Dichloro monoxide is a chemical compound from the group of oxides and was first obtained in 1842 by Gay-Lussac by reacting chlorine with mercury (II) oxide .
Extraction and presentation
Dichloromonoxide can be obtained by reacting mercury (II) oxide with chlorine.
properties
Dichloromonoxide is a yellow-brown (deep brown as a liquid), unpleasantly strong-smelling gas that is readily soluble in water with the formation of hypochlorous acid . It can only be stored in liquid or solid form at or below -78 ° C. It is sensitive to shock and decomposes in light. It explodes when it comes into contact with organic matter. It forms hypochlorites with alkalis . When diluting a saturated solution, hypochlorous acid is formed .
