Methanol dehydration
Thread Content
Dear brothers: I am currently using methanol as the extraction solvent, and the concentration of methanol recovered is only about 80%. I want to increase it to 90%. Is there any good way, such as dehydration? What dehydrating agent should be added, such as distillation, and what equipment should be used? Is distillation a big investment? Can I directly add a large amount of calcium oxide for dehydration?
Distillation is sufficient, and a steam-jacketed reactor, condenser, receiving kettle, etc. is sufficient. If that doesn't work, you can also dilute it with methanol with a high content.
Do you need to vacuum? If you don't vacuum, it won't be concentrated at all. If you vacuum, will the content be reached? Can an alcohol meter roughly measure the content? Thank you.

Industrial equipment can use distillation, but yours seems to be an experiment. I don’t know if there is any distillation experimental device. If it doesn’t work, let’s try a simple distillation.
Pervaporation inorganic membrane technology can also be used, which has a high recovery rate, low energy consumption, high purity, and saves space. It is fully automatic.
