Why is the first pull alway's the best ?

Migrated topic.

I don't know if this is true for everyone else, but every time swim does an extraction the first pull is alway's the cleanest. Sometimes the second is just as clean, but usually by his third pull the naptha gets the n-oxide greenish tint to it and will reflect into the final product, and a re-x doesn't remove the n-oxide.

You can store bark for a yr. and extract clean white spice, but if you let your basified solution sit for a few day's you're pulling green spice.

Is it just that the salt is much more stable than the freebase?

Can swim get his third and fourth pull just as white as the first???
 
I noticed that too.. first pullz are always the best. actually i dont see any point making more than 3 pulls if extracting 50-100gr bark. And i also noticed on first pull naphta turns yellow. on third pull its almost colorless. But not green as u said. So i always understand if the pull is gud from the color of naphta. if its yellow its gud :) you may add a little extra naoh for your 3rd pull to increase the yield tho. But i mostly dont do that

Actually, it is swims experience that when he does his pull and the naptha is crystal clear (which is usually on his first 2 pulls), is when he get's the cleanest or whitest spice.When he does his 3rd pull, usually the basified solution has been sitting for.....anywhere from 3 days to a week, and that's when the naptha get's a greenish tint to it. The final product might be slightly green'ish, or yellow'ish, or sometimes tann'ish.

In swims experience the clearer the naptha, the whiter the spice.

swim thinks it's because the longer it's sits as a basified solution, the more sensitive the spice is to oxidation, but he's not sure.

He thought that some of the sophisticated chemists might have an answer, and also a solution to get the 3rd & 4th pull just as white. [
 
It's because you are pulling out the bulk of the alkaloids with the 1st pull, the DMT is highly attracted to the non-polar solvent, so the Naptha holds as much of the alkaloids as it can.
But the solvent can only hold so much DMT, so you do the 2nd & 3rd pulls to "mop up" the alkaloids that didn't fit into the first pull. But since the DMT is no longer filling every space in the solvent there is room for more oils & fats to come along for the ride.

Your subsequent pulls are dirtier because there is less DMT left in the solution to be picked up by the solvent, which also means there is more room for other crap & impurities to get in there with the DMT.


It's simple really, you can't fit a lot of stuff in a box that can only hold a little stuff. If you put less stuff in the box, there is more room for some crap to fit in the box, with the stuff as well.😉


BTW, if your Naptha is turning colors when you use it to pull alkaloids out of a solvent, try defatting the bark solution with Naptha...BEFORE BASIFYING it... To pull out the oils & fats that are also attracted to the non-polar solvent, so they don't come out with your DMT.
Then you basify the solution & when you pull out the alkaloids with your solvent, the fats & oils are gone already, so they don't end up mixed into your DMT.:d

The funny thing about it is that swim ALWAY'S does 2 to 3 defats before basification, which would leave even less fats,oils,lipids, or whatever left over gunk is left in the bark (which MHRB is known for having very little in relation to other containing plants).

I understand that 65% of the alks get pulled on the 1st pull, 20% on the second, and roughly 15 % on the 3rd. So what would be the answer, to use less solvent on the latter pulls? I really don't think it's other stuff in the bark that's getting passed through to the solvent, but rather something to do with oxidation, although i'm not sure. :?

Some what, by washing your solutions.

yeah,swim does SC washes aswell but still never turns out as white as the 1st or 2nd pull.

Swim alway's keeps his white spice seperate from his yellow, infact he has accumulated some yellow spice over the last yr. or so, because by the time he's finishing up with his clean spice, he'll do another extraction and never gets around to smoking the yellow stuff.Mabey swim will just throw all of the yellow spice together, and re-x , and then give it to a friend.

Spice karma :)

still curious as to why he cant get the 3rd pull as clean as the 1st and second.

I always do three pulls...then add then together...do a sodium carb wash (most of the time)...freeze precip.
The fist one is usually 100ml, the 2nd & 3rd I use around 75ml using an A/B tek (vovins) & 100-120g of MHRB.
Comes out nice & clear/white every time. Worked fine with the D-Limo/FASA tek too.

Why keep them separate?

swims, still uses marsofold, although he defats and also does an sc wash.

Swims main issue w/ vovins, is that swim prefers to yield as much spice as possible,so as not to have to extract as much, due to lack of time and sometimes privacy. He usually will extracts from a 1 lb of bark at a time.

It is difficult for swim to work with that much solution,using a sep funnel for the defats,basification because your dealing with almost a gallon of solution.....so he's been trying to tweek his tek to be somewhere between mars & vovin. Instead of using a sep funnel to mix all the solutions he uses a gallon pickle jar.

He started getting tired of pulling the saturated solvent w/ a glass turkey baster (because that last bit of solvent is a pain in the arse to pull and it drives swim crazy), so this last time he let the basified solution and solvent seperate in the gallon jug and decanted the solvent w/ some base solution into a smaller jar,which then went into the sep funnel.

That was the first time he tried doing it that way (the decanting),which is still inefficient because even when swim decanted there still remained a thin layer of solvent that he couldn't get out of the jug.....because the base solution is heavier than the solvent.

Swim is still tweaking his tek.....trying to find a happy medium between mars & vovin's. The main issue is working with a gallon of solution and finding an easy way to seperate without the old turkey baster.

I know i went a little off topic....i guess i'm just venting frustration. Trial and Error.
