Hey what's going on I hope this post is in the right forum. I am looking to get a few questions answers on the use of hexane for oil production v ethanol the largest draw back to ethanol I have found is chlorophyll residue. Hexane is clearly toxic itself. I understand that everyone has steps taken to heat and remove toxins and stuff when using stuff like hexane but I've read it has long term toxicity. Is the use of n-hexane possible? Being n-hexane has doesn't produce hexane2,5 diode?

also when soxhlet and use sulphuric acid what is the exact type of sulfuric acid? There are 1% 2% and all kinds of others, I just want to make sure I'm not using one that has other impurities cut into it. Also is there less purities in methanol as opposed to ethanol? Are there any draw backs to using either one for soxhlet extraction?
Las question about this in order to remove chlorophyll other than lab carbon? I have read many science articles that go through using activated charcoal and they state that there's a significant loss of CBd and terpenes and they advise not to use, any other ideas?


Last question if I am doing evaporation/separation and I use a water bath to evaporate. What can I do to replicate a nitrogen stream for separation?

I've read of people using n-hexane before for extracts with success. If you're worried about long term effects of hexane, why not just use ethanol and filter with some activaed charcoal? I've had good sucess with doing this. I setup a filter in a long glass drying tube to increase the surface area of the regent to the charcoal and I run it through mulitple times till the solution comes out yellow. If you want to go a bit further you can percipitate out the waxes by leaving this final extract in the freezer and refiltering. I did notice a loss in weight but no loss in potency, at least in myself.

hexane boils at a lower temperature so you shouldn't have to heat your soxhlet as much

I don't know much about impurities I'd assume that the remaing 98% and 99% was just water,
but you what happens when one assumes.
I have no expertise in this subject at all so please take this information with a grain a salt.

also,
I do believe there is a forum for extracts and oils on this board. That may be a better place to ask these questions.

Bro I suggest you do a lot of Googling...seems to me you heard some big words tossed around, but before you start using those methods you should understand them first and what your working with....but yea I love hexane extracts, a lot better than butane imo. But ethanol will always have its place for winterizing..so do butane or hexane to not pick up chlorophyll then winterize is what most of us do...

I have been researching for months.. I've done this before many times with ethanol.. Like I said before the ethanol process pulls chlorophyll that's why it's green... When you use activated carbon to remove chlorophyll the carbon also removes some CBDs and also pulls out many terpenes. I'm trying to find out who has a different process for either removing chlorophyll from ethanol without carbon and without extended exposer to heat (which creates the same issues as carbon). I have heard of people pre soaking buds in ice water to remove chlorophyll but at the same time your loosing trichromes and I don't want to do that or have to pull out has bags to save scraps.
Currently I use a Buchner funnel vaccum flask and vacuum pum along with carbon to filter the ethanol mix..with other steps for ph balancing and bicarbonate adding ...
I have read all the olive oil studies but he research shows you need to take double the amount of olive oil to get the same effect as say ,ethanol,hexane etc.. Because you cannont reduce olive oil.

If anyone knows another process let me know..

I hate butane extracts there are so few people that actually truly know how to do bho extract it kills me. The dispenseries here locally (when they had it) always had hack made bho... They would do the basic bho extraction, put pans in water scrape it and sell it!

When you use hexane, have you ever notice any kind of residual taste? Can you tell the difference in strength when you use hexane as opposed to butane? I know that ethanol is the only non toxic chemical you can use to remove thc,CBd and terpenes without degradation or loss of CBDs.. It's just the whole carbon step pulls out so many needed CBDs and terpenes that studies have shown skipping that step is more worth it medically than going through the carbon removal.

Ugh guy go read "what is a purge" the "iso" thread and maybe "winterizing bho" .....(all in this section should be 1st or second page) someone needs to get some damn stickies up

Actually though something that I'm not sure has been mentioned is hexane does have a lower ppm sensory threshold and is a bit harder to purge especially without a vacuum but the etoh wash removes that anyway..most utilize the winterization as the purge also...

UGH GUY! Read the actual post... I don't get what your not getting. I'm not looking for ways to purge... And if you didn't read it in the first two posts.. When you do heat purges even low heat purges in vacuum chambers you loose CBDs, terpenes and thc degradation occurs.... I'm pretty sure I know what the heck a purge is. All I'm trying to see is if anyone knows of a chemical that can be used that doesn't leave any residual toxins.... Basic science is that even when using naptha the residual toxins left over are still low enough for the cannibus to counter act any negative effects.. But the point is no matter what you do to purge or anything there's still crap left over.

Purging, winteriziation nor ISO has anything to do with anything I am trying to find out.

I am trying to find out if there is another way to remove chlorophyll when using ethanol other than carbon. U can't purge out chlorophyll, nor can u winterize it. And ISO is made from isopropyl which always leave behind crap no matter how much you purge.

Well there's nothing else I can say...maybe someone else can chime in and present it in a better format...... your ignorance is frustrating me....ima out

I meant to say that doesn't leave any toxins but also doesn't pull chlorophyll.... If anyone's educated on n-hexane and can answer if it's successful with good results and no issues with left over chemicals or taste

I like to use ethanol to clean some grades of ice water and kief. I usually add 5-7 grams of this hash to 113 grams of Ghee and make a batch of cookies.

If you didn't properly purge the Hexane, you could smell/taste it (IMO). I would use HPLC grade Hexane, I believe it is easily purged.

Our livers manufacture Hexane 2.5 dione out of n-Hexane.

We use Hexane for alchemy and extract with it in class. Does a good job and is highly forgiving, but is harder to purge than butane, because of the higher Van der Wall forces with the larger molecule.

Either ethanol or methanol will extract a boatload of chlorophyll in a soxhlet. You need a non polar solvent.

Concentrated sulfuric acid.

You can polish the extraction to remove the chlorophyll, using a Hexane/brine wash, but it is better not to extract the chlorophyll in the first place, because you will lose monoterpenes in the polishing operation. http://skunkpharmresearch.com/getting-the-green-and-waxes-out-afterwards/

Any dry inert gas. You might consider using vacuum to cold boil away the solvent.

Seems to me if your using ethanol currently and pulling enough chlorophyll to worry about your doing something wrong in the first place, or your just very anal. I'm not trying to be a dick, but I've made, and seen absolutely beautiful alcohol extacts that were very clean from both chlorophyll, and solvents. My extracts, and I believe qwizo's as well are COMPLETELY purged and clean in 24hrs most of the time. I know this isn't exactly what you asked, but I think your question has been answered specifically be fadedawg above. Rather then worrying about using a different solvent I would work on refining your tech to get less chlorophyll in the wash.

I dont know know where you've seen straight ethanol extraction without using carbon at some step to completely remove all the chlorophyll ... ETHANOL REMOVES CHLOROPHYLL ITS THE ONLY EXTRACTION CHEMICAL WE USE ON MARIJUANA THAT PULLS CHLOROPHYLL!!!! Clearly imaging honey oil that has absolutely no chlorphyll is not a freaking issue!! I'm trying to figure out a way to remove chlorophyll without taking a carbon removal step!!!!! Jesus lord if you seriously have no idea what your talking about quit chiming on this board there is only one person on here that has responded to the point where they clearly understand what I am talking about as well as had a sensible answer so instead of wasting my time arguing back and forth with people that clearly have no idea what the heck is going on I will talk with the one who has actually had some background in science.

I hope oped you hall have fun purging chlorophyll and using the super special ethanol you've developed that doesn't pull chlorophyll.... Silly me I must have been doing something wrong all this time along with EVERY OTHER PERSON IN THE FREAKING WORLD who has ever used ethanol to extract oil..

Thank you first of for actually understanding and replying with a response.

So I understand that even the toxins left behind when using hexane and methanol aren't toxic enough to create issues, actually thecannibis properties are so strong that they counteract any toxins. So cleary it's safe to use but I'd rather not have any toxins left at all if possible. Which is why I come back to ethanol but clearly you know that any carbon removal removes terpenes as well as CBDs .

So this is the basic process I have used after I have my extract to remove chlorophyll and balance ph.. Http://www.druglibrary.org/medicalmj/hash/making_marijuana_cannabis_honey_.htm when you mention sulfuric acid.. Is the step in this process the type of step your recommending to use sulfuric acid for as well?

Lol........

"using the super special ethanol you've developed that doesn't pull chlorophyll.

I'm trying to figure out away to remove chlorophyll without taking a carbon removal step!!!!!" (Don't extract it to begin with and fade answered how to remove via hexane/saline wash)

But uh LOL


"Jesus lord if you seriously have no idea what your talking about quit chiming on this board there is only one person on here that has responded to the point where they clearly understand what I am talking about"

I think we all understand what your trying to say....you sound like that moron rick simpson..."why purge, thc neutralizes any and all toxins"haha
Go read the pages I told you and learn some shit...or at least reread what fade and what anyone else said....none of us are extracting chlorophyll

That process is for Isomerizing oil, not polishing it. No acid is required to polish.

We only isomerized once, because the results were pretty non spectacular. The strains that we used were low in CBD to start with, and straight THC isn't all that wonderful. It is the entourage of terpenes that are responsible for the effects, including the CBD attenuating the effects of the THC.

It is worthwhile to acetalize using sulfuric and acetic anhydride, which you might check out athttp://skunkpharmresearch.com/thc-acetate/
