ACTION OF CHLORINE UPON CHLORIDE OF METHYL. 835 



The combining measure of perchlorinated oxide of methyl 

 differs, it will be observed, from the other members of the series. 

 (Annales de Chimie, etc. Ixxi. 353). 



Chlorine is absorbed with great avidity by hydrate of oxide 

 of methyl and a heavy oil formed, which has not yet been fully 

 examined. 



Action of chlorine upon chloride of methyl. This also gives 

 rise to a series of compounds, in which the proportion of chlo- 

 rine increases as the action is prolonged. (Regnault).

The monochlorinated chloride of methyl has an odour which 

 is very sharp and is similar to that of Dutch liquid ; treated 

 with an alcoholic solution of potash, the former liquid gives 

 only a very trifling precipitate of chloride of potassium, and 

 distils over almost entirely without change. 



The perch loride of carbon, C 2 C1 4 , which is named above 

 perchlorinated chloride of methyl, is not altered by a solution 

 of hydrosulphuret of the sulphuret of potassium. It is decom- 

 posed by heat and gives different chlorides of carbon according 

 to the temperature. 



At a dull red heat, this chloride C 2 C1 4 appears to be con- 

 verted into another chloride of carbon C 2 C1 3 , supposing the 

 combining measure of the latter to be 4 volumes, its density 

 being 4082. This new chloride of carbon will therefore be 

 isomeric with Faraday's sesquichloride C 4 C1 6 , but of only half 

 the density. When decomposed at a higher temperature it 

 gives small silky crystals of the chloride of carbon of Julin CC1. 

 Lastly at a bright red heat the liquid chloride of carbon C 4 C1 4 

 is the principal product. 



Chlorine acts readily upon the sulphuret of methyl and upon 

 the compounds of oxide of methyl with acids or the compound 

 methylic ethers. A benzoate and acetate of an oxichloride of 

 formyl have been produced, having the following formula),
