O efeito do ultra-som em reações químicas
Recebido em 2/2/99; aceito em 16/6/99 THE ULTRASOUND EFFECT ON CHEMISTRY REACTIONS. Unusual chemical phenomenon associated with ultrasound is on account of cavitation effect. The ultrasound increase the rate and yield of chemical reaction on account of its ability to emulsify liquids. When the ultrasound is used in metallic catalyst reaction the activity of catalyst is increased because the ultrasound clean the surface of catalyst. Sonogels have a fine porosity and large specific surfacedoi:10.1590/s0100-40422000000200017 fatcat:4ortvswf3ves3kxx6g4juwghhq
