| Abstract: | A method for synthesis of namyl lactate based on activated carbon supported phosphotungstic acid as catalyst was developed.The factors influencing the reaction were investigated through orthonormal experiments.The results show that the optimal condition is 1.8 g of catalyst and 5 mL of cyclohexane(to remove water) with the molar ratio of amylalcohol to lactic acid being 1.5 and the reaction time being 2 h.The yield of namyl lactate under such conditions is over 96.2%.The catalyst can be used repeatedly for many times without distinct loss in activity. |
