Converting Corn Cobs to Furfural: Organic Chemistry
Вставка
- Опубліковано 19 чер 2024
- It's corn! Corn is a staple of our diet and has been for hundreds of years. It is the second most grown crop, loved by many, and most likely, you will eat a corn product today. After the corn kernels are taken off the cob, we are left with a pile of seemingly useless corn cobs, or are they? It may seem impossible, but we can do chemistry with these discarded cobs and get a pretty fascinating compound, furfural from corn cobs.

Thanks for watching!
For furfural applications, you could either transform it into THF which is a great solvent to have around if you want to do Grignard reactions, or reduce it into furfuryl alcohol if you're into rocket science.
Liked the clip. I recall that in Freshman Chemistry, going way, way back, it was explained that it was this chemical reaction that made much of Chicago. Boggle, did not anticipate that one. I had thought that Chicago had prospered because it was a significant port on the Great Lakes. Then, later, someone else, a different Prof, claimed that it was 'white metals' (tin-based metal alloys) that made Chicago, Chicago. The point being, I gathered, that Chemistry can be a real money maker. Heck, I already knew that. And now, so do you.
Yeah, chemistry is a very good money maker due to the importance of all the products that can be made. Petroleum products, Fertilizers, pesticides, pharmaceuticals, and so much more. Life would be very different without all those.
The Claisen adapter is a good tip. Putting the heating mantle and boiling flask on top of a lab jack or similar is also good. This keeps you from needing to figure out how to get the heating mantle out from under it when stuff's popping off.
Thats true, I always forget about lab jacks. Very useful, too bad they are so expensive. lol
i like the korn in the intro
You could also make levoglucosenone this way, using H2SO4 as the catalyst.
cool video, shouldn't the title be Organic chemistry: Converting corn cobs to furfural
3:35 This is why low-cut filters are a thing.
I don't think that would fix the problem you are taking about.
@@WheelerScientific Certainly not the best way, but expedient and somewhat effective. Table bumps are rather jarring when heard over headphones.
Isn't furfural decently toxic?
I'm guessing you work in a research lab, and that's how you have access to NMR and GC-MS?
Yes. lol
Converting corn to cancer. Nice. 👍
I think you should maybe Google what sweet bread is. You'll see that the description of what you're smelling is very confusing.
Sweet Bread and Sweetbread are two different things.
Is it pronounced more like "fear for all" or "fur for all"
Unless you are a furryphobic, then same thing..
Fur fur Al. Exactly how it’s spelled. Suffix is pronounced Al like in the name Albert. It denotes that’s there’s an aldehyde group.
The suffix -Ol (pronounced: “all”) denotes an alcohol group
