Abstract
The photochloriuation of methyl chloride has been studied at 2.4°, 25.0°, and 50.1 °C using absorbed light intensities of the order of 10−10 einstein cm−3 sec−1 and a wave length of 4358 Å. Chain termination was by chlorine atom removal but two mechanisms were operative. For the first, termolecular collisions, the evidence indicated somewhat different third-body efficiencies for methyl chloride, methylene chloride, and chlorine; the efficiency of SF6 was lower than for these by a factor of 6 to 9; the efficiency of HCl was, relatively, too small to measure. The second mechanism involved "sticky" collisions. Methylene chloride was particularly efficient in this process, indicating an unusually stable CH2Cl2–Cl complex.
