Hexane Honey Oil extraction and alchemy

[IMO]

more excellent info gray wolf, appreciate having a thread here that consolidates some of the bits and pieces ive read about hexane before.

i see you did 3 ethanol washes for the hexane used in your acetate- were you guys just being extra cautious or do you do that with every hexane wash?

thanks again

ps- perhaps the sexiest 'blow job' pic ive seen...

It took that many washes to get the hexane below detection levels.

I'm kicking myself for getting a C in chemistry in high school right about now...

SumBitches would not let me take High School Chemistry after 1 little 'incident'....oh well Gray Wolf is a better teacher anyway...

Wish ya'll could have had the hard bodied sexy wench, with fine minds, as well as a nice ass and wammas that I did.

Lawrd knows I loved that class enough to worm my way into being lab assistant. Hee, hee, hee, snicker, snark, snort, ahwooooooooooooooooooo!!!!!!!!!!!!!!!1

the general procedure for making aspirin out of salicylic acid.

Where, btw, acetic anhydride (with or usually without some added glacial acetic acid) is the usual solvent, and the amount of sulfuric acid (when used) is usually measured in drops on that kind of scale.

In 1941, Roger Adams used 1 drop of sulfuric acid to completely isomerize/otherwise change 1.94 g. CBD in 35 ml. cyclohexane, by refluxing for an hour. The product was probably mostly delta-8 THC. Tosic acid gave the same product. Mechoulam, with NMR capabilities, used tosic acid to change THC to the delta-8 isomer.

So, sulfuric acid is not used in the old (decarboxylated) Cannabis extract acetylation articles I've seen, and acetic anhydride is the solvent. 3 volumes of acetic anhydride and a 2 hour reflux may yield no more than 2 volumes and 15 minutes.

Yup, good point brother GOJoe, the sulfuric use in acetalizing is small and was only used as a catalyst!

We did isomerize with sulfuric, and I will post that procedure next, after I sort out my bad notes. While disappointing as far as improvement in medicinal effect, it had interesting properties.

Great writeup GW< how much do you pay a gallon of Hexane? I saw it online for over $300 per gallon.

BTW, i don't care what solvent you use, as long as you know what you're doing and make/purge it well, it will be great. If you don't, it will suck.

In other words, solvents don't make bad oil, bad oil makers do.

Good point!

$60 per 4 liter, for HPLC reagent grade at the local scientific supply.

That explains sssooooo much.....mine was so ugly she looked better with all her facial hair burned off...ooopsy

Actually, mine had a light mustache, which I now know meant she had a higher than average testosterone level and a high sex drive. The sort of things that young boy's wet dreams are made of.

We haven't found a better method for alchemy and Mother's Milk just doesn't work. Always open to suggestions.

pe?

HI Gray Wolf. You seem to be a bit of an expert in chemistry of cannabis

I currently make RS Oil, and as you know since you said you have made it yourself, it is a fairly simple process. Basically soak plant material in solvent, strain, then cook in rice cooker type device until you get the oil. I've made oil like this and had it tested at 60% THC, however it has a very thick dark color to it, and I believe it is unsuitable for smoking due to high chlorophyll. So, its basically meant for edibles only.

Is there a way to remove chlorophyll that you can speak of? From what I was thinking, if I could somehow do an extra step after I have soaked the plant material in solvent, that could remove the chlorophyll. Unfortunately, it looks like your acetate method is probably too complicated for me to ever do. So, I'm looking for a simpler method that would give me a result of something on par with BHO honey oil, ie: can be smoked but not acetate.

Thanks! Anyone who thinks they know can chime in too. I'm researching a bit as well trying to decipher Cannabis Alchemy http://www.scribd.com/doc/7720803/Cannabis-Alchemy-
I'm wondering if petroleum ether is possibly what I am looking for, or possible even a water/salt water. anyways, thanks

If you have lots of chlorophyll, I infer you are using alcohol to do your RS extraction.

If you freeze the material and chill the alcohol, Ethanol will produce an amber extract in the 3 minute time span Simpson recommends.

If you use Isopropyl, you might freeze and cut your soak time to 20 seconds.

If you already have the ISO oil with chlorophyll in it, you might redissolve it in 190 proof and stick it in the freezer for a couple of days, before straining it through a coffee filter. That will remove some.

If you then stick the alcohol mixture in strong sunlight, it will break down the chlorophyll rapidly into its byproducts within a few hours, which are amber and don't taste green.

 

[Blue Tail]

For extraction I simply fill a jar about 2/3rd full of material that I have broken up to about coarse rolling size, and fill the jar to the 3/4 level with hexane. I shake well, loosen the lid to release the pressure, seal it again, and set aside. I periodically repeat the shake and pressure relief steps, for up to 12 hours.

Sensei Gray Wolf,

So you do no refluxing of your ground material in the Hexane? Just a long soak?

Maybe a better question would be is there any value in refluxing the material using Hexane?

Thanks for your very informative posts.

Best Regards,

BT

As the material that we are harvesting is on the outside of the plant, I haven't found reflux or soxhleting necessary.

and I thought I was the only one on to this... I only went to isomerization, cause from what I've read acetylation didn't have the intended effects b/c thc is so lipophylic. It has an affinity to leave the blood stream and enter fat cells. This is also why medibles work so well though... and really that's that best form of ingestion. I like to make butter with my extracts, and put it into a 00 capsule. I have to ask though, why salt water? I used RO water.

When the water is saturated, it is unable to pickup other water solubles, except for the alcohol. They get left behind on the sides of the flask and in the sludge.

The point of the water filtration with the separatory funnel is to remove the water solubles, like chlorophyl, and anything else that might contaminate the final product. At least those were the instructions I followed. When you add the sodium bicarbonate to neutralize the acidic solution, the bicarbonate is cleaved and released as CO2, leaving behind the sodium... So the water is supposed to pick up anything that remains.

Anyway, that's my reason for asking... Thanks again for sharing.

Good topic brother BH! As you may note, our process is different enough to not involve neutralizing with sodium bicarbonate.

As the lowly ancient equipment and process engineer in our scraggly group, I am going to encourage our bio-chemistry student, whom developed the process, to take a momentary break from class and adoration of his first new born son, to join this forum and provide the intimate details that you seek.

May I get back to you with his thoughts?
