A method for carrying out a reaction between at least two reactants in a liquid reaction solution in at least one reaction zone so as to produce a reaction product includes carrying out a reaction continuously in a reaction flow for the at least one reaction zone in an extension of the at least one reaction zone as far as at least one reaction product outlet, introducing each of the at least two reactants over the extension of the at least one reaction zone via inlets in which the reaction flow is introduced, and removing the reaction product via the at least one reaction product outlet.
