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.
