How is recrystallization done in industry?
The solvent can be considered a good full added, can be divided into, the reaction kettle has the corresponding solvent tank, the liquid level on the metering tank gauge can be calculated by adding the amount of solvent, at the same time there are some flowmeter through the flowmeter reaction can also add the solvent volume measurement.
Preferably in the production of the current to do a test before the material, simulation under tongnem (station contact TA), in fact, the best way is to go to the workshop in person, consult the workshop master, to ensure that you harvest a lot.
Before the best feeding, according to the volume of the kettle and the loading factor, the material is well calculated and put into use. Of course, fear of solvent multi throw, before debugging can be appropriate less points, not enough to fill, with a pump, the loss is very small..
Solvent, I usually calculate all, add in, because at high temperatures, vacuum pumping will have great losses. Of course, it can be artificially supplemented, but it is more troublesome. Haha415 (station contact TA), in addition to the mirror + lamp can be observed, you can drop observation.
