Description

Technical Field

[0001] This utility model relates to the field of water-reducing agent synthesis technology, and in particular to a catalyst addition device for water-reducing agent synthesis. Background Technology

[0002] Organic synthesis reactions are indispensable in the food industry, chemical smelting and other fields. The reaction conditions of organic synthesis reactions are complex. In order to increase the reaction rate, a certain amount of catalyst is added to many organic synthesis reactions. At present, the catalyst is added to the reaction equipment all at once, which can easily lead to excessive addition at one time, insufficient reaction of materials, or unstable reaction process. It may even lead to dangerous situations caused by excessive addition of catalyst.

[0003] Existing catalyst addition devices for organic synthesis raw materials cannot accurately add the appropriate amount of catalyst. Too little catalyst will not achieve the best catalytic effect, while too much catalyst will result in waste. Therefore, we propose a catalyst addition device for water-reducing agent synthesis.
