摘要

在无有机溶剂条件下，使用 30% 过氧化氢将环己酮和/或环己醇氧化成己二酸的过程中，研究了两个系列的凯金型杂多化合物 H3-2xMnxPMo12O40 和 (NH4)3-2xMnxPMo12O40 (x = 0.25-1.5)的催化特性。通过气相色谱-质谱分析，确定了主要产品和副产品。H1.5Mn0.75PMo12O40 和 (NH4)2Mn0.5PMo12O40 化合物的己二酸产量最高。

Catalytic properties of two series of Keggin-type heteropolycompounds, H_3–2xMn_xPMo₁₂O₄₀ and (NH₄)_3–2xMn_xPMo₁₂O₄₀ (x = 0.25-1.5), have been studied in the process of oxidation of cyclohexanone and/or cyclohexanol to adipic acid, using 30% hydrogen peroxide, in the absence of organic solvent. The main products and by-products have been identified by means of GC-MS analysis. The highest yields of adipic acid are found in the case of H_1.5Mn_0.75PMo₁₂O₄₀ and (NH₄)₂Mn_0.5PMo₁₂O₄₀ compounds.
