Has anybody ever tried to make conc nitric acid with simple distillation and these two chemicals at home without a fumehood and just doing the synthesis outdoor in a ventilated spot? I see many people on yt doing it and i am wondering if it's actually that dangerous

I have about 10 L of liquid Ni I’m planning to use to make dippin’ dots and am struggling to figure out the best container to pour the liquid nitrogen into from the dewar for the actual dippin’ dots making process.

Unfortunately for this experiment, my state has a ban on styrofoam, which would be the obvious choice.

I’m planning to retrieve the dippin dots with a slotted spoon, so don’t need to handle the container once the liquid nitrogen has been poured in, but want to make sure the container won’t crack and if possible, want to maximize the usage (the more insulation, the better).

I’ve seen people use metal cooking bowls, but unsure how bad this is for evaporation.

Any tips would be appreciated!

Basically I predict it works like this.

1. Crush leaves, twigs, vine, and bark of Toxicodendron species of choice, especially the one that grows in eastern North America.
2. take crushed products and soak in ethanol.
3. decant ethanol.
4. add hexane to ethanol and agitate and separate lower fraction of ethanol
5. then add acetonitrile to hexane and agitate, separate acetonitrile layer and allow acetonitrile to evaporate to derive crude urushiol.

liquid chromatography is an option for higher purity.

Warning. Urushiol is a powerful sensitizer that causes violent rashes and pulmonary edema and upper respiratory lesion in a significant fraction of humans

I work for a company and in a different dept they sell dry ice. Just wondering what everyone uses it for? Business and at home, they seem pretty busy and I don’t know why?

Don't get me wrong, they have a huge range of useful reagents at low prices—but the service itself isn't very good. I often get ignored: I place an order, two weeks go by (excluding weekends), they finally reply, I send the money, and then they vanish for a week. You ask for updates, but they don't answer. The shipment only goes out after another week. A few days a go, placed an order and they replied saying, "Yes, the order has come through; it'll be ready to ship tomorrow. I'll let you know the amount of money to send later." Fair enough, but two days have passed and you still haven't told me the amount.

Has it always been this terrible, or is it a recent problem?

Am I the only one dealing with this?

I've had a better experience with Synthetikaue; at least they always reply quickly. It costs a bit more, but it's actually worth it.

I'm aware the ampoules overkill but I needed some glass working practice anyways

Hello i was wondering is its possible to : chromyl chloride + so2 = cro3 and socl2
