Why remove mgso4 when it need not be.
« on: May 11, 2003, 09:05:00 AM »
I was pondering this and will try it soon.
What is the purpose for filtering out mgso4 out of np layers before gassing.
I'm a stingy person when it comes to fear of losing goods during filtering the mgso4 from the np layer and rinsing it with more np.

I'm proposing this method and logically within my own mind it seems sound.
Put mgso4 in to np layer to dry.  put in freezer for 15 mins. 

Then gas the np layer.
afterwards filter crystals + mgso4.
Splash a bit of ice cold acetone to dry quickly.
Then redissolve in min alcohol then filter.
Pour a bit of hot alcohol through filter to get reaminin goods then seran wrap.
(dual solvent clean)

The epsom salt does not dissolve by alcohol or is affected by HCl gas
I believe this method would work and would love to give it a try.  The epsoms do not soak up crystals or soak up np layer.  Even if crystals are in its small crevices that's what the hot alcohol is for for rexin. 

Before I do, perhapse I'm overlooking something from a chemist background, so if any thoughts or reason why it wouldn't work please let me know. 

If this method worked, which i don't see why it wouldnt from logic point of view, then it could be adapted to other various gassing situations ie. mdma. dmt.  etc. etc list goes on.

but this is just stupid.

if you really care about lost product, then wash your drying
agent with pre-dried solvent: turn off vacuum, add dry solvent,
mix, turn on vacuum. (or similar, you will figure it out)

After laying out the steps, it seems to me that you save yourself a step of filtering the mgso4 before gassing. 
Since most people recrystallize, the mgso4 will be just viltered out in the process during dual solvent clean.
