Chemistry of Nicotine

According to the info that you have provided, the nicotine can reach and withstand 477 degrees ferinheight before breaking down. I'm not sure how hot the nichrome gets with in the atty, but my assumption is that a majority of the vapor is produced long before the nichrome could ever reach that temperature.

The fact that the nicotine is slightly water soluble, leads me to believe that much of it is carried by the vapor, maybe more so than a cigarette, since there is no filtration in our ecig and we lack the surface area of a burning cherry, which has reports of 1700 degrees fahrenheit, that would definitely destroy any remaining nicotine that hasn't been carried by ash particles.

Essentially, we already are free basing.

Perhaps; we just don't know for sure.

But people, and some studies, show that the absorbtion is both slow and low when vaping.

My possible explanation for this is that VG / PG (VG in particular) dissolves the nicotine and it is held by the VG in droplets; VG is extremely reluctant to evaporate; not sure about skin/lung absorption.

Came across a new source today on the chemistry of nicotine.

I was primarily interested in the possibilities for synthesis, but there are some other interesting things on this site.

Worryingly, the author states quite boldly that nicotine is a carcinogen in it's own right, through a mechanism that can create a strong radical.

Water is explosive in it's own right through a mechanism that can liberate free hydrogen.

My point being, unless the author can show that the mechanism is actually significantly present in smoking related activities, it isn't going to create the radical, and thus his assertion may become a practical non-starter.

Oh.. on your comment earlier in the thread on folks vaping at 6 volts getting a sharp, burning taste.. I never ever want to vape VG at 6 volts. They're quite possibly describing acrolein.
