Ozone Reactions
Organic Compounds react with Ozone in a process similar to combustion.
The reaction of an organic compound with ozone and the combustion of the same compound yield carbon dioxide and water as the main end products. Ozone also combines with most of the Hetro-elements found in organic compounds to produce the elemental oxide with the highest oxidation number.
Inorganic compounds of lower oxidation numbers react with Ozone to produce oxides, however, there are many inorganic compounds which will not react.
The reactions are grouped according to the following classification:
This group breaks down into carbon dioxide, water and oxygen.
This group includes: Acetic Acid, Acetone, Formaldehyde, Isopropyl Alcohol. M.E.K (methyl ethyl keytone), Propylene Glycol.
