lactone purification

[wimpy]

Hey! Really thanks a lot - that's kind of light at the end of the tunnel
But do i get this right? As far as i understand one would not be able to get pure Nitrite out of this, or ... ?
So this leads to the question: would a smaller amount of NaCL affect the reaction?
Anyway, thanks a lot, swim will try as soon as possible!

You have very good prospects for purifying the nitrite - for each iteration of a fractional crystallization procedure using the bare minimum of water needed to dissolve the nitrite (but not more than that as to avoid dissolving too much NaCl) you will remove 75%+ of whatever amount of NaCl you still have left in your salt mixture. If I have calculated it all correctly you will have enriched the nitrite content by three orders of magnitude in five recrystallizations (or less!). If you start out with a NaCl:NaNO₂ ratio of 100:1 you will soon have changed that to 1:10...
100:1 ? 25:1 ? 6:1 ? 3:2 ? 4:10 ? 1:10

i really want to try this synth but i dont have a disstilation unit or the money to buy one. Could i use a retort instead of the "normal" flask/condenser method? they are a good deal cheaper.
