在有机物合成实验中，常会遇到伴有毒性气体产生，实验都要采取一级成多级吸收装置。但难免有部分气体向外扩散。利用抽吸引流吸收的原理，设计了反应吸收装置，使产生的有害气体，定向流在吸收瓶而被相应的吸收液所吸收，效果很好。此装置具有结构简单、取材方便，操作容易等特点。 In organic synthesis experiments, often accompanied by toxic gas production, experiments have to take a multi-stage absorption device. But it is inevitable that some gases will spread outwards. By using the principle of suction and drainage absorption, a reaction absorbing device is designed so that the harmful gas and the directional flow absorbed in the absorption bottle are absorbed by the corresponding absorption liquid, and the effect is very good. The device has the advantages of simple structure, easy drawing, easy operation and the like.
