Specification
Bronopol (CAS NO.52-51-7) is a white crystalline powder,can be used as analytical reagent for the synthesis of drugs and raw materials.it derived from the reaction of succinic acid and ammonia.
The main process is the acid and water during tung ammonia reaction to produce succinimide. Succinic acid can also be put through dropping ammonia to dissolve and react, then heated to 102 ℃ steam to water, further vacuum distillation, when heated to 180 ℃, started to collect fraction succinimide , that was finished.
