1- Decanoyl- rac- glycerol was synthesized by glycerol and decanoic acid, via protected bi- hydroxy groups by boric acid. The catalyst and reaction time, which influenced the reaction, was studied, and the most favorable condition of synthesis was confirmed. Bacteriostatic circle method measured the minimal inhibition concentration,the result showed, under the experiment concentrations, 1- decanoyl-rac-glycerol had strong antibacterial capability, and it still had good stability under heat treatment （ 121℃, 30min） . t - Decanoyl- racglycero had good a...
