摘　　要：苯胺与浓硫酸通过磺化反应来制备对氨基苯磺酸是有机化学实验教学中一个常见的反应。该实验常在烧瓶中进行高温反应制备。本文试管反应对微型反应进行了改进,优化了微型反应装置,增加了反应操控性和实验效果。The preparation of sulfanilic acid from aniline with concentrated sulfuric acid by the sulfonation is a classic method in experimental organic chemistry reaction.The experiment is often prepared by high temperature reaction in flask.In this paper,an improved microreaction was presented as a tube reaction,and the microreaction device was optimized to increase the controllability and the effect of this reaction.
