Abstract: The synthesis of succinimide from succinic acid and ammonia in the presence of phosphorous acid was studied. When the reactant mol ratio was in 1∶1.1; the initial reaction temperature was 70 °C and then kept at 120 °C for 1h; the cyclization reaction temperature was 195 °C and this temperature was maintained for 5h, the yield of succinimide was good. This method has been adopted for industried production at a level of 200 kg.
