Part of the ethylene dibromide adsorbed on wheat underwent decom- 
position to ethylene glycol and inorganic bromide on heating. The glycol 
reacted to a small degree with the protein, probably the -SCH3 of methio- 
nine (176). 
Ethylene Oxide 
Propylene Oxide 
Under conditions used for fumigation of foodstuffs, ethylene oxide 
and propylene oxide can combine with moisture to form the glycol. In the 
presence of inorganic chloride of foodstuffs, the corresponding chloro- 
hydrins were formed (1685, 1686).
