A method for synthesizing a chloroacetamide compound, metazachlor, in which 201.27 kg of a secondary amine compound A5 is dissolved in 2012.7 kg of an organic solvent cyclohexane.The temperature was raised to reflux, and 169.41 kg of chloroacetyl chloride was added thereto, and the reaction was refluxed for 6 hours. 80 kg of water was added for washing with water, and the mixture was allowed to stand for half an hour.The organic phase the solvent was removed to give the chloro acetamides 265kg (metazachlor), in 95% yield, 98.6% purity;The reactor was connected to a water absorbing apparatus of hydrogen chloride gas, and the hydrogen chloride gas generated in the reaction was absorbed by an aqueous ethanol solution having a mass concentration of 0.8% in the water absorbing apparatus, and the temperature of the water absorbing apparatus was controlled at 10 to 20 ° C to obtain industrial hydrochloric acid
