Re: ACIDMELT/TRYP...R-12
I have find this process for substitute ammonia anhydrous .
I can it be valid to reduce ephedrine process ?
----------Formule-------------
-------------Formula--------------------
Blue ammonia can de made by mixing 2 parts ammonia nitrate (fertilizer), 1 part red devil lye (NaOH) and a little of pure salt (NaCl). take 2 dry tanks (5gl propane tanks) 1st tank is mixing tank. Put a 3/4 x 4 nipple on to top of mixing tank then 3/4 valve- 1" nipple- 1 3/4 tee- then screw 18" piece of pipe onto tee sticking straight up with screw on cap. Off of tee short nipple and 3/4 valve, pipe over from this valve to second tank.
take all dry mixtures from above and put into tank 1. Make sure both valves are OFF. Take cap off of 18" pipe, fill pipe with industrial strength ammonia. While tank 2 is totally submerged in ice open valve 1 and let liquid ammonia drop. let react for 15- 20 minutes. open valve 1 then 2, you will hear vapors go from tank 1 to tank 2. Do this step several times until it stops reacting. You should have pure blue ammonia
that will melt lithium strips when added. This ammonia will eat up the brass valves so try to use stainless steel valves if possible. You will need to replace the brass ones when you hear, or see it leaking. You will smell the vapors leaking from the valves when they need to be replaced. Does not yield a lot of liquid ammonia, but it does work if done right.

Re: ACIDMELT/TRYP...R-12
ok AM, just because you are willing to answer here is 25 yrs worth of knowledge(ha ha). 2400- 60's = 144g psedo, 36 - AA bunny strips, 4000 ml annie = 1 gal. to much some say but its worked for swims dreams. if 1 gal seems alot, think, complete li reduction(no unmelted pices) and just a little longer evap time. end results 90 - 105 g everytime. remmember you can not control ALL the conditions every time, so maybe more - maybe less return. that depends on many things, but always treat your dream like it is your newborn, lots of care and attention. the more you dream the same dream the easier it will be. !!!! !!!!!!

Where can you get annie from for $500? Do you have to have a special license?
