苯甲酸钡的热分解机理

THERMAL DECOMPOSITION MECHANISM OF BARIUM BENZOATE

碱土金属苯甲酸盐是一类比较稳定的化合物，对其已有的报道主要涉及含结晶水碱土金属苯甲酸盐的红外光谱和热分解过程，这些热分解仅涉及失水过程和固体残留物的分析［１～３］。我们首次用半固相法合成了苯甲酸钡，并对无水苯甲酸钡在氮气中热分解的气相凝聚物进行了分析...

; Barium benzoate was synthesized in semisolid phase reaction. The complex was characterized by elemental analysis, IR, Xray powder diffraction. It is layered structure, monoclinic system. The mechanism of thermal decomposition for barium benzoate was studied by using TG, DTA, IR and gas chromatographymass spectrometer. The thermal decompositon of barium benzoate in nitrogen proceeded in one stage: it decomposed to form BaCO\-3 and organic compounds. The organic compounds obtained from decomposition reaction are mainly benzophenone, triphenylmethane and so on.\=\;
