Everclear is 95% ethanol and is sold in most states in the U.S.

I think the best option for someone who wants to produce constantly on a daily basis is to recuperate his solvents and invest in a Rotovap apparatus.
Do you mean by boiling your ether extracts while re-condensing the boiled vapors into a glass collection container. When i did this we used a vacuum pump to lower the atmospheric pressure to make the ether boil faster in the reactor and at a lower temperature, making it safer because it boils further away from its flash point. It was very time consuming, but we recycled i would say almost 70% of the ether back to be reused over and over again. Making it less expensive and less suspicious then purchasing more petroleum ether.
EDIT> I am about to do a THC extract with my buddy. He has obtained (i believe its called) protuelene sulfonic acid, and has a TEK that is supposed to result in 90% THC. He says it is less time consuming but similar to the isomerisation TEK we tried last time.
I imagine that psilocybin/psilocin extracts may be done in a similar fashion, but i have not read this book all the way through yet, or compared the differences and similarities between mushrooms and marijuana, and what chemicals are soluble with protuelene sulfonic acid.

The pear-shaped distilling flask which is spinned around its axis by the motor provides a very high surface area, so large amounts of solvent can be removed in a very short amount of time.
These thing go 1000-1500$ on lab auction site, but these tend to be generally overpriced. I've seen second hand units go for 100 euros in Europe a couple of years ago, they came from a company's overstock.
Distilling ether using only vacuum goes fast, but you'll need a strong and steady cooling. Dry ice would probably be best?
Regarding the CBD/THC isomerization using para-toluenesulfonic acid (= p-tosic acid), I remember seeing the paper.
p-tosic acid is very soluble in water and soluble in alcohol and ether. You'll have to perform the isomerization in alcohol, problem is separating the p-tosic acid from the product. I would propose evaporating 3/4 the amount of alcohol, flood with water and extract with ether or any other organic solvent.
The other method I remember was using HCl as the proton source. The yield were lower, but the workup is easier as it is volatile.

Thank you very much for the input. I will soon be performing my extraction. I know little of this process, but you just gave me a little better insight on the steps involved. I will also email your recommendations to my teacher to make sure we are going about it in the most safe and efficient way possible.

there are more nasty things in over the countor methelated spirits than just eg benzine and naftol try distilling it first if you have the glassware or just use isopropale alcole 5 quid a bottel in your cemmist say you nead it for cleaning computers and stress that it must be resedue free

The only non-volitile compnent should be petroleum oil, and that should only be in the crappy stuff, also easy to detect. Most denatured alcolhol in the US is just plain 90% ethanol and 10% methanol.

For the most part, you can get everclear at most military bases, even in places where it is illegal to buy it at regular liquor stores. So find a friend who is a military brat, then find a base with a decent "Class 6" (military designation for liquor store)

IF not that, go to your nearest chemical/scientific supply and get some ethanol or methanol, there is numerous legitimate uses for it, and if you know them, perhaps even preform thees legitimate experiments then it makes it easier to obtain with less questions asked.
I have heard that 195 proof everclear was even better to use then 100% methanol or ethanol because psilocybin is somewhat soluble by water and supposedly it helps to some degree to use an aqueous solvent.
Then again i also heard that 100% ethanol is created in a sealed environment because it absorbs water or moisture from the air to stabilize. I have been told it stabilizes at about 95% anyways. My friend says that if you open a full bottle of 100% ethanol and leave it out on the counter it will over flow from the water absorbed from the air.

It has been reported in the literature that 70% ethanol (140 proof) is the optimal mixture for extraction. Try some Bacardi 151. It should be great for extraction and flaming shots!
Anyways, let's let this thread die or lock it. There are already other extraction threads going with better info. The title pisses me off every time I see it.
