The decomposition of this acid and its salts by bromine and 
nitric acid is very striking ; the acid disappears and new in- 
soluble compounds are forme 
The action of bromine is expressed by the following equa- 
tion :

The trichlormethyl-sulphon-bromid is a white crystalline 
body of a faint acrid smell, insoluble in water but soluble in 
alcohol and ether. On the application of heat a part is sub- 
ed without change while another part is decomposed. Am- 
Monia dissolves it with evolution of nitrogen.

Soluble in ether and alcohol. Water added to the alcoholic 
Solution precipitates it unchanged. It does not melt in boil- 
: water but is volatilized with the steam. Ammonia dis- 
Solves it slowly with decomposition, alcoholic solution of caus- 
tic potassa decomposes it quickly. When it is trea with 
zinc and hydrochloric acid it disappears and is converted into 
Sulphydrate of methyl and ammonia : oe
