Naphtha mixed with Heptane

[CokFLHX]

I accidentally mixed naphtha with heptane, and have no idea like what percentage is which.

They are both non polar solvents. Can I still use the resulting mixture just like I would if it were all heptane or all naphtha for extracting?

Yes, it's fine. Heptane is essentially a component of naphtha.

Shame about the heptane, though.

What I usually do, when my solvent has gone from clear, to a yellow or orangeish color, is run it through a distillation. It clears it up and makes it like new.

I think I can perform a fractional distillation to separate the heptsne next time

You can do a sodium carbonate or a brine wash instead.

Best of luck, hope you've got a decent column. If you really want to separate n-heptane from the 97-99°C fraction you might have to co-crystallise it with urea (iirc).

have a ton of gooey stuff so now i just warm up some heptane and slurp the top layer off then freeze it?

You're going to have to be a lot more specific than that with your description. What goo where and how did it get there? Are you extracting, or are you hoping to attempt a recrystallisation?
