Running ethanol currently
I have to order it online and the only thing I see is from USA labs and is denatured with n hexane. Will this run the same maybe a little faster with hexane ?
What are you using the ethanol for? Extraction?
Sorry yes flashing, distillate end product
should you be able to distill the hexane off? hexane boils 18 degrees lower than ethanol.
Will that make it more unstable?
No. why would it make it more unstable?

molecules? I’m lost on that statement please elaborate on what you think would happen to the respective molecules.

what would be the point of a trivially removable denaturant? (asking for a friend).
(it is and SDA formulation, not a CDA formulation, but yet…)
I would think that the Hexane would grab fats even at “cryo” temps. I’m making an assumption that it could be fractionally distilled off due to the boiling point difference but theres alot about chemistry that I dont know. Can it be distilled off?
most of the stuff i see is denatured with N-Heptane which would be considerably harder to remove.
I think the point is that it can’t be trivially distilled off.
looks like hexane can be used instead of heptane or toluene in CDA-12A (https://greenfield.com/wp-content/uploads/2018/11/CDA-12A-2-200-Proof.pdf)
I would assume formulations listed as CDA (completely denatured alcohol) would not be trivial to “renature”.
although I think I recall reading some EU denaturant rules that suggested they just need enough of the denaturant to stick around so they can bust you for tax evasion by showing trace denaturants.
@Shortpath are you recovering none of your solvent?!?
N hexane is cooked off faster than ethanol. Hexane picks up less trash but it’s unstable. Ethanol is slower but extremely predictable in my opinion. So wondering if the mixture is stable. No clue what denatured even means
I assume that the Hexane would remain stable while mixed at that low of a percentage with ethanol. someone said on here that it would take on the same properties as the ethanol. I process with N-Hexane all day and haven’t had any issues but my systems are closed loop so I’m not as concerned about the vapor pressure difference as I am about the fact that its a non conductive fluid. Denatured essentially just means you cant drink it.
Are you using a Buchner and filtering it ?
still not clear what you mean by “unstable”.
denatured alcohol means some bugger put poison in there to stop you drinking it (its no longer “natural”). the denaturant is specifically chosen to be difficult to separate. because otherwise you won’t pay the sin tax associated with potable ethanol.
