The invention discloses a method for preparing 2-fluoropropionate, comprising: reacting 2-chloropropionate, hydrogen fluoride and a catalyst according to the quantity ratio of 1:1.2-1.5:0.01-0.02 under 50-200 DEG C for 20-30h, cooling, separating liquid and rectifying after reacting to obtain the 2-fluoropropionate product. The invention has the advantages of high reaction yield, good selectivity of the product, low production cost and little generation amount of three wastes (waste gas,waste water and industrial residue). The reaction yield can reach up to 83.2%, and the highest selectivity of the 2-fluoropropionate is up to 87.5%. |
