Integration of Photo-catalysis of Ultraviolet Rays for Chlorination Process of Methane Conversion into Mono-, Di-, Tri- and Tetra-Chloromethane
Abstract: Alkanes the most basic of all organic compounds undergo very few reactions due to its stability. One of the reactions is halogenation, or the substitution of single hydrogen on the alkane for a single halogen to form a haloalkanes. Example of this halogenation of alkanes is the chlorination processes. It is well established that methane-chlorine mixture undergoes substitution reaction at the temp of about 400ºC and presence of light without …
