I tried making some hemp oil, for medicinal reasons, using acetone as the solvent. I let the marijuana sit in the acetone for two days, strained the marijuana out and let the oil evaporate, using a heating plate.

I am basically hoping to use rick simpsons method for the next batch but only have the option of acetone for the solvent.

The yield was huge and looks like typical hash oil, but psychoactively i think it might be quite weak. any ideas what went wrong?

I like using acetone for making oil as it evaporates very well by itself (in the sun). I would say you soaked it too long. I run a batch off after only 5-10 minutes of shaking and soaking. You can run another batch off after the initial one which obviously will be weaker than the first, but the 1st one will kick ass.

You said "hemp" oil. Does that mean it was hemp that you extracted, not normal potent plants? If so, you need to isomerize it by heating in a solvent (like acetone) with a few drops of sulfuric acid in it (which you can buy as a drain cleaner, brownish liquid). Then you neutralize the acid with soda, which stays on the bottom. Of course, you'd have to be careful heating a solvent, especially acetone. Make sure you have a cover handy. Actually, you shouldn't even need to heat it, just let it sit for 24 hours or so at room temp. The heat would only speed it up.

Well, I've never used acid or soda and mine came out perfect and potent every time. Been doing it that way for over 30 years and it works fine. The only heat that I may give it (if the suns not shinning) is from a hair dryer. Anyway, mine works good for me and yours works good for you, so it's all good huh? Oh, no I don't mean hemp oil, I mean weed oil.

I meant if the oil was weak because it was from weak weed then isomerizing would improve it. You said it wasn't very psychoactive. Obviously, you wouldn't isomerize oil from good weed.

Please explain the process of "Isomerizing", in layman's terms.

I am very interested in how this process is done. I remember back in the late 70's, there was a machine that could be purchased to make Hash and weed oil, called the "Isomerizer". It sold for about $500.00 if I remember correctly and was about 3 feet tall. A really wierd looking thing(which was most likely a marketing gimmick), but the thing made real good oil.

I am just curious as to the process, we know how to, or there is instuctions on how to do everything from "Honey Oil" to "Bubble Hash". I think a "How To" on "Isomerizing" would add to the collection of this type of information.

If it's possible...Step by Step.

Please and Thank You.
Peace...Buddhasmiletoke

The Isomerizer, aKA ISO II was actually a very illegal distillation device. One would put your 'substance" in the special container, turn on the 100 watt specialized light bulb, and add your ISOPROPYL alcohol.

The alcohol would evaporate and continually cool in the top of the device, then run down through the substance as liquid. The oils would collect in the warming pan for later removal.

You could also use this device to take shitty wine and make it into brandy.

Boy, that brings back memories. I can still vision the thing sitting on the table.
I can try and explain how it worked but it's been some years since I had it. It looked like a giant bullet about 24" tall. There was like 3 sections to it. The top section was a clear spherical like bubble. You put ice in that section. The middle section was a reservoirs for whatever thinning agent you were using EG, naptha, acetone etc. Inside the res was a perforated basket that you put your raw materials in.
It worked something like this....The ice dome in the top would attract the thinning agent in droplets. The droplets would then run down to the bottom of the dome and drip off into the basket and through the raw product. After a few hrs, you would take your fine brew and set it on an electric hotplate to evaporate the residue.
It worked on the same principal as a coffee maker, only without using electricity (for the brewing part). High Times used to sell them for making "perfume" and were quite legal to buy. I did a quick google search for a pic but could not find one.

...Added...
After doing a little more snooping around, there were other versions of this contraption as well. The one I had was mid 70's. Heres a link to a different version... CLICK

With isomerizing you can change cannabidiol, which is plentiful in hemp type plants, into THC. You simply add a few drops of sulfuric acid to the oil solution before you evaporate it. You heat it gently for an hour or so but I think it would work at room temp if you leave it sit for about a day. You have to neutralize the acid with something afterward of course, so you don't smoke sulfuric acid. You wouldn't isomerize weed that's already potent though because it also converts any delta 9 THC that's present into delt 6 THC, which is only half as potent. So unless it's mostly cannabidiol, you lose potency instead of increasing it. No strain you would buy seeds of would be mostly cannabidiol. Isomerizing comes in handy if you find a field of wild hemp though.

Don't ever use an isomerizer. Its very dangerous, and can start fires very easily.

Acetone is a water soluble solvent like isopropanol. The longer you let the pot sit in it the more water soluble constituents of the pot will become part of your finished product thus diluting it. And making it taste nasty.

After making such a product it can be greatly improved by doing a simple separation with a solvent like naptha/pet ether etc. Solvents like that are not miscible with water and the oil will migrate into it while the water soluble bits will stay in the ISO or acetone.

In Rick Simpsons simple recipe he uses ISO as an example as it it easy for the non-technical and easily obtained. He also only has the ground bud in contact for a few minutes with a quick wash. This dissolves the glands without leaching out the chlorophyll, waxes and other crap you don't want in a high quality oil that you may need to use to save your life.

Solvents purchased at the local paint store etc should not be used for making oil for human consumption. They are industrial grade and can have any number of contaminants in them that will be left in the oil after evaporation.

They can be purified through distillation if you know how not to blow yourself up. My fave is Coleman camp stove fuel. Distilled it produces a pure, light naptha with a boiling point of 71 - 78C. All the nasty stuff can be tossed out. Other brand use a heavier base solvent that boils from 90- 95C. Not worth using.

If you can't get ISO you would be better off using 99% methyl hydrate aka methanol, methyl alcohol. wood alcohol.

Use it straight from the freezer and only wash for a couple of minutes tops. Then a very quick rinse to get the last of the goody.

Have fun, be safe! pass

peace
