Ozone and ozonides

However, drawbacks are the required high energy use as well as the toxicity and explosivity of ozone and ozonides. In past times, and also today, proposals for the improvement of safety and process control of ozonolysis have been claimed [28-31]. The carbonyl oxide is converted with water into a hydroperoxide, which reacts to an aldehyde and hydrogen peroxide [32]. The latter is used for the subsequent oxidation of the aldehyde group to the carboxylic acid group. It is claimed that an avoided formation of secondary ozonides makes the process safer and diminishes the amount of side products. 

Note Ozone attacks the respiratory system and reacts explosively with organic solvents at room temperature. All work with ozone and ozonides should therefore be conducted in a fume cupboard, protective goggles should be worn and only smM amounts used.
