 N-Chlorosuccinimide (CAS NO.128-09-6) is a white crystal, soluble in water and alcohols, it can be used as pharmaceutical intermediates, organic synthesis chlorinating agent, it can also be used to prepare rubber additives, synthesis as chlorinating agent, antibiotic drugs intermediates.

 Production method is through the ammoniated acid chloride derived. Through dropping ammonia,react with succinic acid , stirring heated at 102°C steam to get rid of water. Vacuum distillation, collecting 180°C after the distillate to get succinimide. Molten succinimide increased to acetic acid aqueous solution, stirring cooled to 0-5°C, dropping sodium hypochlorite, control reaction in the 8°C below (otherwise there is risk of explosion). To clarify the reaction solution that is reached when the end point, centrifugation, filter cake and washing to neutral, drying, drying to get.
