摘要： Dinitrotoluene (DNT) is produced by the adiabatic nitration of toluene with nitric acid at a temperature of from about 60 to about 200° C. and at a molar ratio of toluene to nitric acid of from about 1:1.5 to about 1:3.0. The reaction mixture thus-obtained is concentrated to a water content of up to 30% by weight. The dinitrotoluene which is present in the reaction mixture is at least partially (if not completely) removed from the reaction mixture either before or after concentration of the reaction mixture. The DNT which is still present in the vapor generated during the concentration of the reaction mixture is kept liquid by the addition of a solvent to the vapors generated during concentration of the reaction mixture. The solvent added to vapor, together with any DNT present in the vapor is recovered. This solvent/DNT mixture may be recycled directly to the reaction vessel. The solvent/DNT mixture may also be separated. The separated solvent may be recycled to the solvent addition step. The separated DNT may be combined with the recovered DNT product or it may be recycled to the nitration reaction mixture.
摘要翻译：二硝基甲苯（DNT）通过甲苯与硝酸在约60至约200℃的温度和甲苯与硝酸的摩尔比为约1:1.5至约1:3.0的绝热硝化来制备。将由此获得的反应混合物浓缩至至多30重量％的含水量。存在于反应混合物中的二硝基甲苯在反应混合物浓缩之前或之后至少部分（如果不是完全）从反应混合物中除去。仍然存在于反应混合物浓缩期间产生的蒸汽中的DNT通过向反应混合物浓缩期间产生的蒸气中加入溶剂而保持液体。加入到蒸气中的溶剂与蒸气中存在的任何DNT一起被回收。该溶剂/ DNT混合物可以直接再循环到反应容器中。溶剂/ DNT混合物也可以分离。分离的溶剂可以再循环到溶剂添加步骤中。分离的DNT可以与回收的DNT产物组合，或者可以将其再循环到硝化反应混合物中。

摘要： Dinitrotoluene is produced by nitrating toluene with nitrating acid under adiabatic conditions in a manner such that some mononitrotoluene is present in reaction mixture. The nitration reaction mixture is then treated to remove at least 5% by weight of water before the reaction mixture is separated into an acid phase and an organic phase. The product dinitrotoluene is recovered from the organic phase. The acid phase may be recycled after nitric acid has been added to replace that which was used in the nitration reaction.
