Calcium benzoate was synthesized using rheological phase reaction. The complex was characterized by using elemental analysis and IR. The mechanism of thermal decomposition for calcium benzoate was studied by using TG, DTA, and IR. The thermal decomposition of calcium benzoate in nitrogen proceeded in two stages: first it decomposed to form CaCO 3 and organic compounds. The CaCO 3 decomposed to form CaO and carbon dioxide. The organic compounds obtained from decomposition reaction are mainly benzophenone. From this,the green synthesis route of benzophenone was defined. 二苯甲酮 苯甲酸钙 流变相法 热分解 绿色合成 benzophenone calcium benzoate rheological phase reaction thermal decomposition green synthesis TQ24 国家自然科学基金资助项目 （ 2 0 0 710 2 6 ） 2001-06-01 2021-04-01 6
