I guess my body is my temple, but this stuff is significantly cheaper than purified stuff

In reply to:

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





This is a very volitile solvent and would not leave a residue in pure form.

In reply to:

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?




you can try but if any residue is left I would find another solvent.What is the can made of? do you know why they make stills out of copper for alcohol? Alcohol stored in steel becomes toxic wth organometalic compounds(probably what you have in the bottom of the flask) GOOD LUCK you will need it if you are willing to use something which leaves an obvious residue.............WR

i have no idea what the evaporation temp of Methyl isobutyl Ketone is it but you might be able to get much of it out through distilation. if it evaporates at a lower temp than ethanol, it will end up in the heads, if it evaporates at a higher temp, it'll be in the tails. this will not, by any means, get all impurities out, or even all of the targe impurity, but if you know the evaporation point of your target, you can get most[/] of it out. as long as you have a little confidence and common sense, this distilation could be done with a simple water cooled, glassware, pot-type still. just don't under any circumstances use aluminum or any chromed metal, as you will end up with a host of new impurities in the solvent. also, you would have to be verry careful exercising such a proceedure indoors.

200 proof ethanol would be my choice [lab work is nice, sometimes :smile:  ] but one thing that would concern me if using mixed volatiles----What are the possibilities that some of these compounds could form less-volatile intermediaries when mixed with organic material? 
I can't think of any particular reactions off-hand, but it would be akin to treating things with bleach.  It's not really the bleach itself that would concern me, but rather the chlorinated organics, dioxins, that result from mixing the two. 
O-chem was awhile ago, any feasable reactions between ketones/aldehydes/etc. and organic material that would form more stable [potentially] nasty compounds? 

Compounds that could remain in crystallized form?    Just a thought.

I would DEFINATELY be concerned about reactions with the MIBK especially if heat is used to drive off the solvent.I really don't understand why anyone would use a questionable solvent when food grade EToH is available.If you ARE determined to use this cheap stuff at least pass it through activated charcoal to clean it up a bit more.If the MIBK is in small enough concentrations this will help remove some of it.When reducing the final product, after no smell remains allow it to stand for several hrs more to assure ALL volitiles are removed.If you are using this I have to assume you are not capable of distilling a more pure product but would encourage you to learn.Poisoning yourself slowly by playing Dr Jekyll is rediculous when better options are available.Again Good Luck........ :smirk: WR

yeah i think this shits out of the question. It just seemed a very cheap alternative to an otherwise expensive endevour. Anyone know of a good online store or location to obtain food grade pure solvents like denatured alcohol or ethyl alcohol? in the 99-100% range?
average prices per L?

there's no such thing as food grade denatured alcohol. ideally, you want chem grade solvents. unfortunately these are next to impossible to get for cheap.
you can distill ethanol to a good purity, then use something like epsom salts to get out almost all the the remaining water (though you'll realy never get it all).
if you have a good use for solvents, odds are such an undertaking isn't out of your scope.

whats your thaughts on using "cellulose thiners".

here the info on it:-

http://www.birdbrand.co.uk/msds/Cellulose%20Thinners.pdf

is it a viable and safe solvent to use for the extraction of LSA?

Looks like a real bastard mix of nasty solvents.  What in the hell would make you think using it would be a good idea?

It is a bit of a mix, but it evaporates extremely cleanly.

I was thinking about using it, but then i looked at the info for it.
I thought id ask your opinions on it anyway.

It's a bastard mix of eight different solvents.  Dealing with just one is already enough of a problem, so I don't think a crazy mix like this is a good idea.
