On the possibility of realization of reactions in the regime of superintense bubble boiling

摘要

The possibility of occurrence of various chemical reactions during superintense bubble boiling due to the formation of shock waves and cavitation was demonstrated. More than 20 individual liquids, mixtures thereof, solutions of dyes and inducators, bromoform, etc., were tested. The formation of hydrogen peroxide during SBB in distilled water was investigated. It was demonstrated that the nature of the heater material plays an important role. A critical character of the dependence of the hydrogen peroxide yield on the power applied to the heater was revealed. SBB in aqueous solutions of ethanol was shown to produce high-boiling compounds, primarily ethyl cellosolve and acetyl cellosolve, according to chromatographic analysis. In the acetone-water system, polycondensation products, in particular, acetone dimers and trimers, such as isophorone, were produced.
