CHLORAL* 787 



preparation of Dutch liquid, which had the composition 

 C 4 H 4 C1O, (4). It is named chlor ether al by him. It will be ob- 

 served that the fourth, first and third of these bodies are com- 

 pounds, in which 1,2 and 5 atoms of the hydrogen of chloride 

 of ethyl are replaced by chlorine, without any other change of 

 composition. They are all neutral bodies. 



Oxisulphuret of acetyl, C 4 H 3 S 2 O; a compound in which 2 

 atoms of the hydrogen of oxide of ethyl are replaced by 2 atoms 

 of sulphur, is obtained by the action of sulphuretted hydrogen 

 upon the oxichloride of acetyl. Another compound is formed 

 at the same time, in which 1 atom of chlorine remains, and only 

 1 atom of sulphur is introduced, C 4 H 3 C1SO. 



jdcetate of oxichloride of acetyl, C 4 H 3 C1 2 O+ A, a body formed 

 by the action of chlorine upon acetic ether, in which 2 atoms 

 of the hydrogen of the ether are replaced by 2 atoms of chlo- 

 rine ; or the oxichloride of acetyl is formed, and continues in 

 combination with the ace tic acid. The benzoate of oxide of 

 ethyl gives a compound, of which the formula is BzCl+C 4 H 3 

 C1 2 0. 



Chloroxalic ether, C 6 C1 5 O 4 or C 4 C1 5 O + C 2 O 3 ; formed by 

 the action of chlorine on oxalic ether, crystallizable, fusible at 

 291, not volatile. Cloroxamethane, C 6 Cl 5 O 4 -f C 2 O 2 ,NH 2 ; 

 formed by the action of ammoniacal gas on the ether, crystal- 

 lizable, fuses at 273 , boils above 392, volatile. Chloroxalovi- 

 nic acid is obtained by the action of solution of ammonia upon 

 chloroxamethane (Malaguti, An. de Chim. Ixxiv, 299). 



Chloride of acetyl, tyc. The following table exhibits the com- 

 position and some of the properties of the series of compounds 

 formed by Regnault, by treating the chloride of ethyl and the 

 products thus obtained, successively with chlorine (An. de Ch. 

 Ixxi, 353) :
