摘要
The higher chloromethanes, i.e., CH2Cl2, CHCl3 and CCl4, are simultaneously produced by chlorinating methyl chloride with chlorine in a first reaction zone A, chlorinating at least one of the higher chloromethanes CH2Cl2 and CHCl3 with chlorine in a parallel second reaction zone B, combining the reaction products from said first and said second reaction zones A and B, separating higher chloromethanes from said combined reaction products, and recycling at least one of said separated higher chloromethanes CH2Cl2 and CHCl3 as chlorination feed to said second reaction zone B.
