The synthesis conditions of eleostearic glycidyl ester ( EGE ) were investigated by two -step method, and the product was confirmed by FT-IR. The results showed that the yield of eleostearic po-tassium could reach 81% under the conditions of tung oil 40 g, potassium hydroxide dosage 8. 5 g, reac-tion time 2 h, with 90% methanol as solution;the yield of EGE could reach 92% and its epoxy value was 4 . 7 ( close to the theoretical value 4 . 8 ) when molar ratio of eleostearic potassium to epoxy chloropropane and reaction time were 1∶4 and 4 h, respectively.
