Solvent question.
    #1158532 - 12/20/02 06:00 PM (13 years, 11 months ago)

Is this stuff pure? It appears to be only denatured alcohol. Ethanol and Methanol. What do you think?

$3 @ Walmart



its pretty hard to read but the important part says
'Contains Ethanol, Methanol'
it gives no other references to other additives.

It 'Thins shellac. Cleans glass and metal. Clean-burning fuel for marine stoves'

thanks

The same stuff over here (it's called methylated spirits) contains about 90% ethanol, 10% methanol plus pyridine (to make you barf) and blue dye

If your worried I suggest you get a bowl and fill it up with the alcohol and let it evaporate to see if there's any residue left.

i wouldnt use that as a solvent if you are planning on consuming the final product. denatured means that they intentionally poisened it so people dont drink it. so there would proly be some very bad residue

if it's denatured, it's not pure. combined with the fact that it's cheap, the question is, what isn't in it.

i would do what daussaulit suggested. however, i'd be surprised if there wasn't some unpleasant residue left behind after evaporating. out of curiousity, what's your plan?

Read the small print and you'll probably find a Benzene warning somewhere.NO HARDWARE STORE SOLVENTS ARE CLEAN ENOUGH TO INGEST IN ANY FORM!!!!!
Good Luck,WR :wink:

As a solvant, why not just use 99% Isopropyl alcohol?

In reply to:

If it's denatured it usually means that methanol(wood alcohol) is added, which makes it undrinkable, unless you like to be poisoned and want to be permanently blinded.

i'm not planning on drinking any of it. a solvent would evaporate.  It sounds as though there may still be some unpleasantries in this junk tho.  anyone have any experience with solvents.  I dont want to spend an arm and a leg for some pure ethanol or methanol but i'd rather be safe then sorry  :laugh:

yes, usualy. not always.
metyhanol isnt' the only adative used in denatured alcohol.

You going to try my idea? Just spend $3 for that can that you saw, pour into a bowl and let it evaporate? That's probably your best bet. I'm pretty sure no residue will be left.

I'll try this. tonight and get back to you.

EDIT:
put a small ammount of the alcohol in a half pint.
It seems completely clear. Strong ethyl alcohol smell.
Updates to come

Again I warn you against "harware store solvents" Industrial methanol(the denaturing agent) is contaminated with benzene and will leave it in your final product as an impurity even after evaporation.Please consider this as a source of clean EToH of 99+%.

First create a space (small room,big closet) and seal it.use a dehumidifier to lower the RH as much as possible and do this.

1)get some everclear(95% EToH)

2)get some calcium chloride(dri rite)

3)add 1cup dri rite to 1l everclear

4)shake and then let stand

5)filter through coffee filter

6)filter through charcoal

7)filter though coffee filter again

8)bottle and cap tightly until use

This will yeild 99+% EToH if performed quickly in a very low humidity. Cap the result tightly as alcohols are hygroscopic to a degree and if left open will reabsorb H2O from the air.

Methanol is the prefered extraction solvent but I have had good results with slightly acidified(a few mls of ascorbic acid solution @ 10g/L) EToH.My extracts do not store well for over a couple weeks but I know they are food grade and not contaminated with toxic metals or hydrocarbons as is EXTREMELY likely from OTC solvents.Only reagent or pharmaceutical grade solvents should be used if one cannot use food grade EToH.These grades of solvents while not impossible to obtain they are difficult and dangerous for the average layman to purchase via chem suppliers.I will probably catch flak for this but I've read (and done :crazy: yrs ago to get LSA) about using Lighter fluid and other stuff in A/B extractions,Butane honey oil,etc and the contamination in all of these solvents is usually benzene which is a severe carcinogenic.As well much industrial  MEoH is contaminated with organometalic compound formed in the synthesis. I hope this will be of help to you  :wink:  WR

Re: Solvent question. [Re: Cow Shit Collector]
    #1164911 - 12/23/02 01:19 PM (13 years, 11 months ago)

In responce to an email i sent to 'Klean Strip' about the purity of their denatured alcohol they sent me:

"There is also a very small amount of Methyl Isobutyl Ketone"



and here is a Fact Sheet on the chemical.

Very small residual left in the test 1/2 pint container. Its slightly cloudy and odorless. I would think this stuff would be ok. The effects of the keytone are not to bad from what i've seen. maybe its possible to heat it out?

any comments
