d-limonene and extracting

There is some interest in maybe using d-limonene in the oil extraction process... feel free to add any info or comments towards fulfilling this goal here in this thread. I have been combing the web looking for more info about what other people are doing, and thought the conversation could be better if more could join in and offer what they have seen/know, or may find, so I am starting this thread. Please try to stay on topic, as we know of many other ways to do extractions and there are already existing threads about those topics. This is a AT YOUR OWN RISK topic. Please use common sense and be safe...

Here is one post I found about using it as a quick wash method... not sure if I agree with this method entirely, I do not have enough experience with the D-lim to know how safe this is, but I thought I'd go ahead and post it for discussion purposes...

I would like to report my findings using d-limo on some beasters.
This will be done in comparison to my QWISO done on the same bud
Smell: no noticeable smell of oranges
Taste: cannot be done definitively (i smoke with bud as well) but not bad at all
Consistency: slightly softer than the QWISO, the QWISO oil is slightly more "tacky"
High: same as QWISO, possibly slightly stronger
Ease: Same as QWISO
Quality: BETTER! Less chlorophyll!


Both extractions were done as follows:
1. Put bud in jar, add solvent and shake for 1-2 min
2. aspirate solvent and dry under dehumidifier
3. decarboxylate hashoil in oven @250F for 1-1.5 hrs
4. scrape and smoke!


d-limo hashoil has a higher burning point than the QWISO but other than that I have noticed no difference.

I will do a second wash on the bud to determine how well the d-limo picks up chlorophyll. If d-limo picks up more Cannabinoids faster than ISO/Acetone/Naptha it would be better to use, however as it is, I see no reason to use this expensive solvent.

Also, my d-limo evaporates cleanly under heat

am forwarding this for t-dub

this post is from Wat Tyler also from the tami thread

EDiT - for me the ultimate goal is to rewash the limon (gonna use for short) with another mild solution that the limon is soluble in, but the oil isn't. this way keeping it chem free completely after my tami runs.

i added a few drops of pure lemon essential oil to my eth washed BHO of ABV. It tastes very good now and runs well in my Omi.

should i try d-limo washing of BHO to filter out waxes instead of using everclear?

OK so basically you are using D-Lim as a "natural ISO" to filter the waxes out? then re-evaporate D-lim...Am I following correctly? Cause I see no interest in "flavoring" my extracts...they are pretty darn tasty already! ROFL

So far this is my take on it. Tdub did an experiment, adding some drops of D-lim to some existing oil, and it caused the solids to bond and separate, in a short explanation. Then he added that to a iso wash, and re-filtered it, and got a much cleaner oil. This is what I am interested in. I do think the heat purge is needed, I use a coffee cup warmer and a stainless steel cup, and just run small batches. Works great for the purge, nice slow heat. I have not taken a temp reading on the coffee cup warmer, our laser reader needs a new 9v. I can say however, I have been using it consistently for months with good results.

I want to stay away from more volatile solvents, but desire a good clean oil.

Not to geek out on you guys but it appears that this solvent has a particular affinity for precipitating things out that we do not want. Thats why TetraLabs uses it as part of their Pure Gold process. The fact that they describe their process and have to conform to the law is very illuminating if you think about it a while. They HAVE to do certain things because of this . . . I think the quest for a home made product of this type, maybe with reclaim, might be a worthwhile pursuit. AND, if Tetra Labs is using 5% of this in their final product there IS a reason. The effect I get from my cleaned "reclaim" is much better. Click, read . . .

OK so I do not get the use of ISOing again the D-Limed oil... T-Dub can you give me the point of that process please?

EDIT: Yes I have been discussing with the Pure Gold guys on the MMJ events around 4/20 and people on these boards know them pretty well I can assure you! Have red this month ago, but still not convinced at all by all the "it add something" ...either to the high or the taste (not a good thing IMO). BTW T-Dub, a lot of companies add 5% of BS to their product, just to sell...What I can understand is how it takes out waxes and makes your product purer and how it is a better solution for this then ISO!

I should have some of this next week, and just in time, I also have some trim to do a wash on.
so still trying to decide, should I stick with Iso because it's less expensive, or go with ever-clear. I got such a good run on my first try doing a frozen quick wash w/ EC instead of iso. Best I've made yet, and I am wondering if it will make a difference w/ using the D-lim. I can get 99% iso online, but it's about as expensive as EC that I can pick up locally.

I am still a bit fuzzy about the second wash too. This all came up for me last night, so I have a lot of research to continue to do. I think the second wash is to allow you to use minimal amounts of D-lim and have a liquid to filter. At least that is how I am understanding it. Also gives you a low heat purge process, which I do think is key to making a good clean oil, under these conditions.

Look we are experimenting here, no "processes" (yet), stuff just happened the way it did . . . but we are, together, going to nail this down.

treading new territory for sure, just glad there are some big boys already using it, so we have some data to work with... I need to go comb the web some more for discussions elsewhere. I hope to turn up more useful info...

Good answer.. I like experiments!

LOOK at this, these guys are making their product out of schwag . . . thats why the cannabinoid profile is so static over time . . .
PureGold: our core active ingredient

TetraLabs is the culmination of a years-long project to explore methods of producing ultra-pure cannabinoids by recycling cannabis plant materials that were unsalable by growers. We demonstrated feasibility three years ago, but could not produce sufficient quantities for patients beyond the trial groups1. We then spent several more years refining our process, learning how to make sufficient quantities and establishing a collective to enable more patients to benefit.

Also D-lim good for controlling mites and other garden pests for you growers...

Yes T-Dub...and again please read this! I have red the whole tretralab site on 4/20, after discussing with the owner and founder for 5 mn. at Delta9's booth... and I am not saying it is not working just that the "secret ingredient of Coca-Cola is maybe not the reason of its success" (not sure that metaphor is a clear , sorry) !

And about using swagg: you must know a lot of people are doing CO2 extractions not even with swagg but with trime..and reaching 85% of thc in their tested oils, so this has nothing to do with D-Lim usage IMO...

Well its simple. When I vaped the reclaim before I cleaned it, it gave me a weird little headache. After, it didn't.

Edit: And there was definitely a little "sparkle" on the uptake . . .

maybe i can clarify something. i don't care if PG is using limon, nor does their process have anything to do with mine as i am not doing fractal distillation, nor do i have a super critical extractor. i think the main reason for using this is to minimize chemical processes and stick to food grade as much as possible. i started using it to clean up my tami. any solvent is going to have different precipitates, but if the last process is limon instead of eth or iso, not only is it, imho, a "cleaner oil", but there is also something to be said for the chemical connection 'tween thc and limon. from my old lsd days (pre-internet) it was also common to imbibe oj to increase the high. as thc works similarly to lsd on the brain, there MIGHT be a connection. as i said in the tami thread, it might been placebo effect, but the stuff i cleaned up wtih limon seemed to hit slightly higher and clearer.
as the more people try this, the more data we can compile. we aren't saying we have all the answers or that this is the best thing on earth or for everyone. we aren't sure so we are gonna experiment.

I'm following all this and I am also the kind of guy who does his experiments! As stated I totally understand your thinking and where you are going with D-lim. as a food grade wax cleaner vs. ISO, eth or acetone!

As I am very interested in achieving the best end product myself with the help of the whole community, I was just saying that:
1/ lets not use data on D-Lim "benefits" from PG as we are not using at all the same process!
2/lets try to be "scientific" in our observations & statements

Thx for your answers to all!

Right . . . lets be scientific, well if you READ the links I provided it gives a HUGE scientific insight as to what these guys are doing and why. I say again, if you understand CA law, and what these guys are doing you can put together a thought experiment, in your mind, that will allow you to understand what they are doing and why. They say their process takes 3 weeks. Why? INFUSION, and they admit to using grape seed oil. So. They are starting with bubble hash and then using a 3 week infusion to grape seed oil, then probably refining with some kind of alcohol wash, d-liomo, and centrifuge and filtration action, maybe even through activated carbon granules . . .

The point of all of this is to examine the organic chemistry involved and see if we can improve our medicine with it.

can fully appreciate this.
for me using it to clean bho was a little more acrid than i would have liked. also i did find that it "seasoned" my nail. subsequent hits had a little orange flavor. acridity was gone tho. was gone within a few dabs, tho. am guessing that it is gonna be better for ABV or reclaim than as a first or secondary solvent. seriously think the best way is to get the limon mixture filtered and evapped and then find something that the limon is soluble in, but our oil isn't and which also has a low boiling point.
i'll probably do a trim run of bho, scrape and purge as normal. cleanup with limon, vac purge that. mix together first scrape and purge. see if that evens the flavor and makes this a little more viable for bho until then. lots of net reading to do in the future.

an interesting looking effect happens when you put a few drops of d-lim into a pie dish and then run BHO into it. I was trying to add flavour while making the extract of regs, but what it made looked like a broken butter sauce as the butane was evaporating as if the butane oil mix was separating. the finished product had a SillyPutty texture.

that's a nice link jam! missed that the first time!

Thanks for sharing that. The texture of my reclaim went from "black glass" to beautiful, deep amber, taffy. I can do anything with it now, even string dabs . . .
