Removing the epoxy around a chip. If it is diluted, it will eat the chip also, against the belly feeling.

Cheers, Gerhard.

Stereo-typically Massachusetts is known for having stringent laws on paper but a somewhat more relaxed and lenient judicial system; Rhode Island's laws are more permissive but is known for having a very harsh judicial system. The judges and police don't get called out as often but when they do they're super-annoyed.

Over the years I've good luck removing epoxy and composite type material with NaOH

It is similar as e.g. absolute ethanol in many countries: you can get a licence for having and using it for approved use. The licencee is often required to be a registered company / organization.

You need to open a company that uses nitric acid in its processes. Then you are allowed to buy. And 3% HNO3 is just an example, the full list is here, appendix one:

"Seven restricted substances are listed in Annex I (on their own or in mixtures or substances including them). These substances cannot be made available to or introduced, possessed or used by members of the general public, unless a Member State decides to keep a licensing or a registration regime."

No, you can find a lot of suppliers and any concentration you might want. You are just not allowed to buy, and the seller is not permitted to sell, unless the buyer represents a certified company ? otherwise, two years of enhanced reflection independently for each of them.

Nitric acid can be used to nitrate toluene and glycerine, so possessing it immediately makes you a terrorist. Sulphuric acid can't do that, so it is perfectly legal. Want 98% or more? No problem, because it is damn impossible to convert H2SO4 into HNO3. Oh, wait...

Now it gets interesting. Why ethanol?

Best regards, Piotr

Finding a supplier is not a problem and the prices are very affordable. The tricky part is not going to jail.

It is up to the member states to define how it should be regulated. Next time you cross your eastern border with a bottle in your luggage, make sure it is sufficiently diluted, or you might stay a bit longer than you planned.

Best regards, Piotr

Same with, e.g. pepper spray for personal protection. Perfectly legal in Poland, illegal in the UK, Greece, Denmark, half-legal in Germany (can be used only against animals). I once took mine to London for a short business trip, because I forgot to take it out of my bag. I had thrown it away before I went to the airport on my return trip, as I am not particularly interested in obtaining a British residence, let alone in waiting for it in the Tower of London. :->

Best regards, Piotr

No wonder the UK droppped out of that EU s*it. Never had a problem buying any chemicals in the US. Some suppliers are real pretentious, but you can always just not use obnoxious companies. I was even told my address "looked commercial" at one place I straight up told I wasn't with a company. Unless it's a controller substance like drugs, or you're in trapped in california, nobody cares.

Yeah you know you live in a free country when you can buy any industrial solvent you like that 99% of the population wouldn't know what to do with but weed is illegal almost everywhere. /eyeroll

Don't know why so many Americans think they live in a "free country." There are police up your ass just about everywhere you go. There are so many some Americans seem to have confused freedom with trying to be friends with all policemen.

Police & cameras that should say

Welcome to the Nordic way of looking at booze!

Anything above vodka (about 40%) is considered a regulated substance. 'Absolute' in the previous post was not the Swedish trade mark, but a kind of ethanol destilled to higher concentration than the azeotrope with water (around 70%).

Which often (almost always) had a trace of benzene in it too since that was the classic method for breaking the azeotrope. These days they may well use something slightly more benign like xylene or toluene but not something you would ever want to drink even in trace amounts.

Methylated spirits in the UK usually contains purple dye, pyridine or other bittering agent like denatonium and enough methanol to ensure you go blind from drinking it.

Right now there is a lot of it (non-potable ethanol) being used by redundant gin makers to manufacture hand sanitiser gel. They have the alcohol handling kit and license but no market with pubs all shut.

To me, the term "absolute ethanol" means concentration level 100%. The only sane large-scale application of it that comes to my mind is its use as a benign solvent. Way too many percents for proper booze, however, one can rarely find a violet-nosed expert connoisseur with enough experience to attempt that feat. :->

It is legal in Poland; the 96% variant is mostly used by amateur tincture makers, which is quite a popular hobby in the older generation. It used to be sold in pharmacies as well, not sure how about now, probably it still is.

Best regards, Piotr

depends on what part of Nordic, the most well know Snaps here is 45% and I've seen plenty of 50% Gin and 80% Stroh Rum

The azeotrope is 95% ethanol or 190 proof. It's sold round here as Everclear, Graves, and Polmos "rectified spirit".

We made a bunch of hand sanitizer out of it last spring.

It's as cheap as drugstore rubbing alcohol, and much better for cleaning circuit boards. ;)

Drinking? Well, maybe in some strong-tasting fruit punch, but not otherwise.

Stroh rum--that brings back some memories. When I was 18 (1978) I went on a bicycle tour from Vienna to Paris. One night early in the trip we stayed at the Hotel Schafbergspitze, which was one of those seasonal mountaintop places they specialize in in Austria--complete with its own cog railway.

A bunch of us had bought small bottles of various kinds of schnapps, and proceeded to do shots. The 120 proof stuff wasn't too bad, but taking a shot of 160 proof Stroh was enough to knock your head back, for sure. That stuff was _rough_. (Fortunately there was beer for a chaser.)

Turned out to be a fairly early night. ;)

We once tried to get a federal booze tax exemption for pure ethanol to clean PCBs, but they were skeptical.

In the Tulane chem department, they had an IR absorption spectrometer. They only used it before parties, to make sure there was no benzine in the ethanol.
