Just a kind of renewable energy, unlike concentrated acids and alkalis, it does not produce waste that needs to be treated afterwards. It is safe to handle and generally allows for "mild" reaction conditions and lower energy consumption. As a powerful chemical reagent, light is the energy it can provide. It is different from violently heating a molecule to make it react. A single light energy that absorbs a photon can trigger a reaction. Sometimes, the light-driven chemistry of molecules can be very different from what happens when heated, opening up many exciting new reaction possibilities. Technologies such as photochemistry may completely change the method of synthesis technology. As a "clean, trace-free reagent", different light wavelengths can be used as the driving force for chemical reactions. Continuous stream photochemistry, that is, light irradiation, helps to shorten the reaction time, improve the mass transfer characteristics, the scalability is more direct, and the product can be harvested economically and efficiently.
Continuous flow reactors are an excellent way to produce high-volume chemicals, especially for special types of reactions, such as reactions that need to be triggered by light (called photochemical reactions). The continuous flow chemical microchannel reactor can achieve excellent heat transfer, low solvent waste, shorter reaction time, safer reagent processing environment and considerable yield of required products. This "enable technology" has broad application prospects in the synthesis and preparation of various toxic reagents and the advantages of different combination technologies (such as microwave assisted heating, electrochemical flow cell, LED light source).
Through careful synthesis process optimization and optimization and the combination of suitable chemical reactors, scientists can achieve several extraordinary goals for the target reaction: eliminating the need for organic solvents, recycling acidic reagents to reduce waste and improve safety, while achieving process enhancement .
Combining photochemistry with continuous flow conditions can significantly improve the efficiency of other photochemical methods such as photoredox catalysis. Continuous flow photochemistry can improve the efficiency of chemical synthesis, and it can also carry out reactions that would otherwise be impossible.
