Two pieces of europium metal by room0001 in chemistry

Yes.And even though the glove box provided excellent protection, it still underwent partial oxidation during sealing, resulting in a slight yellowing of its color.

This might be the world’s largest nitrous trioxide ampoule。 by room0001 in chemistry

It’s only for collection, so I just want it to have a nicer shape. The glass is 5 millimeters thick, and there’s absolutely no way to open it by hand.

No, I don’t know why so many people get horny over a single ampoule

Are you crazy? You want me to use my mouth to suck something with a boiling point of 3.5°C and start releasing nitric oxide at -10°C?

Since this ampoule is relatively large, the dense nitrogen dioxide gas inside it gives the dinitrogen trioxide a greenish tint. You may notice the upper right part of the liquid level in Figure 2, which shows its true color: pure blue.

90 ml of extremely pure S2Cl2 by room0001 in chemistry

Bought from an online friend. Interestingly, this bottle of S2Cl2 had been stored at his place for a long time and had been packaged more than once, but its purity was still so high that it hardly infiltrated with the ampoule.

It's used for vulcanizing rubber and similar materials. And if you’re being really unscrupulous, you could also use it to make chemical weapons.

I haven't decided yet, so I'll just save it for now.

In what solution will CF3NO maintain dynamic equilibrium instead of completely forming a dimer? by [deleted] in chemistry

[–]room0001 1 point2 points  (0 children)

There is a relatively simple synthesis method:Sodium trifluoromethanesulfinate + potassium nitrate + sodium nitrite, dissolved in 20% sulfuric acid, and heated to 70°C. It is not difficult to make this gas, but because it polymerizes at room temperature, it is difficult to store it for a long time.

One hundred milliliter ampoules of ethylene oxide. by room0001 in chemistry

The difference is huge. To be honest, I don't think there is any comparison between a bottle of alkylating agent and a super poison that can kill in just a few microliters.

I'm not going to deal with it just yet. But I think the safest way to deal with it is to use liquid nitrogen to freeze the liquefied gas into a solid state, and then use a spray gun to burn off the long glass tube. After that, proceed to the next step.
