This embodiment provides a process for the azeotropic synthesis of bisphenol F diallyl ether using bisphenol F and 3-chloropropene. The preparation method includes the steps of dissolving 200.2 g of bisphenol F in 400 g of DMF, Add 138.2g of potassium carbonate and react at 100°C for 6h until complete reaction to produce phenate. And after the reaction, vacuum dehydration, add 175.5g of 3-chloropropene to the phenate after dehydration, Raise the temperature to 85°C and keep the reaction temperature for 7 hours. After stopping the reaction, filter the by-products. The unreacted 3-chloropropene and solvent are distilled out to obtain bisphenol F diallyl ether. After measurement, the mass of the product obtained is 281.6g, The purity of bisphenol F diallyl ether in the product was 89.33%.
