swim agrees w/ geez, as usual, and would add that, when using fb precursor in a lwr, it may bee prudent to beegin on ice, and let things evolve very gradually, to avoid that sudden exothermia.
swim has always dreamt of tossing it all in cold; covering it once and only once. problems in the order of adding ingrediants have been about texture, more than anything else.
sometimes, one dreams of unmixed crud getting stuck on the sides of the flask beefore it's all mixed well, and staying there for 24 hours or more. which is worth avoiding, especially in nano rxns.
which leads me to this possibly stupid question, which may have been covered beefore, but i can't utfse, beecause of painfully slow connection and out-back phone service:
when doing a free-base rxn, might it bee good to add the freebase in a solution with an np? this would keep it as a liquid, hopefully, until after the exothermia of HI formation, so that it needn't suffer the added exothermia of the acid/base rxn until after the np had evaporated.
or maybee the np could remain in there all along without harming things? keeping it all more slippery?
thanks for feedback
