Abstract
A process for producing dinitrile comprises supplying a Corganic 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 from 50 to 200° C. to convert at least a portion of the Corganic compound to dinitrile and water and produce a reaction effluent. At least part of the reaction effluent is supplied to a separation system to separate at least dinitrile and unreacted ammonia from the reaction effluent and additional water is supplied to a portion of the reaction effluent prior to or during separation of unreacted ammonia from the reaction effluent.
