It is well-known that nitration of dinitrotoluene (DNT) proceeds quite slowly. Unsatisfactory structure of nitrator could cause an incomplete nitration in the nitrator, and nitration continues in the separator. This, in turn, increases the temperature difference between nitrator and separator. It was found that the nitration degree of DNT in nitrator could be estimated by this temperature difference. We investigated the relationship between the nitrator`s structure and the above temperature difference, and based on the research results obtained we could make nitration complete in nitrator, improve the quality of trinitrotoluene (TNT), lower the consumption of raw materials, especially sulfuric acid, and increase the safety of production.
