This was my third extraction, and although I understand more each time, improve my equipment and techniques im left with 500mg of goo from 200g acrb powder.

heres my TEK

1. 100g ACRB will be gently simmered in 500mL pH 4 acetic acid solution for 30 minutes and allowed to cool for 30 minutes. The tea will be filtered, the filtrate saved and set aside. The Filtrand will be returned to 500mL pH 4 acetic to be boiled again, repeating the step 5 times.
2. Filtrand will be simmered once in 500mL H2O, filtered and discarded.
3. Combined filtrate pH will be adjusted to pH 4 with glacial acetic acid
4. 100mL Naphtha will be added to the combined filtrate, stirred gently for 15min, and discarded
1. Repeat 3x
5. The remaining acidic solution will be reduced to 400mL with a gentle simmer
6. Solution will be basified to pH 12 with concentrated Sodium Hydroxide Solution
-.If necessary, will be reduced to 800mL by evaporation
7. 150mL Naphtha will be added to the base, stirred gently for 15 minutes, separated and retained
1. Repeat 5x
8. Resulting 750mL Naphtha will be washed 3x 100mL pH 9 Sodium Carbonate Solution
9. Washed Naphtha will be reduced to 300mL by evaporation and frozen for 48 hours
10. Remaining naphtha will be poured off crystals and saved for a rainy day
11. Crystals will be allowed to dry completely before weighing and bottling.


Now heres my de fat pics, it looks like an emulsion to me, but this seems unavoidable. Either way an emulsion shouldn't take a toll on the dmt salts.
I seemed to have the best yeild with my first extraction which had no step 1 and 2. Just soak in warm acid, no filtering either.

Had the best luck with this tech follow step by step... (scale down if need be)


NOTE: once again it is common to get up to 20 grams or more of DMT crystals if this is followed correctly a lifetimes worth
MATERIALs:
-1kg Acacia confusa root or trunk bark (preferably root bark)
-naphtha/ petroleum either 1 gallon (make sure it evaporates clean)
-vinegar (white distilled 5% acidity)
- 1 can NAOH/lye/caustic soda 5%
-rock salt/NACL (non iodized)
-glass turkey baster
-gallon mason jar or glass gallon jug MUST BE GLASS (Pyrex is best but other glass will do just be carefull while heating)
-1000ml glass crystallization jar (best if wide mouth mason jar and easy to scrape sides with a razor blade)
-square Pyrex baking pan
-Chemical resistant gloves and goggles (A MUST)
-stove
-2 large pots

OPTIONAL:
PH METER
SEPARATORY FUNNEL
FUNNEL

SAFETY:
-NEVER HEAT NAPHTHA ON AN OPEN FLAME EITHER DOUBLE BOIL OR USE A HOT PLATE
- ALWAYS WEAR YOUR GLOVES AND GOGGLES WHEN WORKING WITH SODIUM HYDROXIDE NO JOKE IT WILL MAKE YOU GO BLIND AND BURN HOLES IN YOUR SKIN, WHEN ADDING LYE TO WATER ALWAYS ADD THE LYE TO THE WATER SLOWLY! SODIUM HYDROXIDE CREATES A EXOTHERMIC REACTION THAT MEANS IT CAUSES HEAT AND CAN CRACK THE GLASS CONTAINER THAT ITS IN


PROCEDURE:
NOTE: you can scale down if you want to the only thing you dont scale down is the amount of time you boil it
SET UP: clean up you work space its best that everything is done in the kitchen
- take 1kg bark and cut it up into the smallest pieces possible use a coffee grinder or blender if possible.
-freeze bark and thaw 3 times in freezer.

PART 1 ACID COOK
the objective of this step is to convert the DMT into its salt form so that the polar solution/water absorbs the DMT easier by using Acetic acid/vinegar converting the DMT into DMT acetate

STEP 1: take 3600ml distilled H2O and add 400 ml vinegar making the PH approx 4, put the 1kg of bark in an appropriate sized pot (pot A)and add the vinegar and water solution. boil for an hour and 45 mins (don't be afraid to boil rigorously, also make sure there is a lid on the pot)

STEP 2: pour the bark and water threw a strainer and transfer the liquid to another pot(pot B). add another fresh 3600 ml water and 400ml vinegar into the first pot (pot A) and boil the bark again for another hour and 45 minutes. while you are doing this boil pot B without a lid to reduce the volume

STEP 3: repeat step 2 two more times you want to do a total of 4 acid boils.

STEP 4: reduce the contents of pot B which in total should be 8000ml to 2500ml

STEP 5: wait for the reduced red liquid in pot B cool down and then pour into your gallon glass jar or jug and place in fridge (make sure the liquid in the jug is completely cooled down before proceeding to the next phase of the procedure.
NOTE: you should now have 2500ml of liquid.

PART 2 BASIFY
in the next part of the procedure you are converting the DMT acetate into its freebase form by making it basic with NAOH/lye so that it will travel from the polar solution (water) into the non polar solution (naphtha)

SAFETY NOTE: for this part put on your safety goggles and chemical resistant gloves remember lye can make you BLIND. i can not emphasize enough to wear the god damn safety gear (excuse the language) but seriously just wear the goggles and gloves if you value your eyesight

STEP 1: weigh out 250 grams of lye

Step 2: SLOWLY add the lye in 25 gram increments every 2 minutes to your red solution inside the gallon jug(in this part you will actually see the freebase alkaloids precipitate) your solution should first turn grey and then turn black. NOTE: the contents of the jar will begin to heat up when you start adding lye, if you add the lye to fast the jar will explode and spray caustic lye everywhere wear your glasses. Proceed to the next phase immediately after all of the lye is added do not take a brake


PART 3 EXTRACTION
the point of part 3 is to extract the DMT from the polar solution into the non polar solution because water and naphtha do not mix together they are the perfect solvent for this procedure.

STEP 1: while the contents of the gallon jug are still warm from the addition of lye (if it has cooled down its ok just double boil it untill it is warm be carefull to not heat it to the point that the jar cracks it just needs to be warm not boiling) measure 1000ml of naphtha and add it to the jar youl notice that it forms to layers the naphtha is on top the water is on the bottom.

STEP 2: shake the contents of the jar vigorously for 1-2 minutes and then let it separate

STEP 3: repeat step 2 10 times (keep the contents warm during this time by occasionally placing the jar in the double boiler DO NOT heat he jar with an open flame as it contains naphtha witch is extremely flammable) during the last shake roll the jar gently to avoid emulsion and then wait 5-10 minutes or until the water and naphtha have completely separated before going to next step.

STEP 3 1/2: (optional) Basically:
1. A/B or STB extraction -> NP solvent pulls
2. Add dry ice 3x or until nothing else precipitates
3. Warm water bath to raise to room temperature/redissolve DMT
4. Decant solvent away from carbamates
5. Freeze precipitate/FASA/evap solvent

STEPv4: take your glass turkey baster and carefully suck up the top lair of naphtha and transfer it into your appropriate sized crystallization jar (be careful to not suck up any of the basic water layer if you do there will be impurity's not to mention lye in your final product) dont worry about the little bit that you cant suck up with the baster youl be able to salvage it later or if you want you can suck it up with a glass syringe.

STEP 5.: take the jar of the DMT saturated naphtha and put it into a dark cool area (thats right no freeze precipitation) if you did it right once your jar starts to cool down it will turn milky white wait 12 hours and when you come back youl see that the naphtha is now clear and in the bottom of the jar there is a lot of crystals waiting for you usually 2-4 grams per pull.

STEP 6: take your funnel and place a coffee filter inside it and pour the jar of crystals slowly into it place the coffee filter with all the crystals cacked on it and leave it somewhere to dry. put the naphtha back into the jar and put it into the freezer for 24 hours to precipitate more crystals (the crystals that fall out at room temp are much more pure than the freeze precips when you freeze precip ther is much more plant oils and NMT that come out along with the DMT so if your thinking youl just go strait to freeze precipitating DONT)

STEP 7: repeat step 1-6 except reuse the same naphtha over and over untill no more DMT is being pulled. the reason why you reuse the naphtha is because it works alot better when your solvent is saturated. also after the third pull add 100 grams of rock salt to the gallon jug to make the water more polar this helps pull even more DMT. when your done with all of your pulls you can take your naphtha and evaporate it to yield the DMT NMT bonus


PART 4 ENJOY

Yes iv read this TEK and to be honest its basically the same. I wonder if there is any small errors that can make a huge change in yeild results

So you dont do a de fat? I guess you clean it up really well with the second A/B right?

Freeze precipitating 300ml from 200g seems too dilute a final amount , 50-75 wouldve been much better to ensure saturation. Did you check the NP clouds when you blow on it?
Also , NMt is slightly soluble in basic water so you may have washed some of it out with the sod.carb wash. Not much Im sure but it all adds up.
Better to backsalt then rebasify in a clean solution. It saves naptha/solvent and produces a clean extract.
Other than that the other steps are good.

Yea I evaped down to about 70ml before freezing. the first three pulls were very cloudy indeed. So by back salt and rebase you mean do another A/B rather than the water wash? would you still do a de fat?

personally, cover and seal and let it sit at room temp after extract to get the purest crystals, and then salvage anything from the solution in the freezzzre for the extra goodies

A mini acid-base yeah, no need for a de-fat. ACRB is variable it maybe you just have high NMT/DMT ratio and a lower contnent of alkaloids.
