To observe the progress of chemical reactions or to produce new reactants.

At present, neither the gas-liquid reaction experimental device nor the liquid-liquid reaction experimental device has a reasonable structure. In the gas-liquid experiment, the gas reactant is poured into the container containing the liquid reactant, so that the gas only contacts with the surface of the liquid reactant; in the liquid-liquid experiment, pour the gas reactant into the container containing the liquid reactant Another liquid reactant, the poured liquid reactant has only partial contact with the liquid reactant in the container. Therefore, in the existing gas-liquid and liquid-liquid reaction experimental devices, the reactants cannot be fully mixed, resulting in insufficient reaction, which not only affects the experimental data, but also wastes reactant resources. Furthermore, due to the artificial addition of reactants, the feed rate is difficult to control, so that the reaction rate cannot be controlled, which is not conducive to experimental observation. In addition, if the properties of the reactants are unstable, especially the gas-liquid reaction requires strict conditions, artificial feeding is very likely to pose a safety hazard.
