Ultrasonic Sonochemistry Equipment for Hemical Reactions And Processes


What's the theory of ultrasonic sonochemistry? 

 Sonochemistry is the application of ultrasound to chemical reactions and processes. Ultrasound is the part of the sonic spectrum which ranges from about 20 kHz – 10 MHz and can be roughly subdivided in three main regions: low frequency, high power ultrasound (20 – 100 kHz), high frequency, medium power ultrasound (100 kHz – 1 MHz), and high frequency, low power ultrasound (1 – 10 MHz). The range from 20 kHz to around 1 MHz is used in sonochemistry whereas frequencies far above 1 MHz are used as medical and diagnostic ultrasound.

Industrial grade ultrasonic nanomaterial dispersers are mainly used for large-scale industrial production. Industrial high-power ultrasonic sonochemical processing equipment, with high power, high efficiency, large radiation area, suitable for large-scale industrial production, with real-time monitoring of frequency power, adjustable power, overload alarm function, length of 930mm. Industrial grade Jinghao brand ultrasonic nano material disperser has 80%-90% energy conversion efficiency


Physical Effects

There are three different theories about cavitation – the hot-spot, the electrical and the plasma theory. The most popular one is the hot spot theory. Thus, it has been experimentally shown that the cavitational collapse creates drastic conditions inside the medium for an extremely short time: temperatures of 2000-5000 K and pressures up to 1800 atm inside the collapsing cavity. A remarkable event during the cavitation collapse is the emission light under certain conditions (Sonoluminescence). Furthermore, the collapse causes a couple of strong physical effects outside the bubble: shear forces, jets and shock waves. Thus, there are basically two groups of effects: radical and mechanical effects. These cavitation-induced effects can cause physical, chemical, and biological effects. Thus, ultrasound has been found applications in chemistry, materials and life sciences as well as medicine.


Chemical Effects

There is no doubt that the origin of sonochemical effects is cavitation. There are three possible reaction sides of a collapsing bubble: the cavity interior, the bubble vicinity and the bulk solution. Due to the extreme conditions inside the medium and other cavitation effects the following effects depending on the sonication conditions have been found:

Application: 

• Cell disrupter (extraction of plant substances, disinfecting, enzyme deactivation)

• Therapeutic ultrasound, i.e. induction of thermolysis in tissues (cancer treatment)

 Decrease of reaction time and/or increase of yield

• Use of less forcing conditions e.g. lower reaction temperature

• Possible switching of reaction pathway

• Use of less or avoidance of phase transfer catalysts

• Degassing forces reactions with gaseous products

• Use of crude or technical reagents

• Activation of metals and solids

• Reduction of any induction period

• Enhancement of the reactivity of reagents or catalysts

• Generation of useful reactive species







We need to customize according to your working conditions, liquid information, throughput, and spatial information....

So, before qutation, we may ask for many information about your application, like :

what's the liquid you dealing with?

what's the Temperature, pressure under work?

what's the capacity?

what's the inatll enviroment?

....

We have customized more than hundred ultrasonic liquid processing for different application.

Sonochemical reactions

Three classes of sonochemical reactions exist: homogeneous sonochemistry of liquids, heterogeneous sonochemistry of liquid-liquid or solid–liquid systems, and, overlapping with the aforementioned, sonocatalysis (the catalysis or increasing the rate of a chemical reaction with ultrasound). Sonoluminescence is a consequence of the same cavitation phenomena that is responsible for homogeneous sonochemistry. The chemical enhancement of reactions by ultrasound has been explored and has beneficial applications in mixed phase synthesis, materials chemistry, and biomedical uses. Because cavitation can only occur in liquids, chemical reactions are not seen in the ultrasonic irradiation of solids or solid–gas systems.

For example, in chemical kinetics, it has been observed that ultrasound can greatly enhance chemical reactivity in a number of systems by as much as a million-fold;[16] effectively acting to activate heterogeneous catalysts. In addition, in reactions at liquid-solid interfaces, ultrasound breaks up the solid pieces and exposes active clean surfaces through microjet pitting from cavitation near the surfaces and from fragmentation of solids by cavitation collapse nearby. This gives the solid reactant a larger surface area of active surfaces for the reaction to proceed over, increasing the observed rate of reaction. 

While the application of ultrasound often generates mixtures of products, a paper published in 2007 in the journal Nature described the use of ultrasound to selectively affect a certain cyclobutane ring-opening reaction. Atul Kumar has reported multicomponent reaction Hantzsch ester synthesis in Aqueous Micelles using ultrasound.

Some water pollutants, especially chlorinated organic compounds, can be destroyed sonochemically.

Sonochemistry can be performed by using a bath (usually used for ultrasonic cleaning) or with a high power probe, called an ultrasonic horn, which funnels and couples a piezoelectric element's energy int
