Abstract

A hypothesis of mechanochemical instability of water (MCIW) is considered. It assumes that under ordinary conditions weak hydrogen bonds in water form Н₂О clusters so strong that the flows with a velocity gradient can break covalent Н—ОН bonds in these clusters, which results in occurrence of Н^• and ОН^• radicals and formation of Н₂О₂ and Н₂ molecules. This is a pure structural effect; therefore, the substances that strengthen the water structure (MgSO₄ salt, inert gases) considerably contribute to its enhancement. An increase in temperature and/or pressure diminishes the effect, weakening the water structure and determining limits of MCIW applicability. It is assumed that the MCIW mechanism can be an important element of the global hydrogen peroxide flow on the Earth. Applications of MCIW to sonolysis, mechanical activation, and formation of active water microdroplets are demonstrated.

水的机械化学不稳定性及其应用

摘要

考虑了水的机械化学不稳定性（MCIW）的假设。它假定通常的条件在水中形式的弱氢键下Н ₂ О簇如此强烈，以致在具有速度梯度流动可以打破在这些簇共价Н-ОН债券，这导致Н的发生^•和ОН ^•自由基和形成的Н ₂ О ₂和Н _2个分子。这是纯粹的结构效果；因此，增强水结构的物质（MgSO ₄盐，惰性气体）大大有助于其增强。温度和/或压力的增加会减弱影响，削弱水的结构并确定MCIW适用范围。假定MCIW机制可能是地球上全球过氧化氢流量的重要因素。证明了MCIW在声分解，机械活化和活性水微滴形成中的应用。
