Abstract

The effect of equipment corrosion products (transition metal cations) on the physicochemical and catalytic properties of a homogeneous Pd(II)+HPA-x (Mo–V–P heteropoly acid containing x vanadium atoms) catalyst developed for the two-stage oxidation of n-butene to methyl ethyl ketone (MEK) with oxygen has been studied. The thermal stability of a solution of a catalyst based on HPA-x in the presence of transition metal cations has been determined. The composition of the two-component catalyst recommended for pilot testing of the MEK process has been optimized.

基于杂多酸溶液的均相氧化还原催化剂：IV。甲基乙基酮合成催化剂在设备腐蚀产物（金属阳离子）存在下的试验

摘要

设备腐蚀产物（过渡金属阳离子）对 Pd(II)+HPA - x（含x 个钒原子的Mo-V-P 杂多酸）催化剂的物理化学和催化性能的影响，该催化剂用于两阶段氧化已经研究了正丁烯与氧合成甲基乙基酮 (MEK)。已经确定了在过渡金属阳离子存在下基于 HPA- x的催化剂溶液的热稳定性。推荐用于 MEK 工艺中试的双组分催化剂的组成已经过优化。
