    Abstract: PURPOSE: A manufacturing method of glycerol carbonate using zinc catalyst and acid is provided to reuse the catalyst and to manufacture glycerol at high yield. CONSTITUTION: A manufacturing method of glycerol carbonate using zinc catalyst and acid is processed by reacting glycerol with urea. The Zn catalyst is ZnO or Zn alkoxy compound. The Zn alkoxy compound is a compound represented by chemical formula 1 or chemical formula 2. The acid is halogenated acid, inorganic acid or sulfonic acid. The halogenated acid is HF, HCl, HBr, HI, and the inorganic acid is HNO3, HNO2, and H2SO4. The sulfonic acid is toluene sulfonic acid(CH3PhSO3H), methanesulphonic acid (CH3SO3H), and trifluoromethane sulfonic acid (CF3SO3H). The reaction dose of the urea is 1- 5 times of the reaction dose of glycerol. The amount of the Zn catalyst is 0.1 - 5 mole% of the glycerol amount.
