Oky Ive been messing as i normally do... So will 190% Proof alcohol be oky to use with dry ice.
Ive got my own 25 Ltr distiller and this is what we produced on the first test run, After 3 Distils we got it to 190%.
Next will be to get some equipment to get it all sorted and get some dry ice as well.
Ive stored away 5 Ltrs in None Leaching Ali bottles with safety valves for future use. The rest got watered down and handed out to mates at 100%.
Keep in mind 200 "Proof" is 100%
190 Proof is 95% Alcohol, This can be readily acquired in the form of Everclear as long as you are over the age of 21 in the good ole USA.
I imagine with some work you can distil 100%
Yeh we can but means another run all so in the UK we cannot buy this stuff and tbh i think its illegal how ever its not for drinking just for trying dry ice cooling. I think i posted here before i would like to try it out and this is my first attempt at doing it.
I might put that 5 Ltrs i have set aside though one more time see if we can hit 200% (100% real value). Im quite happy we got it this high on the first run TBH (in fact im buzzing). Mind you this stuff is bloody dangerous.
The only problem is its cost us £35.00 just to create 5 ltrs at 95% real wich is not that cheap. Mind you after drinking it as a tester t 5ml its a bit mental.
Can't get any of that in California :(Quote:

You will be fine using Everclear with DICE. It will/should not freeze solid
Wood alcohol (methanol)
freezes at -97.8° C (-144.0° F)
boils at 64.7° C (148.5°F)
Grain alcohol (ethanol)
freezes at -114.1° C (-173.4° F) -- Everclear Alcohol? Something 180+ Proof
boils at 78.5° C (173.3° F)
Liquors:
24 proof liquor freezes at -6.7°C (20°F)
64 proof liquor freezes at -23.33°C (-10°F)
84 proof liquor freezes at -34.44°C (-30°F)
Isopropyl Alcohol
90% isopropyl freezes around -90.0°C
Acetone is cheap easy to get and it's freezing point is -78c.
just don't spill any on the motherboardQuote:

As for getting it on the motherboard, acetone is very corrosive, but it's not difficult to get it in the pot instead of on the board. ;)
Acetone also has the best properties for dry ice
if i remember right the best transmission qualities
I always use 190 proof Everclear (95% ethyl alcohol + 5% water + 0% anything else) as my interface when doing dry ice. It works well. Note that there is a 151 proof version that is sold in some markets where the regular stuff is outlawed and it is best avoided. I've never been left with so much as slush. Any other brand of the same thing should work fine so long as it isn't flavored.
Some benefits of ethyl alcohol over others:
1) It's only nominally toxic...you can drink it in small amounts as humans have done for ages.
2) It's relatively inexpensive and readily available.
3) There are no fumes to speak of when cold and when warm the fumes don't smell as bad as ketone fumes do (acetone).
4) It won't dissolve plastic or epoxy (PCBs, mounting rings, foam insulation, etc).
Note that rubbing/isopropyl alcohol isn't the same thing. It will start to gel at DI temps. Methyl alcohol is best avoided as it's extremely toxic to humans. Denatured alcohol should also be avoided. It's typically isopropyl (gels/freezes) that has been methylated (toxic).
I would like to add that denatured alcohol (Klean Strip) works completely fine.Quote:

It is roughly 50% ethyl and methyl each, so yes it is extremely toxic to humans. Ketone is used in a small quantity. (~5%)
However it works well in the pot.
To be clear, "denatured" just means it has had something added to it to keep it from being consumed. It can be any type of alcohol. The stuff you're using sounds like the common solvent "MEK", not denatured alcohol. It's odd they'd sell it labeled as such. As for ketones, that's the class of chemical acetone is. If you buy a can of hardware store acetone, it's nearly 100% acetone and thus nearly 100% ketone.

ETC. this is the best bang for the buck. For 15 bux you will be allset for a session. your dice will be cashed before the vodka. 160 proof. always make sure you add more dice than vodka. You basically want a slushy. take a long knife or something rigid and always stir occasionally. what happens is the dice will freeze over your container and clog the holes on your container so you want to break up the ice on the boiling holes so the vodka can get to it. I average around -70c with this combo.

Can't you get this ?

I don't know how much it costs but less then 2€ for a 250ml bottle. It's 96% V/V ethanol ( there are some brands that go as far as 98% V/V ). You can get it from every supermarket, pharmacy, wtv store here in Portugal.
