A mixture of strontium carbonate, hydroxide and oxide was prepared by thermal decomposition of SrCO3 and employed as catalyst in the decomposition of the chemical warfare agent simulant methyl paraoxon, by means of its transesterification with 1-propanol. The catalyst, which was characterized by N2 physisorption (BET method), temperature programmed desorption (CO2-TPD), Fourier Transform Infrared spectroscopy (FTIR), X-Ray diffraction (XRD) and Raman spectroscopy, promoted rate enhancements of the order of 107-fold in comparison to the spontaneous propanolysis reaction, the greatest catalytic effect promoted by metal oxide-based catalysts ever reported for this reaction. Compared to the fresh catalyst, the catalyst directly stored in the reaction solvent showed similar catalytic performance. Analysis of the reaction products by liquid chromatography with electrospray ionization mass spectrometry detection confirmed the transesterification of the substrate leading to dimethyl n-propyl phosphate, a product structurally related to a family of trialkyl phosphate flame retardants.

用于有机磷化学战剂模拟物脱毒的简单且高活性的锶基催化剂

碳酸锶、氢氧化锶和氧化物的混合物通过 SrCO3 的热分解制备，并用作化学战剂模拟物甲基对氧磷的分解催化剂，通过其与 1-丙醇的酯交换。该催化剂以 N2 物理吸附（BET 方法）、程序升温脱附（CO2-TPD）、傅里叶变换红外光谱（FTIR）、X 射线衍射（XRD）和拉曼光谱为特征，促进了 107 级的速率增强- 与自发丙醇解反应相比的倍数，这是迄今为止为该反应报道的金属氧化物基催化剂促进的最大催化效果。与新鲜催化剂相比，直接储存在反应溶剂中的催化剂表现出相似的催化性能。
