isopropyl alcohol filter

Soluble in water... so anyway you can mix it with water to lose the oil and then separate it from the water after?

[superduperwesman]

... but getting it out of the water would prob involve heat too ahah

Solvent it is ahah

[superduperwesman]

In soluble is salt solutions? So what would happen if you mixed it with water and then added salt ahah. The salt just wouldn't dissolve or it would dissolve and separate the alcohol?

So far we have add water, add salt... and it still prob won't work ahah

[sphelps]

So you want me to add water to the alcohol? I'm not sure that will work, sounds like a headache.

You have to find something that takes oil out and leaves the alcohol. Or vice versa.
Not enough of a chemist to suggest any chemical.
But then again, thats why you are asking.
Maybe find a chemists forum.

The company I work for produces chemicals that do that very thing, but the cost of them is far greater then IPA. IPA is a commodity chemical, anything designed to seperate oil and IPA is likely to be a specialty chemical and therefore that much more expensive. Your likely better just changing out your IPA when it gets to dirty. If your worried about the environmental aspect ( thank you for being so ) most disposal companies have outlets for this type of material, they will most likely resell it to a company that will consume it in process. I dispose of 1,000's of kg's of material a year and very little of it goes to incineration or down hole, I venture to say less then 1%.

If I had the isopropanol to dispose of, I would research a little more and maybe burn it in my car. I know you can add 10% methanol with your gasoline.
