Versuchsvorschrift
To isolate the 4-nitrotoluene-2-sulfonic acid, the sulfonation mixture is adjusted to a sulfuric acid concentration of 70% and diluted with mother liquor from a previous crystallization to a 4-nitrotoluene-2-sulfonic acid concentration of 35%. After centrifuging at room temperature, 936 g of 100% 4-nitrotoluene-2-sulfonic acid (98.5% of theory) are obtained from 600.0 g of 4-nitrotoluene.
