The present invention relates to a process for producing monodisperse anion-exchanger gels with high stability, purity and coarse particle size greater than 800 &#x3bc;m starting from a monodisperse bead polymer with a swelling index of from 2.5 to 7.5 and more than one subsequent feed procedure without any separation between the polymerization steps and then modifying to give the anion exchanger.

Process for producing coarse-particle anion-exchanger gels

Sodium salts of aromatic sulphinic acids containing nitro groups are obtained in particularly pure form and good yield by introducing the corresponding sulphonyl chlorides into an aqueous alkali metal sulphite solution which is at a temperature of -10.degree. to 45.degree. C. and has a pH of 6 to 10, then cooling the suspension to -10.degree. to 0.degree. C., then metering in sodium hydroxide solution in such a way that the temperature does not exceed 0.degree. C. throughout the reaction, and then raising the temperature, maintaining stirring and simultaneously keeping the pH at 8 to 9 by the addition of sodium hydroxide solution.
