Photochemical Flow Reactor

Amar Equipments Pvt. Ltd. are largest manufacturer of MetalFlow Reactors in India. With Knowledge of more than 4 yrs infield of Flow Chemistry and based on research and developmentof various reactions; we at Amar, have combined the advantagesof continuous flow processing with the added benefits ofultraviolet light to enable photochemical reactions and aconsistent distribution of UV light to ensure

  • Higher productivity for photochemical reactions
  • Better performance
  • Homogenous absorption of light through the depth of the reaction channel
  • Higher yields

One of the key issues of scaling-up organic photochemistry in animmersion-well (batch) reactor is that light penetration to thesurrounding solution is limited by the high absorption of thesubstrate and falls off rapidly with distance from the lamp.Essentially the reaction solution nearest the lamp screens the bulkof the reaction solution from UV. This effect is also amplified if thereaction solution is concentrated. When the scale of the reaction isincreased with the same lamp it becomes increasingly moredifficult to drive the reaction to completion. Attempts to do sooften result in over-irradiation of the product and formation of sideproducts and photopolymers.
This is where flow photochemistry becomes a very attractiveproposition, as in principle it can overcome all the key problems ofbatch photochemistry.
