Allow me to show my ignorance on the subject and ask if am I misunderstanding what you’re saying. You want intentionally heat the guaiacol to the point that it is smoking? What’s the reasoning behind this? I’m not a chemist, but I am a firefighter, and I know that when liquids start producing smoke it’s usually a bad thing, like 99% of the time. What’s different about guaiacol?
This is not a chemist talking, just a guy.
Nothing different with guaiacol. The difference is in the var. It was not made to be in oil.
But I probably should've said "just before it smokes", like you add heat until it smokes and go back and forth for a little while, so there's some smoke, but not smoking the entire time...
The very high temperature will ensure the fusion (probably not the right word) between a powder that doesn't want to be there and its solvent. And your carrier should be hot too at this point or it may want to crash.
I should've add that you swirl while heating too, but if you cook, you know...
