Here's something that you might want to add to your excellent video. When it comes time to remove the alcohol from the container. Simply freeze the whole thing. I checked and saltwater containing all the salt it will hold will not freeze until it reaches about 6 degrees F. Once that happens, just pour off any liquid and all you get is the alcohol. The isopropyl alcohol doesn't freeze till minus 128 degrees F. This is an old trick that folks used with hard cider. Put it out in the cold during winter and after it freezes, any liquid left will be serious drinkable alcohol... just give the remaining frozen apple juice to the kids.
I've never seen this method before, very interesting and easy. Keep in mind that isopropyl alcohol's ability as a disinfectant isnt best at higher concentrations. It's ability peaks around 76% I believe because water is important in the breakdown of microorganisms.
I went to Lowes and got gallon of denatured alcohol for $12. I cut it with 20% water and 1 squirt of liquid hand soap per pint. Works great and doesn't evap too soon.
Should work as a disinfectant, but you need to be careful with it on your skin depending on the denaturants used. Some brands may include methanol which is absorbed through the skin. Sadly the brand Menards had didn't show the entire contents, though I'm sure I could of looked up on on an MSDS sheet.
Yup DENATURED ALCOHOL is often 100% methyl alcohol/methylated spirits/methanol is some markets. I can't find any true denatured alcohol (ethanol made non drinkable by cuting it with toxic and bitter chemicals) in my area in canada in hardware stores other than ethanol fuel for alcohol stoves.
For those wondering, the concentration on the bottle is by weight. Alcohol being less dense than water should have a larger volume than the water in a new bottle assuming the claimed concentration is >30%. In an old bottle however alcohol will evaporate more quickly than the water so the concentration drops over time so you should really treat an old bottle as a solution of an unknown concentration and just take what you get.
Isopropyl alcohol and salt experiment. I performed this experiment with 70% Isopropyl and it produced a small amount of water per volume than your experiment using a 50% solution. Does the higher the alcohol percenctage produce less water when doing this experiment?
That's exactly right. Say you have two of the same sized bottles. One is 50% isopropyl alcohol and the other is 70%. Even though they're the same amount of liquid, the percentage is telling you how much of that liquid is isopropyl alcohol. Generally, the remaining liquid just seems to be water. So, obviously if you have a higher percentage of a liquid that's not water, you'll have less water in the mixture.
I haven't shopped for it lately, but I've got 90% alcohol I bought somewhere, probably a drug store. Should I assume there's a shortage of that stuff nowadays?
what's stopping the salting out from getting closer to 100% alcohol? I recently started resin 3D printing too, so I'm rotating at least two batches of alcohol, a clean one to wash the fresh prints, and a dirty one left alone of a day or two to allow resin to settle on the bottom, before I siphon out the cleaner alcohol (I decided to use one of those electric water pumps for the large water bottles - they're cheap and can pump alcohol out w/o disturbing the resin at the bottom). But I was looking for something cheap to displace the alcohol further, and water came to mind, but normally it's not good, because of the strong H-bonds it makes with the alcohol.
I'm no expert, but water and alcohol easily bond into one liquid because of how their atoms are structured. This makes it very hard to fully separate the two once they're combined. Using this "salting out" method doesn't fully separate the two liquids either. The top liquid is just mostly isopropyl alcohol, but still contains water, while the lower mixture is more water and salt, but still contains trace amounts of isopropyl. If you have a low concentration of isopropyl alcohol, like anything below 90%, I would assume you could do at least 2 or 3 things to improve the concentration. 1. You start off with a higher concentration of isopropyl. Preferably 91% or higher. After the first dehydration cycle and the water separates, freeze the mixture. Saltwater freezes at a much higher temperature than isopropyl alcohol, while the isopropyl freezes at such a low temperature that your freezer probably couldn't freeze it if you wanted it to. After the water freezes, simply pour the isopropyl into your desired container. 2. You could then try running your newly concentrated alcohol through another dehydration and freezing cycle to see if you can get any more water out of it. But, I suspect you might get so little water back during a second cycle, that you might need some sort of a sieve or strainer to filter any lose grains of salt and ice from the alcohol as you pour it out. Still might be worth trying. Also, you could certainly improve the storage method while the mixture separates. You should be able to put it into a sealed container so that the alcohol doesn't evaporate. You could also look into either purchasing, or building a homemade, vacuum chamber. I'm fairly certain I remember something about people separating water from alcohol in a vacuum chamber since they evaporate at different pressures. The vacuum chamber method could very well give you 100% isopropyl alcohol, or close to it, no matter what concentration you start with. They're also relatively cheap to build a homemade one.
@@tEzekielt , Thanks! The freezing is a good idea! And I'll investigate the one with vacuum chamber. I already saw a guy reach 100% alcohol using molecular sieves that only allow water molecules in.
Interesting, you found different results than I did when I googled it. The salt that I used in this video did dissolve without any problems until it reached saturation.
Obviously there are other ways to separate the fluids. Personally I'm not concerned about my dirty mouth, I'm more concerned about other peoples dirty mouths. ;)

You mentioned the printers. Have you ever used this method to wash and cure resin prints?

I figured that too, it is good to understand what is happening and the difference in percentages. Thank you, Nestea Plunge.
Ya learn something new every day
Great tip. Does that work on cheap vodka too? : ) Mahalo for sharing!
Wont' work, ethanol cannot be dried that way unfortunately.
No, but run the cheap vodka through a Brita filter 2-3 times and you'll get great vodka 😎
Love this channel sir..👍super helpful & entertaining👌
THANK YOU ❤
I haven't shopped for it lately, but I've got 90% alcohol I bought somewhere, probably a drug store. Should I assume there's a shortage of that stuff nowadays?
Also, what if I just went to the booze store and bought Everclear? Would that not do the trick?
At the time of the video, alcohol was hard to find. Everclear would work though!
Smart guy

Can we do this with ethanol?
Brilliant !
But what happens when you use iodized salt
Nice idea.
You can boil the salt water to reclaim the salt to use again
You can condense the steam to reclaim the water as well.
You can follow Ed's advice and basically go blind and most likely d|e. anyone who would drink this has his brains shoved tightly up his arse.
Just drink it
Clever stuff 👍👍
good info
iodized salt does not dissolve. Unless in extremely high temp.
When you get a chance Google this then come back and tell me what you found out.
@@1D10CRACY have in the past and takes 1200 degrees to actually melt it.
Have you tried it with non iodized salt?
Interesting, you found different results than I did when I googled it. The salt that I used in this video did dissolve without any problems until it reached saturation.
@@Suuegrl melting and dissolving are 2 different things
Can you take 91 and get it to 100?
100% isn’t possible 99% is the highest
HOW WOULD YOU KNOW THE ALCOHOL CONCENTRATION PERCENTAGE ,OR WHAT PERCENT OF ALCOHOL
YOU WOULD NEED TO USE AN ALCOHOMETER
Thanks 👍
If you want to desanitize something, you should cough on it
Use something OTHER than your dirty mouth to remove the solution
Obviously there are other ways to separate the fluids. Personally I'm not concerned about my dirty mouth, I'm more concerned about other peoples dirty mouths. ;)
