Zusammenfassung:	The invention relates to a method for producing bifenthrin with a clean synthesizing process. Lambda-cyhalothric acid and 2-methyl-3-biphenylmethanol are adopted to react in a high-pressure kettle in the presence of a water-borne organic solvent and a catalyst, water generated in the reaction is moved out by the water-borne organic solvent, and a direct esterification reaction is carried out to obtain bifenthrin. The production method has the characteristics of high conversion rate of 2-biphenylmethanol, easily separated and recycled catalyst, small amount of three wastes in the synthesizing process and the like, and can meet the requirement of clean production.
