maybe a hydro carbon
« on: January 31, 2007, 02:26:05 PM »
hi guys ;D
I'm looking for a molecule that includes carbon in its structure, with a reaction with some other chemical by any means eg heat . it leaves its carbon behind and the carbon does not combine with any other molecule instead itself. maybe this can be achieved in a vacuum

IIRC if you react a sugar (e.g. sucrose, table sugar) with sulfuric acid, you get carbon residue.

won't you get carbon residue by heating it to decomposition as well?

how about Polymer-Sugar any way to get rid of oxigen and hydrogen with keeping the carbon structure?

Glucose, I think.

Yeah, it's the beta anomer of d-glucose (specifically beta-d-glucopyranose, you've got to love carbohydrate nomenclature).
My research: Google Scholar and Researchgate

Ugh, I hate sugars.  I think glucose is the only one I remember because everything is equatorial (at least in the beta-anomer).
