The resultant bromomethyl benzenes are often toxic and lachrymatory, and careful handling to avoid exposure is needed. Using the E-Series and UV-150 photochemical reactor it has been possible to carry out a range of photochemical brominations without needing to handle bromine, beyond making a stock solution. Improved reaction rates
Batch reactors have limited application for large-scale photochemical synthesis as most of the photochemistry occurs within a short radius of the lamp. To alleviate the limitation of scale associated with batch photochemistry our group has designed, constructed and implements a practical flow reactor for continuous organic photochemistry.
Tapered sides assure that the effective area of a 450w or 550w photochemical lamp can be entirely submersed into the liquid, contrary to traditional round bottom reaction flasks. Net result is approximately a 20% savings in reaction time. An additional advantage of this design is in the initial mixing of reactants.
In the design of the microreactor, we have considered the following requirements for accommodating photochemical reactions: (1) the cover of the device must be transparent to the incident light; (2) the reactor must have a large surface area to receive maximum amount of light possible; and (3) the device must minimize crystallization and clogging.
