The invention relates to a process for producing glycerol carbonate methacrylate, wherein the glycidyl methacrylate is reacted with the carbon dioxide in the presence of a catalyst and a solvent. Themethod is characterized in that the catalyst is potassium iodide, the solvent is acetonitrile, one or more mono-alcohols, or an arbitrary mixture of acetonitrile and one or more mono-alcohols, and thereaction of glycidyl methacrylate with carbon dioxide takes place at a pressure of 0.5 to 5 bar. 本发明涉及一种制备甘油碳酸酯甲基丙烯酸酯的方法，其中在催化剂和溶剂的存在下使甲基丙烯酸缩水甘油酯与二氧化碳反应，其特征在于所述催化剂为碘化钾，所述溶剂为乙腈、一种或多种一元醇，或乙腈与一种或多种一元醇的任何所需混合物，并且甲基丙烯酸缩水甘油酯与二氧化碳的反应在0.5-5巴的压力下进行。
