The invention discloses a production process of
acetamiprid. The production process comprises the following steps: (1)
amination: adding a
solvent into an
amination reaction kettle, reducing the temperature, introducing a certain quantity of monomethylamine gas into the
solvent, controlling under certain temperature conditions, adding 2-chloro-5-chloromethylpyridine into the reaction kettle, reacting, increasing the temperature for amine
discharge, then reducing the temperature, filtering, filtering out
methylamine hydrochloride, removing the
solvent from a filtrate and transferring to the next step; and (2) condensation: controlling a material obtained from the above step under certain temperature conditions, dropwise adding ethyl N-cyanoethanimideate, reacting, reducing the temperature, filtering, obtaining the
acetamiprid,
drying, distilling a filtrate and recovering
ethanol. The production process disclosed by the invention is high in
amination reaction yield, simple in post-treatment, incapable of producing
wastewater, simple in
condensation reaction, high in yield and free from
wastewater production.
