Decomposition of Organic Liquids by Ultrasound

Abstract

In this article, an effect of ultrasound on chemical reactions is reviewed. The sonochemical reaction proceeds at a hot spot produced by cavitation of bubble, i. e., creation and collapse of a bubble in liquid. Temperature and pressure at the hot spot exceed 5000 K and 100 MPa, respectively, therefore, pyrolysis of solvent can occur. We present experimental technique and our recent results of sonochemical decomposition of organic liquids and synthesis of C₆₀ from liquid benzene.
