This is probably a dumb question, but I can't find an answer

Whilst there are some thermometers that use air pressure, it's quite likely that yours is not going to be affected.
I doubt you'll even be able to create a vacuum strong enough to cause a problematic change in an oven anyway.

>>9052898
use a rotovap?

I dont think it should reflect the reduced pressure if it is completely housed in glass/plastic, airtight.

>>9052913
I asked around and it doesn't use air pressure, thanks for the reply.

>>9052918
I already used a rotovap, didn't quite get it all. The solvent is ethyl acetate, still showed up on NMR after rotovap

>>9052947
i would just use the rotovap longer, it should be able to remove it all given enough time. what's the product, can you say?

>>9052947
Do a vacuum destillation and a glass filter?

uh oh

>>9052953
Its already been on the rotovap for quite a long time, maybe if I can't get it out in the oven I'll let it go for a week or so. It is a dimeric ester, I can't be more specific than that

Dilute your compound with DCM, then evaporate on the rotovap. Repeat several times. Lots of compounds retain DCM much less tenaciously than EA.

If you're feeling cheeky you can do the same thing but with chloroform, then it doesn't matter if there's solvent in your sample, assuming chloroform is also your NMR solvent.

>>9052976
could you just remove the ethyl acetate signal from the NMR reading, citing it was non-evaporated solvent and thus could be discarded?

he clearly works for a lab, often times you cannot say your specific compounds, especially in organic synthesis labs. And you sure as shit cannot reveal your synthesis route.

>>9052999

What, because by telling us his intermediate diester compound we're going to be able to deduce what he's working on, figure out his target molecule, and quickly file a patent on the same compound to steal his employer's IP?

>>9053009
that's what his lab is afraid of, yes.

I appreciate the thoughts, but I really just needed to know how the thermometer would work under reduced pressure. I shouldn't have a problem removing the solvent
