• 中文摘要： 本文主要係研究鈷型不均勻化均勻觸媒催化苯甲醛合成過氧苯甲酸之水和惰性固體表面效應。實驗結果顯示惰性表面很明顯地降低了過氧苯甲酸的生成速率。實驗求得鈷型不均勻化均勻觸媒的水合數和水合平衡常數分別為 2.92和1.92×10/sup 6/M/sup -2.92/。實驗中除分別求得相關的動力學參數外,也求證了各反應速率表示式。除此之外,本文也提出了在水和惰性固體表面影響存在下,不均勻化均勻觸媒催化苯甲醛合成過氧苯甲酸的反應機構。實驗證實理論分析與實驗結果相當吻合。
• 英文摘要： The effects of water and inert surface on the oxidation of benzaldehyde using heterogenized homogeneous Co(III) as catalyst were investigated. The results show that the inert surface and water significantly slow down the reaction rate of producing perbenzoic acid. The hydration number and equilibrium constant of hydration of heterogenizing homogeneous Co/sup3+/ were 2.92 and 1.92 x 10/sup 6 /M/sup -2.92/,respectively. The kinetic parameters were experimentally found. The rate equations of this system were also obtained. The reaction mechanism of catalytic oxidation of benzaldehyde in the presence of water and inert surface was proposed. The theoretical analysis correlated well with experimental results.
