hi.
not sure about your d.limo. i use naphtha or xylene.

as for your vinegar mine is also 9% white and it works just the same. and i also use Q21Q21s tek. it is a v good tek imo. i have yielded 1% using this tek on my 1st attempt which i thought was damn good.

edit: one thing i would do is put a drop of you d.limo on a glass dish and let it evaporate away. when its gone check to see if anything is left behind. if glas is clear your good to go.

good luck

Limo does not evap cleanly regardless of purity. There is a u.s. based supplier that sells 98.5% minimum purity limonene that is all natural with no surfacants or or additives. Even at that purity it leaves some residue.

oh. okay thanks i did not know this.

Thats why with aromatics normally you'd salt out. They smell extremely strong & evap slowly & poorly.

yep.

that's what rotary evaporators are for. heating a rotating flask of solvent in a heated water (or oil) bath, under vacuum.

wish i had the money for a rotovape.
Nice piece if equipment.
Maybe sometime in the distant future when i have training & a real reason to have this type of equipment lying around

Sunflower oil is a fat. It sounds a bit strange to use a fat for defatting. Maybe it works, I did not try it. But if I have to judge by the standards of the rest of the write-up, I have many doubts.


If clean hydrocarbons are used and the product is dried correctly, the amount of solvents left is negligible. The above is just FUD, as there are so many volatile chemicals present in the average human inhabited environment that the small amount of resident solvent is insignificant in comparison.


FUD FUD FUD. "stealing electrons from other molecules in your body and suffocating your cells". Sigh.

After decarboxylation, BHO really doesn't have much butane in it. It is a lot harder to get ethanol out of hash oil than butane. What is more carcinogenous at the relevant exposure levels: the butane remnants, the ethanol remnants or whatever crap that results from pyrolysis of the oil? Has the author ever observed the considerable amounts of smog and pollution that tends to accumulate onto cannabis leaves and that is coextracted with most methods?


Nor is a few molecules of butane or naphtha. The body breaks those down too. It creates toxic metabolites to a degree, just like the breakdown of ethanol creates toxic acetaldehyde.


IMHO ethanol in hash oil tastes like crap if you smoke it.


Great chemistry explanations here.


Can I has a non-FUD version?

Okay, so I would like clarification on IPA toxicity. Can someone provide evidence of toxic byproducts left after evaporation? IPA is metabolized into acetone in the body, which the body can breakdown since its a natural byproduct of the body. I have anhydrous IPA. I don't know what the .1% in this product is. Is there really a contamination I need to be concerned with? I use it to remove acacia sacrament from sodium carb. I could use 100% acetone, I suspect this a bit more flammable though requiring further caution. I want toxic exposure at a minimum, so I hope someone can concisely expound upon this suggested IPA byproduct contamination after full evaporation.

To update this post:

I have reviewed the msds and not found any conclusive evidence of toxic by products post evaporation nor was .01-.02% of non primary ingredient of the isopropyl contents shown. At this point in time, I have no evidence to support that there is a toxic leftover after using isopropyl, other than heresay. I will proceed with caution, but assume that within a community such as the Nexus, a few days without someone proclaiming such a toxicity, it is unlikely a concern. It is something that I do take into great consideration. Thank you for the opportunity to be inspired to reach for more.

I'd say you'll be fine with IPA. If it's HPLC grade there's nothing to worry about. Rubbing alcohol may contain bitrex and thus require distillation before use.

Hey! Jumping in for a few questions


1. I'm planning on doing Q21Q21's vinegar tek with sodium carbonate instead of lyme, can I do this? I read about sodium carbonate creating foam when in acidic water, but adding it slowly might do the trick, is it true?

2. I can't find 5% vinegar anywhere, all vinegars at department stores over here are 4% tops. I've been using the 4% with decent results but am I losing DMT because of it?

1. I also have had the same question as you with regards to whether or not the pickling lime could be replaced with sodium carbonate. In my imagination, I have been working with this tek with ACRB and so far my pulls haven't been precipitating well. I heard from endlessness that if you use sodium carbonate as the base, you will have to use a lot of it to get the pH high enough. I think pH papers would be useful in assessing this although I forget what the minimum pH is needed to extract the DMT.
Yes, you will have to add the sodium carbonate very slowly at first to the acidified mix. I learned this the hard way, it foams like crazy!

2. I'm guessing that 4% vinegar should work, maybe you can add a little more than the tek calls for. (But don't over-acidify, especially when working with sodium carbonate as your base.) PH papers could help here too but I don't know the pH to aim for, most of the teks just have an amount of vinegar/water to add?

Thank you for the answers! Very slowly means like one tablespoon at a time or less than that?
I think I'm trying this method today, I can write my results with sodium carbonate later if anyone's interested...

Hey everyone, how's it going?
I have a few questions but some Calcium Hydroxide I can source locally.
It's not pure, it has other additives however I have looked up each compound,

The components are;
Calcium Hydroxide -- 85-95%
Magnesium hydroxide -- 0.5-1.5%
Silicon dioxide -- 0.4-0.7%
Aluminum oxide -- 0-2%
Iron (III) oxide -- 0-0.7%

The magnesium hydroxide is safe to consume, according to Wikipedia, Magnesium hydroxide is a common component of antacids and laxatives. - which I'm not concerned about ingesting if it ends up in the final product.

Silicon Dioxide according to Wikipedia, Silica ingested orally is essentially nontoxic. But again, would this make it into the final product?

Aluminum Oxide and Iron (III) Oxide I looked up and is insoluble in water.

So my final question is, can I mix an excess amount of this 'Calcium Hydroxide' with water and filter out the aluminum oxide and Iron oxide, to leave a basic solution to use for extractions?

Thanks to anyone who can help!

I've also attached the msds.

^^^Have you looked into "Mrs. Wages Pickling Lime?" ... it is relatively cheap and can be bought online and is pure Calcium hydroxide! ... ... ...

Okay soo...

My question involves ammonia and this Syrian Rue extraction. The ammonia I have has two ingredients:

1. Ammonium Hydroxide
2. Surfactant

Now, normally I just use Sodium carbonate during the last step to precipitate Harmaline/Harmine out of the liquid. I read somewhere that Janitorial strength ammonia 10% is sufficient for this step and can be used in place of sodium carbonate (I can't seem to find janitorial strength ammonia anywhere at local stores for some reason). Are surfactants a bad thing? It is my understanding that surfactants are:

"Surfactants (surface active agents) can be broadly defined as compounds which, when dissolved in water, concentrate at surfaces (interfaces) such as water-air or water- oil. The interfacial activity of these substances, which can be explained in terms of their molecular structure, gives rise to a wide range of surface chemistry functions: wetting, emulsifying, solubilising, foaming/defoaming, rheology-modifying, antistatic, 'glossing', lubricity and surface conditioning." SOURCE

If the ammonia was pure, I'd assume that I would dilute it to 10% (assuming 10% is correct) but I get this feeling that surfactants are something I do not want when using a chemical in an extraction...?

Keep in mind that I am perfectly happy using sodium carbonate. Baking soda is cheap and can easily be converted so that isn't the issue. I am just curious as to what kind of ammonia or what dilution of ammonia is needed to create the same results (or similar results) as sodium carbonate...?

Any input is greatly appreciated and I apologize if this should have been posted in the Harmala section but it seems that this is more a chemical question than a Harmala extraction question!

Thank you!

Hi great people of the Nexus.

Just wanting to check which of these is the best choice of Naptha! Thanks for your time

Definitely the first one. But it would be nice if we could get someone else to chime in because I'm not 100 percent sure on how useful cyclohexane is for our purposes. The heptane is fine, awesome. From what I can find cyclohexane acts much like hexane so it should work just fine. You'll probably want to do heated pulls to increase the solubility of all that heptane.

You don't want the aromatic hydrocarbons listed in the second one. That stuff is not desirable for our purposes.

Thanks a lot Flep!

First time i gonna use d-limonene ;
may i ask you if you know about the quality of this one :

sound a really good price
thanks

Hello!

I want to start making DMT again but I could only find pure d-limonene in one store and they don't have it right now. I found something called DL-90, made of d-limonene and nonionic surfactants (and also DL-40 but I imagine it's more impure). Can I use this?

Do NOT use this. The surfactants may be non toxic but you do not want them in your DMT.
They were not intended to be smoked & are potentially toxic when ingested via this route.

Limonene is easy to find online.
The best option imo is a factory that produces limonene as an all purpose cleaner in Florida. It comes in glass bottles & has different purities ranging from 95-98.5%(the 98.5% being minimum purity for the higher purity stuff).

Shipping makes it rather expensive, but it is well worth it.

No surfactants or additives.
