Paragraph 0024-0027, (2017/02/02)
The invention discloses a preparation method of lactofen. The preparation method of lactofen comprises the following steps: carrying out esterification reaction on acifluorfen and 2-ethyl chloropropionate in an organic solvent in the presence of acid-binding agents, thereby obtaining the lactofen after complete reaction and aftertreatment, wherein the acid-binding agents are at least one of potassium hydroxide, sodium hydroxide, sodium tripolyphosphate, borax anhydrous, CaO, sodium metasilicate, sodium orthosilicate and sodium acetate. According to the invention, special acid-binding agents are selected for replacing potassium carbonate and triethylamine, so that carbon dioxide gas is prevented from generating; the reaction system is more stable; meanwhile, the emission of pollutants is reduced; the environment is protected.
