Liquid-liquid reactors find applications in various chemical processes, including liquid-liquid extraction, organic reactions, emulsion polymerization, and biodiesel production. Their ability to create a large interfacial area between immiscible liquids makes them ideal for processes that involve phase transfer.
Liquid-Liquid Extraction
In liquid-liquid extraction, the reactors are used to separate components from a liquid mixture by selectively transferring one or multiple solutes from one liquid phase to another, typically in solvent extraction processes.
Organic Reactions
For organic reactions, liquid-liquid reactors offer a unique platform for carrying out reactions between immiscible organic phases, enabling efficient mixing and reaction at the interface.
Emulsion Polymerization
Emulsion polymerization processes rely on liquid-liquid reactors to create stable emulsions, promoting the polymerization of monomers within the dispersed phase.
