Abstract

Способ получения п-нитротолуол-о-сульфокислоты сульфированием п-нитротолуола серным ангидридом в растворе жидкого сернистого ангидрида при температуре от -10 до +5C, отпаркой растворенного в реакционной массе сернистого ангидрида, гидролизом образующихся ангидридов п-нитротолуол-о-сульфокислоты и удалением непрореагировавшего п-нитротолуола, отличающийся тем, что, с целью упрощения процесса и повышения качества целевого продукта, гидролиз и удаление проводят одновременно путем обработки острым паром.The method for producing p-nitrotoluene-o-sulfonic acid by sulfonating p-nitrotoluene with sulfuric anhydride in a solution of liquid sulfuric anhydride at a temperature of from -10 to + 5C P-nitrotoluene, characterized in that, in order to simplify the process and improve the quality of the target product, hydrolysis and removal are carried out simultaneously by treatment with live steam.
