Abstract (en)
[origin: WO2004052860A1] The inventive method consists in adding an acid which removes hydrogen halide, especially HCI contained in a reaction mixture and makes it possible to carry out photochemical halogenation, especially chlorination of organic components by substituting hydrogen-chlorine, although initial components, target components or eventually present amines form, together with free hydrogen halide, for example HCI additive products which could form precipitate without acidification
