The complex was characterized by Elemental analysis, IR, X ray powder diffraction. It is monoclinic and has layered structure. The mechanism of thermal decomposition for manganese benzoate was studied by using TG, DTA, and IR. The thermal decomposition of manganese benzoate in nitrogen proceeded in one stage: it decomposed to form MnO, organic compounds and carbon dioxide. The organic compounds obtained from decomposition reaction are mainly benzophenone, triphenylmethane and so on. 苯甲酸锰 半固相反应 热分解 manganese benzoate semi solid phase reaction thermal decomposition O627.7 国家自然科学基金(61672102) 1998-06-01 2021-04-01 6
