making ethanol oil

Hey guys, great thread! 

 

I'm going to try an ethanol extraction of a high CBD strain (Dinafem CBD Plus... 15-20% CBD / >1% THC). I will use the Jeff Ditchfield method of washing the (frozen?) buds with ethanol from the freezer, filtering through a coffee filter, then a home water distiller, then finally using a magnetic plate and stirrer to decarb and evaporate the remaining ethanol. Seems like a good method?

 

Has anyone tried this? What percentage of CBD can I expect from the finished oil? Does CBD have a higher temp at which it decarbs than THC (110 degrees)? 

 

 

yes mate as stated in PM

 

just the decarbolization needs to be tweeked in a bit -takes longer than THC and its harder to know when those CO2 bubbles are all gone, that's why I had such high CBDA levels (39%)

thanks Joba... would you say you under cooked it to get CBDA? I guess thats the natural form i.e. THCA decarbs to THC.

 

please could you tell me more about your methods so I can modify mine before my first ethanol run?

when I will be doing CBD oil again once I am finished I will decarbolize probably under magnifing glass to see if all the small co2 bubbles are gone

also will do extraction from bigger badge maybe 4oz not like last time only from 1 oz- this will allow extra time to decarbolize (while still evaporating in slow cooker)

Thanks Joba 

 

do you find a slow cooker adequate to decarb and reduce to oil as a final step? I’m looking at buying a magnetic hot plate stirrer

i am decarbing while the slow cooker is evaporating ethanol but the final stage I do over a bowl with hot water -boiling water at 100C and watching the CO2 'bubles':yinyang:

once they stop forming I am done,put my oil in silicon container and make tincture or sweets

take it easy on feed as even when cuttings they well fragile,last night i took 2 perfectly rooted clones from a sandwich bag and within 1hour at room temperature all leafs schriveled.

Just a thought - if you are burning off ethanol at 80 but THC De-carbs at 110, then you can’t do both at once?

Just done my first ethanol extraction. Went well. I did a frozen quick wash of three minutes and a second wash of 11 minutes (room temp). What I found was that the quick wash didn’t produce enough oil from my half ounce so I had to combine it with the second wash to get it into a 2gram syringe. 

It was very strong. Licked the bowl as I cleaned up and I’ve only just woken up, the extraction was Sunday night!

I think you can do both at once,even drying bud is form of decarbolization/oxydation just at much lower temperatures and longer time

Time and temperature.  Cannabis decarboxylates at room temperature, it just takes longer.  The same heat that decarboxylates, also converts THC to CBD, so the speed that you do it at, determines how much THCA is both converted and how much THC is left.

You will have more THC left, if you decarboxylate faster at 122C/250F to 144C/292F.

Thanks Greywolf. This makes sense as I turned up the hot plate way too high because the liquid wouldn’t get above 70c. I now realise that this was because of the ethanol still being present. As soon as the last of the ethanol evaporated the remaining liquid got very hot very quickly. I took it off the heat and although it bubbled up, I don’t that it spoiled. It was a very thick liquid that  had stuck to the beaker sides where I had tried to increase the surface area, in order to not overheat it. I added a little more ethanol to help scrape it off the sides and started to cook it down again, this temp at a more stable temperature. Patience is key! CBD wash is next up. I’ll keep the temps at 110c but I’ll cook it for longer and wash for longer as it’s for ingestion.

A quick question if I may good sir?

 

If I'm planning to make e-juice using bho as my starting material which of the VG/PG mixes work best?

60/40,80/20,50/50??

Or does all VG/all PG work better??

 

I know your not an advocate of using them yourself but your answer will nonetheless be appreciated.

 

Many thanks

Can I piggy back on this question and ask if it’s possible (or advisable) to make vape juice from ethanol extracted oil?

Solly, because I don't support using a diluent for e-pens, I haven't personally experimented  beyond our initial trials, so I will plead ignorance on your first question.

 

As to your second question, yes you can use ethanol extracted concentrate in an e-pen, and it works well.  QWET or subzero extraction works best, to avoid the chlorophyll, et al. 

 

Some cart manufacturers use ethanol, and loosen the concentrate up by adding back monoterpenes, which also act as a diluent.

 

You can even leave a minute amount of ethanol in the concentrate, to add a slightly sweet background flavor and loosen the concentrate up enough to flow, without using VG/PG/PEG/triethyl citrate, or long chain alkanes to dilute it.
