How Does Power Ultrasound Improve Chemical Reactors?

The integration of one or more ultrasonic probes (sonotrodes) allows to couple powerful ultrasound waves into the chemical reactor. Intense ultrasonication of liquids and slurries not only create strong turbulences due to acoustic vibration but is known for multiple effects, which are defined under the term “sonochemistry”.

What is Sonochemistry? How Does it Promote Reactions?

Hielscherning UIP1000hdT (1kVt) ultratovush apparatida ultratovushli kavitatsiyaHigh-intensity ultrasound / high-power ultrasound is applied to chemical systems in order to initiate and/or promote reactions, improve conversion rate and yields or to switch reaction pathways. The physical phenomenon responsible for sonochemical effects is acoustic cavitation. When high-intensity ultrasound waves are coupled into a liquid medium, the waves travel through the liquid creating alternating low pressure (rarefaction) and high pressure (compression) cycles. During the low pressure / rarefaction, minute vacuum bubbles arise in the liquid, which grow over several pressure cycles until the vacuum bubble reaches a point where it cannot absorb any further energy. At the point of maximum bubble growth, the bubble implodes violently during a high pressure cycle. During the implosive bubble collapse, the phenomenon of cavitation can be observed. Ultrasonic cavitation creates so called “hot spots,” which are characterized by extreme conditions such as temperature of up to ∼5000 K with very high heating/cooling rates of > 1000 K s-1, pressures of up to ∼1000 bar as well as respective temperature and pressure differentials. The liquid or slurry is heavily agitated by liquid jets and shear forces.

Video shows ultrasonic cavitation in water using an ultrasonic homogenizer (UP400S, Hielscher). When sonicating liquids at high intensities, the sound waves that propagate into the liquid media result in alternating high-pressure (compression) and low-pressure (rarefaction) cycles, with rates depending on the frequency. During the low-pressure cycle, high-intensity ultrasonic waves create small vacuum bubbles or voids in the liquid. When the bubbles attain a volume at which they can no longer absorb energy, they collapse violently during a high-pressure cycle. This phenomenon is termed cavitation.

The chemical effects (e.g., the formation of radical species, flexing of molecules etc.) and physical / physico-mechanical effects of sonochemistry are successfully applied to numerous chemical reactions such as organic catalysis, organocatalytic reactions, phase transfer reactions, nanozarrachalar sintezi, precipitation / crystallization, sol-gel reactions, Suzuki coupling, Diels-Alder reactions, Mannich reactions, Michael addition, Wurtz-type coupling and many others. Sonochemically promoted reactions often show a significantly increased conversion rate, higher yields, accelerated reaction, more complete reaction, can be used with milder solvents under ambient conditions, create less unwanted by-products and contribute due to its high efficiency to green chemistry.

Ultrasound-Driven Chemical Batch Reactors

Pastdan yuqoriga nanopartikullar sintezi, katalitik reaktsiyalar va boshqa ko'plab sonokimyoviy ilovalar uchun ultratovushli aralashtirilgan reaktor.The integration of ultrasonicators into open or closed batch reactors is a commonly applied technique to accelerate reactions in laboratories, pilot plants and production facilities. Depending on the vessel size, geometry and the chemical reaction system, one or multiple sonotrodes can be integrated into the batch reactor. Ultrasonication is also often used to improve continuously stirred reactors (CSTR).

Ultrasonic Semi-Batch Reactors: Of course, sonication can be also integrated into semi-batch reactors. For semi-batch systems, one chemical reactant is loaded into the reactor, whilst a second chemical is added at a continuous flow rate (for instance, at a slow feed to prevent side reactions) getting combined in the ultrasonic hot spot. Alternatively, a product of a chemical reaction, which results from the reaction in the reactor is continuously removed, e.g., synthesized precipitates or crystals, or an intermediate of end product that can be removed due to phase separation.

Ultrasonically-Agitated Chemical Flow-through Reactor

In a flow-through reactor, also known as flow cell or inline reactor, the reactants are feed through one or multiple feeding ports into the reaction chamber, where the chemical reaction happens. After a certain retention time that is needed for a specific reaction to occur, the medium is continuously discharged from he reactor. Ultrasonic flow cells and inline reactors allow for an uninterrupted production of product, which is only dependent on the continuous supply of the reagents.

Sonication and sonochemical reactions can be run in batch reactors as well as in continuous flow cell reactors.

The picture shows the ultrasonicator UIP1000hdT with batch reactor (left) and with flow cell reactor for inline processing (right).

The beauty of sonochemically driven reactions is the efficiency that can be reliably achieved via process optimization. Optimum ultrasonic amplitude, ultrasound power input, temperature and pressure can be determined for each particular reaction. This allows to find the ideal sonication parameters so that optimum reaction results and efficiency are achieved.

Haroratni nazorat qilish

All our digital ultrasonicators are equipped with a pluggable temperature sensor for continuous temperature monitoring, which can be inserted into the liquid for constant measuring of the bulk temperature. Sophisticated software allows the setting of a temperature range. When the temperature limit is exceeded, the ultrasonicator automatically pauses until the temperature in the liquid has lowered to a certain set point and starts automatically sonicating again. All temperature measurements as well as other important ultrasonic process data are automatically recorded on a built-in SD card and can be revised easily for process control.
Sonochemical reactors from Hielscher are available with cooling jackets. Additionally, heat exchangers and chiller units can be connected to ensure the desired process temperature.
