Abstract: A method for coupling one or more different diazo components with resorcinol on an industrial scale is characterised in that the coupling pH of the initial resorcinol charge is adjusted and stabilised with the aid of a buffer system prior to the reaction and is kept at a constant value during the coupling reaction by means of a flow rate ratio control system for the streams of the diazo components and of the base.
