Abstract

Described herein are method for conducting sonochemical reactions and processes in a liquid. The liquid is passed through a device that generates a liquid jet containing cavitation bubbles and collides the liquid jet with an impact body or other liquid jet to force the collapse of the cavitation bubbles at a select compressive stagnation pressure. The compressive stagnation pressure of the liquid is between 50 and 99 percent of the static pressure of the liquid upon entry of a constriction that generates the liquid jet containing cavitation bubbles.

Claims

1. A method of conducting sonochemical reactions or processes in a liquid comprising the steps of:

a. passing a liquid comprising an aqueous or organic liquid at static pressure P through a constriction of a device to form a liquid jet containing cavitation bubbles; and

b. subjecting the cavitation bubbles in the liquid jet to a compressive stagnation pressure, P_st, wherein P_st is P_st=(0.5−

0.99)P, by colliding the cavitation bubbles with an impact target downstream of the constriction within 1 millisecond or less of the liquid exiting the constriction.
