What is ozonolysis and its applications?

Question

Isaac Aronson · Accepted Answer

Ozonolysis is a redox reaction involving #"O"_3# and alkenes. An important application is the synthesis of ketones.

In the presence of oxidising agents, alkenes can turn into alcohols, aldehydes, ketones or carboxylic acids.

In ozonolysis, ozone (#"O"_3#) is bubbled through a solution of the alkene in methanol at −78 °C, until the solution turns blue (which is due to excess unreacted ozone).

The intermediate formed at the end of the ozonolysis reaction is called an ozonide. To obtain the ketone/aldehyde products, zinc or dimethyl sulfide (reducing agent) is added.

A general overall reaction is shown below.

undefined Ozonolysis is a chemical reaction where ozone (O3) is used to cleave double or triple bonds in organic compounds. This reaction often leads to the formation of smaller molecules, aldehydes, ketones, or carboxylic acids.

Applications of ozonolysis include:
- Organic synthesis in laboratory settings
- Degradation of pollutants and organic compounds in wastewater treatment
- Production of ozone for disinfection purposes in water treatment
- Decomposition of organic matter in food processing industries
