【摘要】 以聚苯乙烯和水为介质，在五个几何相似的模拟硝化反应器中，对流体的停留时间分布（ＲＴＤ）规律及该系统的放大规律进行了初步研究，确定了固液相硝化反应器的最佳中试规模为０．０４０ｍ３，给出了相应的经验式，为固液相硝化反应器的放大提供了理论和实验依据更多还原

【Abstract】 Five geometrically similar nitration reactors filled with polystyrene and water as mediums were used to simulate the rules of residence time distribution(RTD)of the fluid and that of reactor scale-up. The experimental results show that the optimum pilot volume of solid-liquid phase nitration reactor is 0.040 m3. The relevant empirical formula of scale-up is obtained thereof, which can be used as theoretical and experimental reference for the further investigation.更多还原
