β¦ Synopsis
Long-chain chlorine-photosensitized oxidation has been observed in the gas phase at about 355'K for 1,1,2,2-and 1,1,1,2-C~H~C14, CZHClS, and CzC14 but not for CzHe, 1,2-CzH4C12, I,l,I-C2H3C13, CzH4, and 1,2-CzHzCIz. This is shown to depend on the exothermicity of the dissociation of the chloroethoxy radicals which must be involved in each reaction system.
