Glycerol monolaurate was compounded in the absence of solvent under the reaction of lauric acid and glycerol with Nation - H as catalyst. The factors which affected the reaction was studied. The result showed that the optimum technical condition was the molar ratio （ acid ： glycerol） 1 ： 2.5, the ternperature 190 ℃ for 2 h, the mass ratio of catalyst to lauric acid and glycerol 1.5%, in this case glycerol monolaurate was 64.1%. The catalyst could be reused dispense with any treatment, which was good for industrial applications.
