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 acetyl and oxygen, having less oxygen 

 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) C 4 H 6

 Researches Upon Monobasic Acids. 



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

 through. Sodium acetate and a compound *C I2 H 9 Na Oe were formed. 

 This compound was named dimethylen-carbonethylen ether sodium, as 



) OH 

 the author supposed it to be formed thus : 2 *C 2 H 2 , C 2 O 2 j OH,C 4 



* C 2 H 2 C 2 2 I Na O 



H 4 + 2 Na= C 2 H 2 , C 2 O 2 j H O, C 4 H 4 + C 4 H 5 Na O 2 + H 2 . By 

 treating this compound with ethyl iodid he formed dimethylen-carbon- 

 ethylen ether * de H I4 Oe, boiling at 198 with a specific gravity of .998 

 at 12 By using methyl iodid dimethylen-carbonmethylen ether 

 *C I4 H I2 O 6 boiling at 186.8 was produced. By the action of ammonia 

 on the former, two bodies were formed ; * de H I5 NO 4i insoluble in 

 water, melting at 59.5, and C I2 H n * NO 4 , soluble in water, melting 

 at 90 and subliming at 100 By passing carbon dioxid through * C I2 

 H 9 Na Oe, C I2 H IO Oe was produced. It colors ferric chlorid, a dark 

 violet. 

 *C = 6; = 8.
