As a quick addendum, I am finding that with extremely dirty isopropyl the resin will clump up into tiny blobs during heating and boiling. This makes for easier cleanup and it kinda looks cool.
I am wondering if I can leverage this as an intermediate cleaning step between full distillations. While putting containers of contaminated isopropyl in the sun for a few days may have a similar effect, it wouldn’t hurt to try and speed that process up.
The garage door is open, the cars are pulled out and I have a disaster plan. (If I drop a beaker or spill a significant quantity and it ignites, I have 50lbs of sand right next to me as well as a fire extinguisher. CO2 is the more effective option here.)
Vapor loss is minimal as the glass joints are sealed and clamped. The cool-side vapor loss is negligible. I may put the collection glass in an ice bath to further minimize vapor loss.
Also, I am no stranger to hazardous environments. Moving around this stuff is with purpose and any actions are thought out. (FWIW, I am a trained firefighter, but that was from the Navy, many moons ago.)
Regardless, there is risk. I can’t stress that enough.
(Gor other readers, I am not arguing the safety points with any of this stuff. There is risk with everything about this process. Period. Understanding the properties of other chemicals is super important my comments are an addendum, not an argument.)
Not too worried about the BPA as the IPA boiling point is way too low. (At my altitude, the temperature is holding at ~84C.)
The acrylates are a bit nastier, but something to think more about. I’ll need to dig into why the resin is clumping at temperature, as that is probably the acrylates doing something special.
Still, this is extremely diluted solution until the last bits and don’t evaporate all the IPA so the resin doesn’t get cooked. (Working in a reasonable temperature range does mitigate some of the nastiness.)

This is legit cool, but the fact that you’re doing this on a garage floor instead of in a hood or outside is terrifying

These companies barely release data sheets for pla filaments. I wouldn’t boil anything with resin in it in any garage for any amount of money.

Brother, I hope you’re in one of those Andromeda Strain full body suits.
