What does charging a reagent mean in organic synthesis?
« on: March 30, 2014, 04:35:04 AM »
I'm reading an experimental procedure I would like to try out soon and the first step says in a round bottom flask equipt with a magnetic stirrer a reagent was charged and taken up in DCM. What does the charged part mean??

Not sure but it might mean positive pressure on a septa to transfer via cannula

Could you give a bit more detail on the reaction, reagents etc

It simply means that a reagent was added to a RBF and then DCM was added to dissolve it.

Thanks Disco, we lear more and more each day.

Must be an old paper which you are working from.

I think "charging" is still in common use. It often appears in OPRD papers and patents.

It's super common in industry. Our operators will never "add" anything, they always "charge" stuff.

Or rather, if it's a catalyst or flakes or some such they use "add", but anything pumped, pushed or sucked in via a pipe they will say "charge". Ah well, it's never a "pipe" but a "line". :)

In my experimental write-ups we frequently use "charge" in this context. For no particular reason other than convention.

I must have read that phrase hundreds of times and written it into numerous SOP's for manufacturing, not sure why the mental block this morning  :-*
