Nitration reaction system

The utility model relates to the technical field of chemical equipment, and particularly discloses a nitration reaction system which comprises an acid phase separator and a loop reactor. The loop reactor comprises a combination of at least one non-circulating reactor and a circulating pump, an outlet of the circulating pump is communicated with an inlet of the non-circulating reactor, and an inlet of the circulating pump is communicated with an outlet of the non-circulating reactor; or the loop reactor is a circulating reactor; the acid phase separator is suitable for separating an acid phase, and an inlet of the acid phase separator is communicated with a reaction liquid outlet of the last-stage loop reactor. The circulation reactor is adopted, continuous feeding, continuous reaction, continuous discharging and separation of an acid phase and an organic phase containing products can be achieved, full-automatic control can be achieved in the whole process, labor cost is reduced, personal safety is guaranteed,
