chlorine dioxide

The relative molecular weight is 86.905.

Boiling point 2℃, melting point-120.6℃.

It is brownish-yellow gas at room temperature, and can be condensed into reddish-brown liquid when the pressure is greater than its vapor pressure in the range of-100 ~ 15℃.

Methods: 1. Hypochloric acid dehydration.

Second, excess Cl2 reacts with HgO at-78 C..

It is unstable in gas, gradually decomposes at 3.8℃, and accelerates decomposition under the action of light. Liquids are sensitive to shocks. Usually decomposed into Cl2 and O2.

Crowe

Hypochloric anhydride

The molecular weight is 5 1.452.

It is prepared by the reaction of chlorine atoms and ozone.

Cl2O2

chlorine dioxide

The molecular weight is 102.904.

It is formed by the polymerization of two molecules of chlorine monoxide.

Under the action of light, it is decomposed into chlorine atoms and oxygen.
