Methane chlorination
Web20 jul. 2024 · In ethane halogenation, a chlorine radical generated in the initiation step first reacts with ethane in a hydrogen abstraction step, generating H C l and an ethyl radical (part a above). Then, the ethyl radical reacts with another (non-radical) C l 2 molecule, forming the chloroethane product and regenerating a chlorine radical (part b above). WebThe invention relates to a process for separating out hydrogen chloride from a gas mixture forming in the chlorination of methane, which gas mixture contains unreacted methane, its...

Web31 jul. 2024 · A possible set of steps for the chlorination of methane follows: Reactions (1) and (2) involve dissociation of chlorine into chlorine atoms and the breaking of a C − H bond of methane to give a methyl radical and a hydrogen atom. The methyl radical, like chlorine and hydrogen atoms, has one election not involved in bonding.
WebMethane, chlorine, and recycled chloromethanes are fed to a tubular reactor at a reactor temperature of 490—530°C to yield all four chlorinated methane derivatives (14). Similarly, chlorination of ethane produces ethyl chloride and higher chlorinated ethanes.The process is employed commercially to produce l,l,l-trichloroethane. l,l,l-Trichloroethane is also …
Web22 jul. 2024 · The chlorination of dissolved amino acids can generate disinfection by-products (DBPs). To prevent the formation of DBPs, we examined the UV-induced degradation of tryptophan (Trp). In order to further understand the impact of UV disinfection on Trp, the effects of initial concentrations of Trp, pH, temperature, concentrations of … nsfa annual meetingWeb6 sep. 2013 · This paper shows that the chlorination of methane can be controlled to give any of the desired chloromethanes in high yield. This is of significance because CH 3 Cl, CH 2 Cl 2, CHCl 3, and CCl 4 are all important feedstocks or solvents and this is how they are produced industrially.
