TEK - Green dragon question

[Herbal Healer 019]

SWIM just made some green dragon using 5 grams of high grade (most likely sativa) bud.

SWIM ussually heats the bud on 250 for 10-15 minutes prior to placing it in with the alcohol (151 proof this time). SWIM wasn't thinking clearly and poured some alcohol in with the cannabis, .5 oz or less, but decided to heat the bud anyways with the alcohol already present. SWIM placed it in the oven on 250 F for 15-20 minutes and found the alcohol to be bubbling when he took the bud out of the oven. SWIM immediately added the rest of the alcohol, 1.5-2 fl oz, into the jar containing the bud & it immediately turned dark green upon stirring.

SWIM is worried, that because the bud was left in the oven on 250 F for 15-20 minutes & discovered the alcohol to be boiling at the time of removal from the oven, some of the cannabinoid content (thc, etc..) will be decreased possibly due to too high temperature caused by the boiling alcohol. Does any1 think this will significantly affect the efficiency of the cannabinoid extraction in a negative way?

if the alcohol boiled it prlly destroyed the alcohol content and yea soem of the cannibinoids prolly vaporized.. but there is only one way to make sure...

alcohol boils at 72 degrees celsius, about 162 degrees farenheit, and the oven was on 250 degrees farenheit. SWIM beleives cannabinoids are vaporized at or above 350 degrees farenheit. So SWIM is hoping that the boiling alcohol did not destroy any cannabinoids. Cold alcohol was added after being taken out & noticed the alcohol turning from clear to dark green, obviously cannabinoids were being extracted into alcohol, IDK how much cannabinoids, if any were lost. But I guess SWIM will never really know and hopes for the best, otherwise 5 gs of chronic were wasted.

well the green could jsut hbe the natural dyes of the herb, but i mean i have a feeling swiy will find out soon enough.

Well when people make cannabutter, dont they boil it?

[tryptamaster]

i mean swim has made cannabutter for cookies and brownies and he doesnt really boil it. jsut meltds the butter so its hot to the touch.

[gmeziscool2354]

the deal with evap is that if the temperature of the solution boiling is lower than the triple point (vapoization) of the substance dissolved in it, than it will simply boil off, leaving all of the dissolved substance behind.

based on prior posts, even though the ethanol boiled, one would not believe that any active material was lost. THC is solid at room temperature, so its triple point should be quite high, as opposed to ethanol and water (two main solvents in 151 rum) which are liquid at room temp.

remember for virtually every substance, Solid has the least energy, followed by liquid followed by gas.

Thanks for the more definitive answer.

Let's get metaphysical for a second.

Everything breaks down. Water molecules, THC, the plan matter, a pipe, a lighter, you, the chair your sitting on, and the world you live in. One day, all of it will end up as individual atoms floating aimlessly in space. Entropy will be maxed out.

Now let's get real - but not too real.

Even at room temperature, THC breaks down and marijuana buds loose their potency. Especially with air exchange, heat, or light. When the THC was heated in the alcohol, bubbling and all, some of it broke down. To my understanding, boiling point is the maximum temperature individual molecules of a substance can achieve without necessarily breaking down.

When marijuana is heated in a lipid, most of the THC is trapped in it and it doesn't evaporate. Mixing butter, oil, or alcohol with marijuana brings out the THC and other non-polar molecules from the organic plant matter, which in turn would be polar and soluble in water. Your alcohol so called 'saved' the bud, held onto the THC, and kept it from blowing away.

But wait, alcohol evaporates at 78 C , and the oven was at 250 F? The alcohol was bubbling away, and could have been taking the THC with it.... .even though THC vaporizes at 200 °C (392 °F) [473.15 °K].

And it did turn green, while clean ideal extractions are of a different color.

Second individual:

What he means to say, is that we really don't know what percentage of THC remains in the bud. Statistically, 5g of average potency (dry) bud, even at 10% THC per gram would contain 500 mg THC, this would undoubtedly get an individual high. (All assuming none is lost)

What SWIY made could be consumed, and should it be, post a report on how effective it was. Make a test out of it, lets learn something about the loss in THC due to evaporation in an alcohol solution.

First individual individual:

*Yammer's on about colors and extractions...*

Second individual:

See, this is all just a story.

Entertaining post, lol

SWIM is aware that the "ideal" tincture is amber colored and not dark green (all the terpines have been extracted; some ppl dont want the terpines), but SWIM personally likes to capture the essence, if u will, of the buds; terpines and all. SWIM would even say that a tincture with terpines & the excess plant oil is probably even more potent than one not allowed to absorb all the plant matter, the reason being that there are many different cannabinoids present in cannabis other than thc, which can significantly add to the high.

SWIM will report back on the effectiveness of the tincture in progress compared to some "mid-grade" sativa tincture, which was surprisingly potent, at the end of this weekend

...Also, SWIM was wondering since the cannabis & the alcohol were in a small spice container (glass), is it possible that the glass, which is a good conductor of heat, caused the alcohol & bud to go over 250 degrees farenheit?

Uh.... no. Think about what you're asking for a second.

If the oven was set to 250 degrees, the maximum temperature inside it would be 250 degrees, unless something was producing more heat inside the oven.

Glass is a poor conductor to begin with (countless labs with shitty Bunsen burners I've tried to boil water and it takes ages), and it could not add any heat anyway.

(And I'm quite sure about this one, this time)
