Wow, SO3 is an amazing substance, I always wanted to make some and do some nitronium sulphate-based nitrations :D I don't have the equipment to do so, though.

It seems there isn't an appropriate thread for showing all kinds of weird stuff found online, but this is the closest one here because there are photos inside this link.

Adrian's Home Chemistry Lab

If this is one of you, guys, I'm sorry for my ignorance. It's just that I'm amazed by the awesomeness of this lab. Not only it looks like a 19th century lab where some guy discovered a chemical element, but it even has a freakin' organ inside to add some general spookiness. :o
The videos are really cool, do check it out.
One thing scares me a bit - I don't see a ventilation system and it seems like the lab is a neat place to slowly poison yourself as the years go by. :D

Also, I wouldn't keep a neat and expensive thing like an organ inside a lab where corrosive fumes linger around...

Hehe. I dissolved the nitronaphtalene in a bit of acetone and let it evaporate. The interesting thing is that only the bottom of the petri dish was covered with the liquid - there was just a few mililiters of it. And yet the solid somehow climbed the container's walls.

That's called an evaporative creep. Usual nuisance.

Two small bromine apoulles and a small flask with the rest of the bromine what I have used in a reaction.

Each ampoulle contains 25-30g of pure Br2, wouldn't be funny to break one :D




I have a blog where I post my pictures from my work: http://labphoto.tumblr.com/

Here is Sulfamic Acid after overheating and sudden change to this solid (amber like) state after cooling down in vacuum.

Bubbles of gas got trapped inside of it.

Weird.

It turns out that making NO2 is easy. I used a TV circuit high voltage line, a couple of canadian 25 cents (pure nickel). I also added a small cup of water to absorb the NO2 and make HNO3.

Evening all.
I'm new to the forums and figured I'd just introduce myself with a picture.

Italian might be familiar with this stuff based on his previous posts.

Iron Acac crystals. Also, I have Copper Acac but it's kinda boring to look at.

how to make this, what should I take out from tv?

by the way, which safety precautions you take with this?

thanks

Search for TV Flyback driver. It is the black transformer the red high voltage wire from the CRT comes from.

Its an easy project to re-write the primary to get some really high voltage. High voltage can easily break down insulators and kill you. A neon sign transformer would work too and is current limited.

The heat from the arc breaks down nitrogen and oxygen into NOx very inefficiently.

There are some ‘arc chemistry’ examples on this forum if I recall well and they don’t use high voltage sources, rather they use grid power (110 or 220 V AC) with a suitable reactance to limit current. See this old classic for an electric furnace:

http://www.sciencemadness.org/talk/viewthread.php?tid=2492&a...

and:

http://walkermetalsmith.com/reprints/Portable-Arc-Furnace.pd... (example of reactance near the end of the article)

A certain charm


These aren't necessarily "pretty" but I wanted to post them anyways. I always thought chemical containers from back in the day have a certain charm to them...
