下载A lot more depends on fossil fuels than you might expect.
Like your medicine cabinet. No, not the plastic pill bottles… the pills themselves might be derived from crude oil.
Indeed, one of our most commonly-used drugs uses a component of crude oil as a starting material.
And that drug is: Tylenol! Which is, by the way, safe and effective, including during pregnancy.
Hence why it’s commonly-used. More than 15,000 metric tons are produced globally every year.
Which means a lot of petroleum goes into that needed, safe and effective pain relief.
Unless we didn’t have to use oil.. It is possible to recycle plastic and turn it into Tylenol.
Not possible for us humans, though – we need a hand from a pretty unexpected place.
[♪ INTRO]
Crude oil contains the starting chemicals needed for a bunch of things you might not think of, from shaving cream to paintbrushes, clothing to fertilizers… and acetaminophen.
AKA Tylenol. Also called paracetamol outside the US.
We’ll just stick to calling it Tylenol for this video, though keep in mind we mean the substance, not the brand..
See, Tylenol is made up of carbon, nitrogen, oxygen and hydrogen.
But the thing about chemical synthesis is that you can’t just pick out the elements you want and stick them together like building bricks.
There are only certain chemical reactions that are physically possible.
To build up a molecule with an oxygen here and a nitrogen there, you need the right conditions to achieve those reactions.
