Anyone Know How To Turn 70% Alcohol Into 100%

Just out of curiosity ... why would you want to do this ??
Please answer if it's safe here. :0

I had a look here and from my limited comprehension of chemistry .... deduced that:
You would need special gear as at such purity, the substance would:

a) bevery volatile .... as it is reactive with lots of other chems. Will burn at 50/50 with water.
b) it would probably want to evap.
c) if one was to ingest it .... one would most likely die ... rather quickly ... you would go blind ... your liver would explode.

But that is just common sense ....No ??

This is a quick excerpt from wiki if you just want to have a quick glance

Ethanol, also called ethyl alcohol, pure alcohol, grain alcohol, or drinking alcohol, is a volatile, flammable, colorless liquid. It is a powerful psychoactive drug, best known as the type of alcohol found in alcoholic beverages and in modern thermometers. Ethanol is one of the oldest recreational drugs. In common usage, it is often referred to simply as alcohol or spirits.

Ethanol is a straight-chain alcohol, and its molecular formula is C2H5OH. Its empirical formula is C2H6O. An alternative notation is CH3–CH2–OH, which indicates that the carbon of a methyl group (CH3–) is attached to the carbon of a methylene group (–CH2–), which is attached to the oxygen of a hydroxyl group (–OH). It is a constitutional isomer of dimethyl ether. Ethanol is often abbreviated as EtOH, using the common organic chemistry notation of representing the ethyl group (C2H5) with Et.

The fermentation of sugar into ethanol is one of the earliest organic reactions employed by humanity. The intoxicating effects of ethanol consumption have been known since ancient times. In modern times, ethanol intended for industrial use is also produced from by-products of petroleum refining.[1]

Ethanol has widespread use as a solvent of substances intended for human contact or consumption, including scents, flavorings, colorings, and medicines. In chemistry, it is both an essential solvent and a feedstock for the synthesis of other products. It has a long history as a fuel for heat and light, and more recently as a fuel for internal combustion engines.

If I am wrong on this one please correct me as I would like to know any errors in my thinking .... also .... as it is my turn to be lazy to look it up....What is the difference bwn say
40 % proof and 40% pure. (as an example)

Have a great day !!

Sick Stoner you can distill alcohol (ethanol) to about 85% with a home made distiller, you might get it in the 90s with proper reflux still. Everclear is only 95%, a higher percentage may be extremely difficult outside of a lab.

Puffer "proof" means proof that the alcohol will light on fire - this takes at least 50% alcohol which is 100 proof - that the alcohol is not watered down by the press gang. 200 Proof is 100%.

French Press Double Boiler Reflux Extractor





100 Proof of Distilation


I took this picture, the flame is from the reflux distilled alcohol from my first run.

I started with 40% (80 proof) vodka and distilled it to remove the alcohol from the swill, before taking the resin out of solution. 1/2 teaspoon burned for a couple of minutes. I'll get a hydrometer and see how the percentage is changing with each distilation.

Here's a drop of clear alcohol dripping from the test tube cold finger in the french press distiller.



And 100 ml of clear alcohol in the colector, which I'm reusing on another extraction, and will continue reusing.

Reflux towers are relatively easy to make if you know how to sweat copper. My first one cost ~150 bucks to make since I had the 25k btu burner from an old water heater.

Home Distiller has some great info on how to do this effectively.

Thank you for your insight and da planz .... now I am going to have to make one ... cause I roll like dat ... and in this case with your pointers.
Thank you for teaching me something !!

Cheers

Sup sick.

I'll help you out with waaaay less hassle than a home made distillery. If its for cleaning a shroom box, the denaturing of rubbing alcohol won't hurt the mushrooms.

Rubbing alcohol + epsom salts. Stir in a cup of salts for every pint of rubbing alcohol, then remove the salt. Do that 3-5 times and the salt will have absorbed the excess leaving you with damn near 100%. If you're crazy about 100% absolute purity build a still. . . but thats crazy. Salt will put you in the high 90's without breaking a sweat.

How do you remove the salt? Doesn't it disolve in the alcohol? This would beat the hell out of paying $25.00/gallon for 99%.

I started to write a long post on this but its not really required is it? ;)

Salt and water will mix, salt and alcohol will not. I tried to dissolve 1/2 teaspoon of table salt in one oz of 100% alcohol that was purified by a molecular sieve (science nerd friends are fun). It would suspend briefly then become goo at the bottom. Little bit of stirring with water and most of the salt disappeared for good. The epsom salt absorbs water is large enough to be strained out, it basically dries out the alcohol.

Salting anything dries it out, the shit sucks up water. If you doubt me check out a chemistry site.

The more you know!



BECAUSE KNOWLEDGE IS POWER! :-P

Its one of the reasons you mix rubbing alcohol and epsom salts to clean your bong. The salt is an abrasive to grab res and improves the effectiveness of the alcohol.
