ABSTRACT:
The reaction gases from the chlorination of methane and preferably also methyl chloride, after removal of the HCl and drying, are subjected to the steps of partially condensing the dried stream of reaction gases at a pressure of 5-15 bars and at a temperature of 0.degree.-40.degree. C. which condenses the chloroform and the carbon tetrachloride; contacting the gaseous phase of the partially condensed stream of reaction gases in a countercurrent manner with a stream of liquid methyl chloride; recycling the stream of gases discharging from the contacting stream of liquid methyl chloride to the chlorination stage; and fractionating the contacting stream of liquid methyl chloride.
