On the absorption of ozone by organic solvents: the role played by gas transfer through the gas-liquid separation surface

The absorption of ozone by organic liquids (chloroform, heptane, and carbon tetrachloride) was studied in bubbling reactors and reactors without bubbling. After the “burning out” of solvent impurities reacting with ozone at high rates, a stationary regime was established with the ozone concentration different from that at the entrance of the reactor, which was indicative of the occurrence of a side reaction with ozone consumption. This reaction did not influence the results of the determination of the general unsaturation of the substances analyzed.
