Methane reacts with chlorine to produce methyl chloride and hydrogen chloride. CH4 + Cl2 → CH3Cl + HCl Once formed, methyl chloride can be chlorinated in subsequent reactions to form methylene chloride (CH2Cl2), chloroform (CHCl3) and carbon tetrachloride (CCl4). In a methyl chloride production process a reactor is fed with methane and chlorine in a molar ratio of 5: 1 (methane: chlorine). In the process the chlorine is consumed in its entirety. The selectivity observed in the process is 4...
