Abstract

Oxidation of tetradecahydroundecaborate ion with manganese dioxide is considered. The influence exerted by the structure of the crystal lattice of manganese dioxide polymorphic modifications (α, β, γ, δ) on the MnO₂ activity in tetradecahydroundecaborate ion oxidation is analyzed. The decaborane yield reaches a maximum if MnO₂ prepared by the reaction of aqueous solutions of MnSO₄ and KMnO₄ under varied conditions has predominantly amorphous form (δ-MnO₂). Based on the experimental results, a new stoichiometry of the oxidation reaction is suggested, taking into account the influence of different activity of MnO₂ polymorphic modifications on the decaborane formation.

二氧化锰将十四水合十一碳六氢化钠氧化为十硼烷的具体特征

摘要

考虑用二氧化锰氧化十四氢加氢键。分析了二氧化锰多晶型物变体（α，β，γ，δ）的晶格结构对十四氢十一键不变氧化过程中MnO ₂活性的影响。十硼烷产率达到最大，如果MnO的₂通过的MnSO的水溶液的反应来制备₄和的KMnO ₄在各种条件下具有主要为无定形形式（δ-的MnO ₂）。基于实验结果，考虑到MnO ₂多态性修饰物的不同活性对十硼烷形成的影响，提出了一种新的氧化反应化学计量。
