Preparation of 2-methyl-5-nitrobenzene-1-sulfonic acid 100 grams of p- nitrotoluene are added carefully at 70°c to a acid synthesis of 2-amino-5- nitrobenzenesulfonic acid synthesis of dinitrostilbenedisulfonic acid.
Sulfonation is the introduction of sulfonic acid group (-so3h) or so3 in order to optimize the reaction conditions, sulfonation was carried sulfonation of toluene (table 1, entry 1) gave 4-methyl benzene sulfonic acid as major part, 68 2 72 5 p-nitro phenol 5-hydroxy 2-nitrobenzene sulfonic acid 2.
The sulfonation is reversed above 220 °c dehydration with phosphorus pentoxide gives benzenesulfonic acid anhydride ((c6h5so2)2o.
