Continuous production process of nitrosoantipyrine

The continuous production process comprises a sulfuric acid storage tank, an antipyrine storage tank, a sulfuric acid delivery pump, a spiral feeder, a sodium nitrite storage tank, a sodium nitrite solution delivery pump, a batching kettle, a supergravity dynamic liquid membrane reactor, an antipyrine and sulfuric acid solution delivery pump, a sight glass and the nitrosoantipyrine storage tank. Sulfuric acid and antipyrine are prepared into a solution in a burdening kettle, and the solution and a sodium nitrite solution are simultaneously introduced into the supergravity dynamic liquid membrane reactor for reaction to obtain nitrosylantipyrine. According to the invention, continuous production of nitrosyl antipyrine can be realized, and the problems of poor product quality, large batch-to-batch difference, incapability of realizing continuity and low process efficiency in existing kettle type intermittent production are solved. 本发明公开了一种亚硝基安替比林的连续化生产工艺，包括硫酸储罐、安替比林储罐、硫酸输送泵、螺旋进料器、亚硝酸钠储罐、亚硝酸钠溶液输送泵、配料釜、超重力动态液膜反应器
