Pulling with Non-Polar Solvent

I have a question: what does the solvent pulls process look like? Am I correct in thinking it's gentle, slow mixing? The first extraction is 8 hours after using the lime. The second is 24 hours later, and the next one is 48 hours later. I have 100 grams of MHRB on the table. Am I calculating correctly that the first extraction requires 200 ml of solvent. The second extraction requires another 200 ml, and the final "a pull" also requires 200 ml of solvent, so I'm using a total of 600 ml of solvent per 100 grams of MHRB?
 
If you're using a method with lime paste then you'll need to mash the solvent into the paste. With a lye-based extraction that's more liquid in consistency a gentle but thorough rocking and rolling action is considered more optimal, to help prevent formation of an emulsion.

Your solvent volumes seem reasonable enough, just be aware that about 100mL of it will disappear into the paste, and/or evaporate.

Sounds like you're doing the Q21Q21 Tek 1: Jim Jam Party
What the tek says about the non-polar solvent pull:
Each time this step is done it is called "a pull" and the step is used a non-polar solvent to dissolve the Jimjam DMT from the basified bark, this separation is essential if a pure product is to be extracted


IMPORTANT NOTE: Solvent loss is very typical in limeteks, it is basically a necessary evil you need to accept. Losing 50-100ml of solvent during a pull with a large batch of MHRB is quite common for me. Just make sure you have much more solvent than you need and you won’t have a problem.



When to do your pulls:

I recommend to do the first pull after the lime has had 6-8 hours to work on the bark, this is the most efficient time to get a quick good yield. A pull done at this time usually gets you around 30-50% of the total DMT in the MHRB.

If you do a pull right after adding the lime, it will work, but will be more like 10-25% of the total DMT

After your first pull, I recommend one at ~24 hours and one at ~48 hours. These 3 pulls together should yield you 80-90% of the total DMT

Pulls after that tend to be rather inefficient. If you want to extract all the DMT, I recommend 2 additional pulls: at 1 week and at 2 or 3 weeks. All 5 pulls combined should yield you over 95% of the total DMT.



Step 1: Add at least 1.5-2ml d-limonene or xylene for every gram of MHRB. (75-100ml for 50g)

Step 2: Mix so the solvent contacts all the bark-mix as thoroughly as possible, it should not mix into the bark and should remain transparent.

If you have it in a bowl: mix with a spoon or chopstick. You can mix it pretty well without getting an emulsion in my experience, but no need to be vigorous when mixing.

If you have it in a sealable container: you can just roll the container around in your hands to mix it.

Be very careful not to mix too vigorously or you can get a nasty emulsion (all of the solvent stuck in the bark mix).

Mix it well several times over 40-60 minutes. (I’ve done experiments that suggest pulls under 30 minutes do not completely dissolve the DMT-freebase into the solvent.)

YOU DO NOT NEED TO STIR CONSTANTLY, ONLY PERIODICALLY.

Step 3: Separate the solvent from the lime-bark mix. You needn't be too fussy about getting 100% of the solvent, 90% is a good goal. Trying for more usually results in frustration and getting bark-mush in the solvent.

If you have it in a bowl Prepare a funnel with a cotton ball in the neck over a solvent-safe container then very carefully pour the solvent into the funnel.

If you have it in a sealable container: Prepare a funnel with a cotton ball in the neck over a solvent-safe container then use a turkey baster or pipette to suck up the solvent and squirt by squirt put it through the funnel.

Note:Although you can do another pull with fresh solvent while you are working with the pull you just separated, it probably is not worth the effort and is just wasteful.
