How do I go about using something like this (pic) to make anhydrous ethanol or methanol?

You need to add benzene to pull the water out and then distill it. Keep in mind that you have to keep this in a completely air-tight container where the distilled ethanol has no air/room in the container because it will pull all the moisture from the air.

So you'd need to buy Benzene + a bunch of glassware huh?

A lot of benzene.

You can literally just buy ethanol denatured with methanol.

Also. Why do you need anhydrous ethanol.

Fuck the whole benzene bullshit that's retarded. Listen. Epsom salt, magnesium sulfate. you get it at walmart. It's in its unhydrated form. You put it in azetrope ethanol in equal molar amount as the remaining volume of water in there and the crystals will turn into the hydrate form. You filter that shit out and youve got your 200 proof. The alcohol is so hydrophilic that it will take in water from the air, so when you store it, you want to keep some excess salt in the bottom and just filter it out when it's time to use it. Yer welcum

If you're going to use sieves (like something in your picture), it won't be too hard, if you have them sealed in their original container. Otherwise, they're probably already 'wet' and have to be heated to very high degrees to give up their moisture. Just take the dry sieves, and put them into 95% ethanol.

Depending on your tech level, you might want to set up a distillation apparatus and put some more sieves, or magnesium strips, or CaO or Whatever in the path of the vapor.

Some beverage distillers actually use dried plant material from the original grain in the distillation column to pick up water, and then mix it back into the mash.

Yeah I can't find a single image example online of the molecular sieves in use, nor any how-to guides.
So that's basically it though, just vaporize some ethanol/water and send it in the path of the sieves?
Or just mix the sieves in with it?

And yeah, I could try MgSO4 too.

Just fucking buy it. No don't do that with the sieves. If the sieves work, they work, if they don't, they don't.

You can use anhydrous copper sulfate (white) and it'll turn blue in the solution. Keep adding copper sulfate until no more turns blue.

Or you could just buy anhydrous ethanol which is often cheaper than anhydrous copper sulfate and molecular sieves.

magnesium sulfate won't take it all the way to 200 proof but it will get you slightly past azeotropic ethanol.

Sieves are easy to use; you don't even need to distill anything, and they can be regenerated by simply putting them in a pyrex flask (or improvised equivalent) and heating with a torch while shaking them up until no more condensation appears at the mouth of the container. They will absorb a little water while cooling but it's not much of a problem unless the humidity is super high or you need ABSOLUTELY dry ethanol. If in doubt stick a coffee filter filled with another drying agent (like mag sulf.) in the opening while it cools, so any air entering is relatively dry. Either way, the sieves will still make ethanol way drier than using MgSO4. They do take a while to work, but all you have to do is dry them out, dump them in, let it sit a few days, then filter off the sieves.
