실험 절차

In this procedure, the reaction mixture is obtained as a black, tarry suspension towards the end of the addition of sulphur trioxide and, after hydrolysis of the p-nitrotoluene-2-sulphonic acid anhydride with water, an aqueous solution of p-nitrotoluene-2-sulphonic acid is formed from the suspension, and this is treated with active charcoal, before or after separating off water-insoluble by-products, in order to separate off dissolved, coloured compounds and dissolved, unreacted p-nitrotoluene.
