Decomposition of trichlorofluoromethane (CFC-11), which has been regarded as a cause of ozone destruction, was carried out by r.f.plasma. The decomposition of CFC-11 increased with input power of plasma, and decreased with gas flow rate of Argon. Products were soot, halogenated methanes and ethanes, molecular halogens etc. Addition of H<SUB>2</SUB>O made the decomposition increase as high as 100%. Both CO and CO<SUB>2</SUB> appeared by the addition of H<SUB>2</SUB>O, while both halogenated hydrocarbons and soot were extraordinarily decreased. Effect of O<SUB>2</SUB> addition was almost the same as that of H<SUB>2</SUB>O addition. Addition of H<SUB>2</SUB> affected no neither the decomposition nor depression of soot formation. Products distribution between halogenated ethanes and ethylenes, however, was affected by H<SUB>2</SUB> addition. Reaction pathways to products were discussed based on change in Gibbs energy.
