| Abstract: | Benzyl benzoate was synthesized with sodium benzoate and benzyl chloride catalyzed by ionic liquid catalyst Bmim]Cl/CoCl2. The influences of different conditions on the reaction were studied. The results showed that the optimal reaction conditions were: mole ratio of sodium benzoate to benzyl chloride 1.0:1.2, reaction temperature 100℃, reaction time 3 h, mole ratio of Bmim]Cl/CoCl2 to sodium benzoate 0.05:1. Under these conditions, the yield was up to 96.8%. |
