Dry Ice Winterizing

Ok sorry I did not mean to imply that the product created with dry ice temp butane is the same as a winterized absolute. I just want to understand why using super cold butane has a difference on the consistency (more brittle) of my final product when all the science says that it should not.

Because freezing decreases the rates it extracts as well as reducing impurities of the polar and heavier non polar kind....., you could equate it to a frozen qwiso vs room temp.. stopping the absorption of nasties.....by no means takes the place of a winterization

Call it London forces or just plain van der waals ..butane absorbs 61 mg per liter of water allowing for impurities besides just wax to come over...hexane with 6 carbons is basically the point water is no longer soluble at all giving the cleanest extract imo...but freezing stops it from absorbing those polar impurities and will lower its ability to absorb and hold heavier non polar compounds, slowing extraction rates

Lowering the temperature of a solvent slows the dissolution.
At a temperature of -20C, it takes about two hours to wash ~90%.
The temperature of dry ice is so low that more or less complete extraction would require a very long soak.
It seems to me that it would create a significant disadvantage?

Well if a graph was made it must be true...judging by the black green goop after the 45 minute wash above it, I have my doubts...I wonder how it was kept a liquid for so long(ah the freezer I missed that), I didn't see anything about it just a graph..no explanations or even how the conclusions were made....but whatever

Dark goop is the residual resin extracted from the ground and decarboxylated material remaining after the main two-hour extraction.
For a more detailed explanation, try to start reading a little higher from the post#292, and even better from the first page.

i do not think freezing the butane makes the consistency change, but the rate that the cold butane runs over cold material and is more prone to soak on cold material then warm. i actually am swiitching back to useing room temp cans and making sure i am using frozen material, usually stick my tubes in the freezer after i pack them.

You are right, the dissolution is very slow. I performed my usual extraction with the only difference being the cold butane and my extraction rate fell from 14% to 5%.

Ah I forgot to mention some important details... When collecting the super chilled butane with dissolved oil, there is a layer of sticky stuff on the bottom of the collection vessel which I suspect is the waxes stuck to each other. I did not collect that stuff, which I think is the reason why the final BHO had brittle consistency.

Just to clarify, are you saying that a soak is more likely to be achieved when pre-freezing plant matter in columns? I was feeling lazy to do this because I figured running super cold butane through the column will achieve the same effect. Looks like I have to invest in more columns...

That is why the flow column is not an optimal instrument for pre-cooled butane, it can not provide long-term contact of the material with a solvent.

i like freezing my cans...

i like insulating my tube...

when i used to run room temp cans, non wrapped tubes.. my butane would never make it so far... why?? maybe i had a leak out the top.. i dont remember, been spraying cold shit so long i forgot.. it seems everytime i use chilled tane, along with wrapped tube, i can use less butane...

i tried the room temp can thing the other day and had to use twice as many cans as usual ... soo pissed..

Ahhhh...

I had a feeling...

Very very nice to have you around sir...
Much much much respect...

Not sure of you have seen, but I've credited yourself, Gray Wolf and Gunna Know with pretty much everything I've learned in this capacity...
Thank you!

Hashhaha..
I did...
EDIT I knew FD was GW from the moment I read one of his posts and linked that to his avatar, I did not reveal his identity on the boards, I did however tell a couple of people through pm's .

I believe VP was actually the one who asked him directly on the boards.

Just wanted to clarify that.

Also...I knew MiG pilot was Jump the moment I read his first post, linked the name through following his posts.

These two gentlemen are my inspiration. I've learned sooooo much knowledge simply by following their posts.
Also..the two most humble genius level cannaseurs, on the web.

the waxes will dissolve in the butane even at those low temps, have you ever measured the temp of the butane coming out of the can? i just did it was -15 when i took the pic it was -11, go check your freezer mine set on high barely gets to -9, and for all the stuff to fall out it needs to be placed in sub zero temps for 24 to 48 hours

its the fact that the butane is what type of solvent and the alcohol is another type.
one is more prone to extracting waxes fats a lipids where the other one is more prone to dissolving chlorophyll, why you will see green iso
