Abstract
A process for the ozonization of unsaturated organic compounds in a reaction column through which the unsaturated compounds--in solution in a protic solvent--and an ozone-containing carrier gas and an inert coolant are passed downward in co-current flow to provide for an improved coolant effect and an increased ozonization yield where the coolant comprises a compound gaseous or liquid at ambient temperature with a boiling point preferably in the range from +20.degree. C. to -200.degree. C. The boiling point of the coolant is preferably at least 5.degree. C. below the ozonization temperature.
