✦ Synopsis

The gas-phase photochlorination (A = 436 nm) of the 1 , l , l ,2-C2H2C1( has been studied in the absence and the presence of oxygen at temperatures between 360 and 420°K. Activation energies have been estimated for the following reaction steps:

The dissociation energy D(CC13CHCl-02) f (24.8 =t 1.5) kcal/mole has also been estimated from the difference in activation energy of the direct and reverse reactions

The mechanism is discussed and the rate parameters are compared to those obtained for a series of other chlorinated ethanes.
