Saturated solvent?

[WhoaManThatWasIntense]

Hi fellow explorers,

If my cat's solvent remains cloudy (like how a freeze precipitate goes) at room temperature, is the solution saturated? It's been used on two extractions so far. Will it get more concentrated the more times it's used in different extractions?

Thanks,

Sounds super-saturated to me.

Stick that thing in the freezer.

I got some sort of ice-DMT sludge that was more ice than DMT from one container, got quite a nice amount from the other one. It seems like it takes longer to precipitate out each time I reuse the solvent, but I could be imagining it. Maybe i'm getting some condensation freezing on the side of the jar or something like that, does it seem likely? I would have thought any water would have collected at the bottom at room temps, which is what seemed to happen the first time round. Just a thought I just had, could I need even colder temps than my freezer can provide the more it becomes saturated? Doesn't seem likely but i'm no chemist.

It is probably oils that are causing this. After my naphtha turns really yellow I usually evap it all down and use fresh naphtha.

Water in the jar would be seen at room temperature. The more saturated the solvent is the less cold it needs to be to form a precipitate.
