The present invention provides a process for producing dinitrile, the process comprising supplying a C6 organic compound, an oxidizing agent, ammonia, and a diluent to a reaction zone to produce a reaction mixture, and contacting the reaction mixture in the reaction zone with a heterogeneous catalyst at a temperature of 50 DEG C to 200 DEG C to convert at least a portion of the C6 organic compound to dinitrile and water and produce a reaction effluent. The method further includes supplying at least a portion of the reaction effluent to a separation system to separate at least dinitrile and unreacted ammonia from the reaction effluent, and supplying additional water to a portion of the reaction effluent prior to or during separation of unreacted ammonia from the reaction effluent. 本发明提供了一种用于生产二腈的方法，该方法包括将C6有机化合物、氧化剂、氨和稀释剂供应至反应区以产生反应混合物，以及使所述反应混合物在所述反应区中与非均相催化剂在50℃至200℃的温度下接触以使所述C6有机化合物的至少一部分转化为二腈和水并产生反应流出物。该方法还包括将所述反应流出物的至少一部分供应至分离系统以从所述反应流出物中分离至少二腈和未反应的氨，并且在从反应流出物中分离未反应的氨之前或期间将附加的水供应至所述反应流出物的一部分。
