 CONSTITUTION. 



Oxichlorocarbonate of oxide of methyl, C 4 H 3 C1O 4 ; considered 

 by MM. Dumas and Peligot as a compound of oxide of methyl, 

 and a particular acid, and represented by the formula :

PRODUCTS OF THE DECOMPOSITION OF METHYL AND 

 ITS DERIVATIVES. 



A compound belonging to the methyl series was obtained by 

 MM. Dumas and Peligot, which appears to correspond with 

 isethionic acid, by bringing anhydrous sulphuric acid in contact 

 with hydrate of oxide of methyl, observing to keep the mixture 

 cool. Its salt of barytes is crystallizable and has the same 

 composition as sulphate of oxide of methyl and barytes, but 

 does not agree with the latter in its chemical properties, and is 

 evidently a different substance. 



Under the influence of air, hydrate of oxide of methyl in 

 contact with platinum black undergoes oxidation, and forms an 

 acid, which is found to be pure formic acid. In this conversion, 

 2 atoms of hydrogen combine with oxygen and form water, and 

 2 atoms of oxygen are absorbed at the same time, and combine 

 with the remaining elements of the methyl, exactly as in the 

 conversion of alcohol into acetic acid :
