摘要
Using castor oil and epoxy chloropropane(ECH) as the main raw materials under the alkali condition, a novel castor oil glycidyl ether (COGE) was synthesized through two steps, namely open loop and closed loop reaction. The effects of process conditions on epoxy values were investigated. The results showed that the highest epoxy value the product achieved was 1.56 mmol/g under the condition that the open loop reaction was set at 0.4% catalyst dosage, 3.5 molar ratio of ECH and castor oil, and reaction temperature at 60℃ for 5 h, and as well as the close-loop reaction was set 0.4% catalyst dosage, 1.1 molar ratio of NaOH and ECH, and reaction temperature at 60℃ for 6 h. The chemical structure of the castor oil glycidyl ether was characterized by FT-IR and 1H NMR. TGA analysis showed that castor oil glycidyl ether had good thermal stability at high temperature. Viscosity test showed that the product could reduce the viscosity of epoxy resin. ©, 2015, The Editorial of «Chemistry and Industry of Forest Products». All right reserved.
