Methyl alcohol purification from fuel lube

math - 10-4-2012 at 05:33

Hello,

what would be the simplest/cheapest method to get klotz lube (0.5%) dissolved in otherwise pure 99.5% methanol?

Is distillation the only way or could one collect condensation vapors?

Thank you

The liquid's boiling point is probably a long way from room temp, since the flash point is 520 F. So with proper ventilation (you don't want to go blind from exposure to too much methanol vapour, so I would consider either doing this outside or in a fumehood), you might be able to boil all the methanol away on a water bath, and leave most of the lube oil (or whatever it is) behind.

For a test, try an eyedropper and a test tube. 1 drop of the lube (~1/20 ml) with 10 ml of methanol. See if it dissolves. The web page says that it "blends with" methanol as a fuel, so it may just go into solution directly.

I cannot understand your question. Are you wanting to get methanol from a mix? Or trying to dissolve this lube in MeOH?

I am sending this to Beginnings on the grounds that the question does not clearly indicate what the poster wants to do.

I'd want to get the methanol in pure form, without the lube or anything else in there.

Thank you

Why don't you buy some fondue fuel. Distill it and measure the vapor temperature to make sure you are getting pure methanol. I tried it once on a cheap brand and as far as I can tell, it is quite pure, maybe 99%.

You can buy methanol off the internet relatively easily, you can also get it from auto shops as way to remove water from fuel (HEET) or for racing fuel.
