Abstract
A continuous photochemical reactor comprises a rotatable cylindrical reaction vessel provided at its one end with an inlet for reaction mixture and at the other end with an opening, a lid body for closing said opening of the reaction vessel and for discharging reaction products, a lamp mounted on the lid body and coaxially arranged in the reaction vessel, and a driving means for rotating the reaction vessel around its axis. The reaction vessel is provided at its inner wall with a spiral conveyer blade so that the inner edge of the blade is arranged close to the outer wall of the lamp. A reaction mixture is fed to the reactor through the driving shaft and irradiated by light such as ultraviolet light from the lamp while being conveyed by the spiral conveyer blade.
