of ammonia 

 on the former, two bodies were formed ; — * C16 H15 NO4, insoluble in 

 water, melting at 59.5°, and C12 Hi, * NO4, soluble in water, melting 

 at 90° and subliming at 100° By passing carbon dioxid through '•= C12 

 Hg Na Oe, C12 Hio Oe was produced. It colors ferric chlorid, a dark 

 violet. 

 *C = 6 ; = 8.
