Experienced sodium carb washers...

[Psyren]

I just started messing around with sc washes. I have 2 one gallon jugs each with 450grams mimosa/3375ml NaOH water.
I combined the first pulls into one jar then combined 400ml of water and a pinch of sc in another jar then mixed jars together.
The first pull worked great, separated quickly, forgot to do a water wash and went straight to the freezer. White crystals precep just fine.

My next couple pulls have been creating massive amounts of foam and emulsions. ( have not been shaking to hard)
Sometimes it separates but the solvent has extremely milky/thick clouds. What's is this? I've grown mushrooms and it looks like mycelium growing in a liquid culture.
And one of my dried first pulls has a fishey smell as opposed to the new sneaker smell?? This is all obviously because of the sc but why?

Anyone have any knowledge you can send my way?

I would always take all the solvent pulls together in a sep funnel and QUICKLY run 3 x 30ml of water+sc. The quicker the better. I never once had a problem like you described. I would do 1 pinch per 30ml water. Separation was instant.

Fishy smell indicates base contamination I think...

 

[Psyren]

Can you define base contam?

Well I am not a chemist, but I have noticed that the basic solution [mimosa and lye] smells much more fishy than a little bit of sc in water. I have never noticed a smell at all from sc solution ever...but that's just me.

Make sure that between your quick washes, you have washed whatever you are using as a vessel to make the separations. You don't want the lye residue that you are trying to clean to just hang out on the glass and get picked up again by your washes.

Thanks for the help. Ill start using less water.

This technique can be used on Freebase DMT that has been acquired by either A/B, STB or a freebasing of DMT salts such as DMT fumarates.

1. Add drop wise to DMT Naphtha at room temperature, agitating until all DMT is dissolved. This may take some work at room temp, so a kitchen knife may help to stir/break up the DMT, then decant away from any remaining undissolved impurity's. Depending on how dirty the product was initially, some visually detectable impurity's may remain undissolved. These impurity's depend on the starting material, in the case of DMT yielded from FASW this may be excess fumaric acid (just one example). This is your Non Polar Phase.

2. Roughly measure the volume of DMT solution prepared in Step 1... and quadruple it. This is the volume of water you will add a pinch of sodium carbonate to. Literally a pinch. For a gram of DMT this pinch will be small. For 10 grams it might be a little bigger... it really doesn't take much. This is your Aqueous basic phase.

3. Mix the DMT solution (Non Polar Phase) with the Sodium Carbonate solution (Aqueous Basic Phase) with vigor for 3.333 seconds and firmly place upon the table, watch the two layers become visible and separate them mechanically as fast as possible using whatever baster/glass syringe/decanting technique you have mastered in the DMT extraction earlier. Separating these layers (technically phases) quickly is the key here other wise you will experience loss of DMT into the basic aqueous phase.

4. Taking the DMT solvent solution and evaporate it to a volume of 50% or less (till it go's milky when blown upon... this is to make it saturated so that the DMT can precipitate out efficiently when you... put it in the freezer.

Just knocked this up because the one in the wiki is misleading, it uses saturated solutions which ruin the whole process. Im not entirely sure why because freebase DMT should be more soluble in the NPA then it is in the Basic solution. Please point out improvements in syntax or methodology... if it sucks please point out how.
