Destruction of CFC113 in supercritical and subcritical water

Abstract

Destruction of 1,1,2-trichlorotrifluoroethane (CFC113) in supercritical and subcritical water was performed over a wide range of pressure at 673 K. The hydrolysis reaction of CFC113 in the supercritical water could lead to complete destruction of CFC113, while the CFC113 destruction below the critical pressure of water was quite low. The Cl- destruction yields were higher than those of F over the whole pressure range including both supercritical and subcritical regions, which implies that the bonding energy of F on the backbone of CFC113 is stronger than that of Cl. The destruction yields represented by two ions were found to have the linear dependency on the reduced water density.
