It’s a very realistic comparison.
McNugget terps.
Which terpenes specifically boil at less than 78 C?
From Encyclopedia Britannica:
The monoterpenes are isolated from their natural sources by distillation of the plant matter with steam. They are volatile oils, less dense than water, and have normal boiling points in the range of 150 to 185 °C (300 to 365 °F).
I’m thinking maybe it’s going to be more about vapor pressure at given temps… time to dig!
Linalool is coming in at 198 C, pinene at 155 C… it does make sense they would have a higher boiling point than alcohol since alcohol is only a c2 while even monoterpenes are c10.

78c and at -30hg???
Lots of terps

This is another internet quote:
For example, ethanol at atmospheric pressure (760 mmHg) has a boiling point of ~78°C, and at a vacuum pressure of 100 mmHg ethanol has a boiling point of 31.5°C.
End qoute.
All compounds reduce in boiling point when you apply vacuum. I’m still inclined to think this is going to be more about vapor pressure at given temperatures.
So ethanol has a vapor pressure of 59mmHg at 25°C.
Pinene has 4.75mmHg and limonene 1.55… going down as we get into more complex terpenes it seems like.
But things codistill because even if they aren’t miscible as liquids they can share the same vapor stream, headspace, whatever. I also know the vapor pressure of a solution is like a shared vapor pressure.
So I do still need to do more research, but I think it goes something like you have like 40:1 in the vapor stream of ethanol and limonene if they were the only 2 present… which obviously isn’t the case here, but that’s my short of the concept as I currently understand it.
It seems like a tiny amount of terpenes at that ratio you’d be losing, but if they only make up a small percentage of the solution and the ethanol makes up a massive percentage of the solution before you reach the end you’ve probably removed them all.
Also keep in mind for comparison that ratio when compared with butane which has a vapor pressure at 25°C of 1820mmHg the ratio for that recovery is like 1100:1… again if I’m understanding how it all works correctly.

…ethanol? Eww.
Not really fair to call it eho when you use butane first

Ya if the end quality of this is good then I feel like it is despite is touching ethanol not because of the ethanol. Seems like the ethanol is gonna pick up a bunch of water getting passed over live material.

Indeed.
My point was that if you understand pressure/boiling point curves, you can remove a lot more ethanol than terpenes when your parameters are dialed in. If we can remove water from live resin runs while keeping most of the terpenes, even milder parameters will remove ethanol as well.
Of course you won’t keep ALL the terps, with azeotropes forming etc.

So basically, you’re trying to reach and maintain total saturation of the ethanol? Maybe it picks up more terps when the etho is at the total saturation point of the cannabinoids? I’ve only done a handful of etho extractions, but this is something that I have read that both here and on other sites. The washing of whole bud with the same solvent used for a previous extraction leading to an overall better tasting extract. I think it might have been on FB in one of the extractcraft’s groups for the source, and etoh pro
If you guys buy me a gallon of ethanol I’ll try it out and give out free samples to anyone who wants to try on the west coast

I’ll throw $20 bucks towards a gallon!
Ends up being an eho.
