Mystery...funnel?

Here's an interesting picture of something-or-other in a Buchner funnel:



But what is it? Anyone wanna take a guess? (Come on, guys. This one should be easy.)

I'll post the answer tomorrow or Saturday...

functionalized (well, we hope so) carbon nanotubes

activated carbon

Nope! (Not exciting enough to merit a picture.) Try again :)

Zinc powder?

magnesium dioxide?

i mean manganese dioxide, whoops.

Ψ*Ψ said...

Contains no zinc or magnesium.

Shot in the dark....is it a tetraacetylated b-glycoside? before recrystallization from EtOH? Twice?

20 questions?
Does it contain Palladium?

You have clearly synthesised concrete. Build something before it hardens in the funnel.

Looks like carbon nanotubes to me -but I doubt you have apparatus to make them. So my guess is something highly condensed polyaromatic (and poorly soluble) such as pentacene.

Hexaphenylbenzene?

Excimer said...

haha, it's not hexaphenylbenzene. Hexaphenylbenzene's a pretty boring white solid.

Milkshake wins! Functionalized carbon nanotubes.
...I am a little unsettled by his guesses, though, since they sound like things I might actually be working on. Are you stalking me, milkshake?

milkshake said...

No stalking - but you work on a material science project, and it is probably something carbon based, so the choices are limited

One thing - I am amazed how much of that stuff you are actualy making. I have seen carbon nanotubes only on pictures but usualy in tiny quantities, never in multigram amount.

Russ said...

Huh. I made hexaphenylbenzene (many years ago though, as an undergrad), and I thought I remembered it being a dark purple (almost black) solid. Am I maybe thinking of the precursor - tetraphenylcyclopentadienone?

Excimer said...

Yes you are, Russ. Check out an earlier post I did on the reaction.

Ψ*Ψ said...

It's actually not my project but a labmate's. (I'm glad my stuff is a little more soluble than that.) Most of what the group does is on the scale of a gram or so.

Chemgeek said...

That's a lot of nanotubes! How many total meters of tube are we talking?

Mitch said...

What temperature do your nanotubes decompose?

Ψ*Ψ said...

I don't know...they're not mine!

Mitch said...

I know, but I was looking for a general answer. Nothing specific

Lakshmi said...

Wow, that was a terrific yield of CNTs. I hope they were pure.. you (or whoever made it) would make a fortune.
