摘要
The photolysis of Cl-2 in the presence of Cl2O4 at 366 nm in the gaseous phase has been investigated at 303 K. The UV absorbance of the gas mixture has been recorded spectrophotometrically after each photolysis interval to monitor the reactant Cl2O4 pressure and determine quantitatively the chlorinated reaction products. A quantum yield for Cl2O4 consumption of 2.0 +/- 0.2 has been determined. The main reaction products are Cl2O7, Cl-2 and O-2, accompanied by small quantities of Cl2O6 and OClO. A mechanism involving ClO4 radicals formed in the Cl atom abstraction from Cl2O4 by Cl is proposed. (C) 1998 Elsevier Science S.A.
