Hi everybody,

This is my first post here, and first of all i'd like to say that my english often is nearest to be a s#*$ than a lenguage but, instead of use an on line translator, i`ll talk in the best way I can for myself to keep my authenticity. [If anybody has read this post, surely at this point will be thinking "This guy is an asshold..."]

So, in this my first post, I would like to ask you a practice question: which do you think is the best and straightforward way to add a solid reactant (which can`t be dissolved) to a reaction mixture in a two or three neck round bottom flask and under inert atmosphere.

I used to do it reducing the inert gas flow, removing the shortest time possible one of the septums and adding the solid from a vial through one of the necks to the flask.

What do you thing? Any way less troblesome to do it?

Thank to all,

Could you add the reaction mixture to the reactant? Ie. You have the solid reagent under inert atmosphere and then you add the liquid reaction mixture to the solid reactant using syringe

That's not the case. I mean when the addition of the solid reactant is a second step in the synthesis, and must be added once the reaction is running in the flask.

If you maintain a gentle positive stream of inert gas, you can open the vessel and add solids with minimal introduction of air and without making a mess.

Thanks a lot. Goodness what you say is what I was doing.
