Mn(III)catalyst prep and subsequent rxn?
Hi,
after some reading I decided to prepare the Mn(III)(0AC)*2H2O
catalyst from Mn(II)(OAc)*4H2O
and the procedure seems just to filter off the Mn, then, it´s dried, re-used with acetic acid as a solvent in further reactions, so why borther
cleaning the flask and using new acetic acid, when essentially the reaction conditions remain the same with leaving it as is?
thanks, nightflight
edit: this maybe should be moved to reagents acquisition.
Title edit by Chemoleo:
It is Mn, not Mg.

So you're getting Mn precipitate after using the catalyst? Best practise is to separate the metal and wash it before using it again. Otherwise the
next reaction will contain rubbish from the last one, or maybe even the formation of the acetate salt would be hindered.

Yes, you´re right, cleaning and reaction work-up is my weakness, but then again, I´m lazy, at least for the first time until something failed.

Bold mine. Its just a guess but maybe it has to do with the drying? If you have acetic anhydride or
ketene then this step might be obsolete.
But its really just a guess....
