Once again greetings everybody !!Love

I was experimenting with some extractions lately , but since my chemistry knowledge is very limited , i have some kindergarten questions about couple of methods .

Here it goes . I prepaired a bottle of some Acetone a couple of months ago , witch still has Magnesium Sulfate in it . Actually i was hoping to keep it that way because of ease of use , and anytime when i need some Anhydrous Acetone , i just could filter it and be sure that my Acetone has no water in it . All that because in place i live , air humidity is quite high all the time , and im a little paranoid about filtering all the Acetone at once , in another bottle. I believe that some humidity will get in it sooner or later.

What do you think guys , does after two months my Acetone witch still has Magnesium Sulfate in it , is still good to use ? Or does it go bad and my idea about keeping it that way was not good ..

Thank you in advance guysThumbs up

Best regards

Thumbs up should be nice and dry! You should be able to decant most of it without pouring out any of the magnesium sulfate particles.

This probably goes without saying, but the magnesium sulfate you added was anhydrous, dried in the oven?

This is how I would do it:

- Weight 200g magnesium sulfate (Epson salts)
- Place it on an baking dish covered with Aluminum foil
- Heat it at 200 C for 2 hours
- Collect the anhydrous magnesium sulfate
- Store it in an air tight container for future use

- Fill a 500ml bottle with the solvent to be dehydrated (Acetone)
- Add 25g of anhydrous magnesium sulfate
- Shake and let settle for a day prior use
- Always keep the magnesium sulfate in the bottle
- For usage extract anhydrous Acetone from above with a pipette

- The magnesium sulfate should hold 2x its weight in water
- 25 g anhydrous magnesium sulfate holds 50 g water
- 50 g water is > 10% volume of 500ml Acetone
- When you get below 100ml, discard the Acetone

You could try to re-use the left over Acetone:
- Add it to 25g anhydrous magnesium sulfate and wait a day
- Decant the Acetone away from the the magnesium sulfate
- Add the Acetone with new Acetone (500ml total) to new magnesium sulfate (25g)

You can re-use the magnesium sulfate:
- re-heat in the oven for 2 hrs at 200 C

Good luck!
