Production method | It is obtained by the reaction of succinic acid and ammonia. Add succinic acid and water to the reaction pot, and the ammonia reaction can produce succinimide. You can also put succinic acid into the reaction pot, add ammonia water dropwise, and stir to dissolve and react, heat to 102 ℃ to evaporate the water, and then carry out reduced pressure distillation. When the temperature rises to 180 ℃, start to collect succinimide fraction to obtain the finished product. |
