OZONOLYSIS

Ozonolysis is a highly effective oxidation stage in organic process technology. A number of reactions of organic compounds with ozone and the production of ozonides are reviewed, e.g. ozonide formation, reaction of ozone to form aldehydes, di-aldehydes, carboxylic acids, etc. These reactions concern the use of ozone under special conditions i.e. fast kinetic reactions, highly inflammable and potentially explosive materials with a toxic gas. Based on practical experience in designing and operating ozonolysis systems, not just from the scientific view, the main operating parameters that must be considered when applying the process are discussed. These are shown to be the choice of solvent, the temperature of the process, the design of the reactor, the handling of aerosols,effects the residual ozone and the handling of off gases. Provided the correct chemical engineering approach is applied ozonolysis is an economic alternative in numerous chemical process.

Ozone is the only oxidant that can be used in a homogenous system that does not involve the addition of water . All the oxidant form, in addition to producing the desired product, by products which have to be separated from the product either immediately prior or subsequent to the following treatment stages. For example, hydrogen peroxide can only be used with water which may not be beneficial to the overall process if at some later stage it has to be removed . Ozonolysis is the name given to the reaction of ozone with organic compounds, dissolved in a solvent and whereby ozonides are formed.

Ozonolysis is the addition of the whole ozone molecule(O3) into the compound , i.e. all 3 oxygen atoms, it is not a substitution of an element or a molecule in the compound as is the case in the oxidant reactions. As such the process is exothermic and therefore implying that to maintain stable conditions an efficient cooling of the process is a prerequisite. The ozonides so formed are also on stable at low temperature and requiring that the reactor and subsequent process equipment be kept at temperature lower than the ozonide disintegration level.

Ozonolysis has been acknowledge as a highly effective oxidation stage in organic process technology for long time . However, the implementation of the ozonolysis process stage in a full-scale plant presents significant engineering problems that have to be solved. It is largely for this reason that the process has not been as widely applied as would expect ed when considering all the benefits that come with the use of ozone. Based on practical experience in designing and operating ozonolysis system this paper describes the main criteria that must be considered when applying the process in order to be successful. It also covers the handling and the safety aspects of using ozone, itself a toxic gas and always present in a greater volume of oxygen, under often special conditions i.e. materials having fast kinetic reactions, highly inflammable and potentially explosive. Provided the correct chemical engineering approach is applied ozonolysis can no longer be considered, an exotic process. It can be made safe and can be applied as an economic alternative oxidant in numerous chemical processes.
