WebA chlorine atom has an unpaired electron and acts as a free radical. 2. Chain propagation (two steps): a hydrogen atom is pulled off from methane leaving a primary methyl radical. The methyl radical then pulls a Cl • from Cl 2. This results in the desired product plus another chlorine radical. WebThe present invention provides processes for the production of chlorinated methanes via the direct chlorination of methane. The processes include a dehydrochlorination and/or chlorination step that converts up to 100% of the higher chlorinated alkanes in a process stream from the methane chlorination reaction into more highly chlorinated alkanes.

WebLight-induced gas phase chlorination at 25 ºC gives 45% 1-chloropropane and 55% 2-chloropropane. The results of bromination ( light-induced at 25 ºC ) are even more suprising, with 2-bromopropane accounting for 97% of the mono-bromo product. These results suggest strongly that 2º-hydrogens are inherently more reactive than 1º-hydrogens, by ...

"WebThe process of chlorination. As described above, in the chlorination of alkanes by free radical substitution, one or more hydrogen atoms in an alkane is replaced by a chlorine free radical. UV light is used as a catalyst and hydrochloric acid is also given off. For example, the substitution of methane using chlorine produces chloromethane. " - Chlorinated methane
