Process for the production of 4-nitrotoluene-2-sulfonic acid Abstract of the Disclosure A process for the preparation of 4-nitrotoluene-2-sulfonic acid by sulfonating 4-nitrotoluene with oleum is described. The sulfonation is carried out continuously with 50-85 % oleum, while keeping the conversion of 4-nitrotoluene in the reaction mixture at ?90 % during the entire reaction course. |
