Hey guys,
I have a synth coming up (currently waiting for the main reagent) and the synth calls for both a water bath and rotovap.
So to put my situation into perspective it’s important to say that I am learning chemistry as a hobby and I do not make things for people other than myself!
Okay so firstly with the water bath, is it to remove solvents or to keep the rxn going at a very specific temp? Or both? Or neither?
Secondly, it says to put the RM into a rotovap and strip it of the solvent - now, being a hobbyist chemist, I obviously do not have a rotovap - and it would take A LOT for me to obtain one.
I can understand why it would be incredibly useful, however, I was curious if I can just strip it of solvent under vacuum so as not to harm the valuable, yet relatively fragile compound I just created.
I understand it’s not a set and forget way of doing it, it’s just annoying that I’ll have to keep an eye on it.
Can someone take the time to explain? I’m sorry if these are really basic questions and no one takes me seriously, given how I am learning on my own and am operating on a VERY limited budget!
Oh also, can someone recommend a fairly decent rotary vein vacuum pump that is worth buying to run reactions? I’m in the UK but the way we all buy everything from China anyway kind of means suggestions can be made. I bought one before, however, didn’t realise it was a silly non oil one and can’t be left on for long and so it’s being used as my pump for filtration instead of being used for RXN’s.
I know I am asking a lot with this post but really any help would be GREATLY appreciated!
Regards
RR
