Hydrogen halide is formed is continuously removed from the organic solvent, halogenated succinimide Rirenkarubon by a halogen element in a two-phase mixture consisting of water and organic solvents
A process for preparing halogenated rylenecarboximides of the general formula I in which the variables are each defined as follows: A, B together are an imide radical or, in the case that n is 1, A and B are also each Hal or one radical is Hal and the other radical is halogen; R, R are each independently hydrogen; optionally substituted alkyl, cycloalkyl, aryl or hetaryl; Hal is chlorine, bromine or iodine; n is 1, 2 or 3; x is from 2 to 8, by reacting a rylenecarboximide of the general formula II in which the A and B radicals together are an imide radical or, in the case that n is 1, are also each hydrogen with elemental halogen in the presence of an inert organic solvent S1, which comprises continuously withdrawing the hydrogen halide formed in the course of the reaction from the solvent S1.
