Winterize in Butane using Dry Ice?

Question for the masters out there: Would it be possible to avoid introducing a second solvent by using dry ice to winterize a butane extraction prior to purging any butane? Straining the soilds might be even easier at these temps.

Thanks in advance!

No...
You can use chilled tane to lessen the extraction in the first place..sort of.... but dont "winterize" in it...remember how winterizing works..reducing the temps of a non polar solvent will drop out the polar constituents, the psychoactive components.....

Why does this come up so often? As it theoretically won't work its not a natural conclusion to end up at, so why do so many ask about this and where does the idea come from?

single solvent dewax works for me, I just blast straight into a beaker pre chilled butane and keep it below -20c the whole time. A 20% yield becomes 10% after dewax

I may be misreading but are you saying you are losing half your yield?

I don't really do pics......so check out what guz got after winterizing...waxes and crap looks like crap, usually bright electric in color whether yellow or slightly green...
1st poster..why is your wax white?
Why is the finished product after winterizing not shatter?
Then if you can answer that...tell me how.. all scientific like...this works, its like adding acid to salt and saying you did an a/b

Yep.
7g in , 1.4g out, after dewax 0.7g

I tried dabbing the wax to see if I was losing anything valuable, and it's hard to say but there might be some terpene loss, depending on temp and time used.

Because wax is colorless, the colors you mention come from other things such as chlorophyll etc, things that get extracted when you soak the flowers too long.
The finished product is not shatter , because why does it need to be. A high CBD oil is never solid at room temp for example. The temperature used for the purge will be a decide the final form, slightly decarbed oil will be thinner.

That seems like a very steep loss. I winterize with ethanol and do not have near a 50% loss. 9grams bho in usually ends up between 7.8-8.1 grams shatter out.

The end result requires me to take a dab half the size to get the same result. Amount of wax is going to be dependent on various factors like indoor or outdoor, strain and other things. And I still love my oil non dewaxed as well, I just wanted to try the single solvent dewax method to see.

They aren't white....
Why does it need to be? That's what happens after you winterize.. a polar wash leaves shatter because the compounds are solid at room temp..high cbd is also shatter at room temp with a melting point around 145° most will say indica produces more shatter anyway though being higher in sesquiterpenes and less wet/sticky components...the temp used for the purge does determine the finished product and since you don't have beautiful wax or shatter are you saying its liquidy because you decarbed it? I would believe that..it looks just like some peoples decarbed rso...might change your purge methods unless for edibles
So you cant say how this works just that it does? And it results in wax that doesn't look like it should...or like anyone else's?
OK well that's cool for you I guess...now if the rest of us could defy physics(I think that's right)...
Oh and I'm not being mean! Welcome to the forums

I'm a little confused. I just showed a picture of epicuticular plant waxes that have precipitated out of my butane oil solution due to extreme cold temperatures, slightly different than traditional winterization non polar to polar solvent.
Changing my purge method for what reason, If i wanted to use lower temps to retain the oil in a carboxylic acid shatter I could have. Did you consider I might want to make odorless hash oil e-liquid, if I did this would work great.

Well if you recall my first statement.....how do you propose a compound with better solubility will precipitate out a solution before a compound that is less soluble..this is the basis behind the polar/non polar wash.. lowering temps of a non polar solvent will drop the polar compounds.. this shouldn't be to confusing for you..
Now this hasn't been discussed much but because of these compounds melting points they are a solid at room temp when relatively pure...decarbed hash can still produce shatter and wax.I have shatter pipe resin lol...hasn't really been brought up because when making wax they can get goo and it confuses people.....anyway...
Winterizing works just like an a/b extraction...like I said throwing acid on salt won't cut it
now why would you say you wanted odorless hash for ecig when you just mentioned nail dabs...if you weren't going for the most pristine and potent product then carry on

Maybe posting about dewaxing in a winterizing thread is confusing, since winterizing is using polar to non polar solvent and dewax is single non polar solvent.
To further prove your point, I just took a fat dab of the pure wax while totally sober and I definitely do feel something. I recall a mention that you can lose monoterpenes some of which are psychoactive, depending on time and temp used. Of course I'm going for the most pristine and potent product, but if I happen to mess up the purge and use too much heat I have other uses. Personally I prefer something slightly more malleable than shatter, but it seems like the opinion is that if it's not shatter it don't matter?

My bad. Not winterizing. Dewaxing. So it can be done.

I wonder, if you dewax, purge butane and then winterize in ethanol would you get even more 'wax' precipitation? Would this provide a more pure absolute?

If nothing else, dewaxing in butane would save money (dry ice is cheaper than 190) and you don't have to wait 48 hours and then deal with a ethanol purge.

Sorry I am not a chemist or I might have more scientific terminology.

None of the c&e contributors have ever dewaxed........

Hey guys If someone would test the white stuff left settled at the bottom by a lab this would quickly answer the questions as to what it is exactly and how much thc, cbd etc..are in it.

I have tried the stuff I have left over like that and it's potent so I don't try to get it out.

I have seen guys on youtube saying they take all of that stuff out of their solvent/oil extract thinking that it's wax and I just don't buy it. If it was pure plant waxes why does it get you ripped?

Or with a little prep work and some skill you can get a pristine 10% right out of the gate without having to remove a bunch of lipids at the end. (on trim)

Fresh, frozen with controlled solvent use works well. Even if you did winterize you would see very little accumulation.

Never tried that, but have extracted using a -70C cooling bath for the butane before injection, so as to not extract the waxes in the first place.

Another thought, and that is if you had two chambers, with a filter between them, you could chill the butane with the oil in it to cryogenic temperatures in the first, and blow or push/pull it through the filters into the second chamber, where the butane could be recovered using vacuum, leaving the de-waxed concentrate behind.

Hey so I dewaxed by accident. I did a run outside in -10C and left the glass dish outside waiting for it to evap without any added heat and it did take a few hours but there was a big disc of wax floating in there. Had no idea what was going on. Can anyone confirm that this is possible? I'm actually upset that it happened because now it wont shatter up in the vacuum purge.

Yes, the waxes will precipitate out of the LPG at subzero temperatures and is the principle that inline dewaxing relies on.
