All known sulfonating agents are suitable for the process according to the invention. These are, for example, sulfuric acid, oleum, chlorosulfonic acid or chlorosulfonic acid-ether adducts, amidosulfonic acid, sulfur trioxide in undiluted form or diluted with nitrogen or air, sulfur trioxide-ether adducts or sulfur trioxide-nitrogen base adducts. Preferably, chlorosulfonic acid, sulfur trioxide in undiluted form or diluted with nitrogen or air or sulfur trioxide-nitrogen base adducts are employed. Sulfur trioxide-nitrogen base adducts are particularly preferred. These sulfur trioxide-nitrogen base adducts are commercially available or can be prepared by simple mixing together of the components. It may be advantageous to carry out the sulfonations with chlorosulfonic acid or chlorosulfonic acid-ether adducts, amidosulfonic acid, sulfur trioxide in undiluted form or diluted with nitrogen or air or sulfur trioxide-ether adducts in the presence of nitrogen bases. |
