The steps to build a dripping and steaming reaction device are as follows:
1. It mainly involves a utility model patented technology, which includes a reaction kettle, a dripping tank, and a condensate collection Tanks and condenser parts. First, you need a reactor, which is the main equipment for chemical reactions. Then there is the dripping tank, the bottom end of which is welded with a dripping tube, and the bottom end of the dripping tube is plugged into the inside of the reaction kettle.
2. In order to control the flow rate, a flow regulating valve is threaded on the outside of the dripping tube. In addition, several dripping tubes are welded to the end of the dripping tube away from the dripping tank. There are several dripping holes on the outer wall of the dripping tube. This can make the dripping liquid more evenly dispersed in the reaction kettle and avoid local concentration. Too high to reduce the occurrence of side reactions.
3. Next is the condensate collection tank and condenser. The condenser is located outside the reactor. Circulation pipes are welded on the top outer wall and one side outer wall of the condenser, and the circulation pipes are inserted inside the reactor. A collection tube is welded to the bottom of the condenser, and the end of the collection tube away from the condenser is welded to the top outer wall of the condensate collection tank.
4. The main function of these two parts is to cool and collect gaseous substances. The above components are combined to form a dripping steaming reaction device. Through such a design, the reaction can be made more uniform and stable, and the quality and yield of the output materials can be improved.
Precautions when building the device are as follows:
1. Keep the device clean. Before installation, make sure that all equipment is clean and free of impurities to avoid affecting the reaction effect or causing side reactions. Control the dripping speed. In order to prevent more reactants from being evaporated and lost, the reaction should be distilled while adding dropwise. If the reaction is difficult to occur, a device with dripping and refluxing can also be used.
2. Pay attention to the order of operations. For example, when the side tube is closed, first add the solution and remove the air, then seal it, open the side tube to balance the upper and lower air pressure, and then start dripping the material. Choose the appropriate solvent. The choice of solvent will directly affect the progress of the reaction and the quality of the product, so the appropriate solvent should be selected according to the needs of the reaction.
