What is this?
I attempted to make hydrazine using glycerol instead of gelatin.
When I boiled it to 1/3 the original and the solution turned dark red. What is this red stuff? It smells kind of like nuts.

I assume you were doing the hypochlorite method. Consider that the haloform reaction can be run on ethanol because hypochlorite will oxidise the
alcohol to aldehyde, which then udergoes the haloform reaction proper. Then reflect on the fact that glycerol contains three H-C-O-H fragments, which
can similarly be oxidised.
Not knowing the relative proportions of reactants, I'd have to guess "a mess". You can get hydroxy- aldehydes and ketones from the glycerol, which
might react with the ammonia. Under some oxidising conditions diols can fragement, glycerol gives formic acid and formaldehyde, if that did occur the
H2CO would likely condense with the other carbonyls giving a range of products.
While gylcerol will complex with metal ions, it doesn't really work very well as a chelating agent, in some cases the glycerol complex can be used at
a catalyst, exactly the opposite of what you want.

Man, then why did the procedure say it could be used?

I tried glycerol and NaOH and glycerol with NaOCl. Both were boiled for about 10minutes. Only NaOCl solution turned red and started precipitating
NaCl.
Reactions with acid and base:
The main solution was poured into 3 beakers and diluted with: water, NaOH solution, and vinegar.
The water-diluted one looked like a light peach-brown color.
The other one reacted with NaOH to make a yello solution.
The other one reacted with acetic acid to turn to a very pale lime color (almost colorless).
What structural properties can be determined from this?

Red solution reacts with copper sulfate and NaOH to form a yellow-orange precipitate presumably Cu2O.

Which procedure? From here so you can point to it?
The copper test sure sounds like aldehyde.

Megalomania's procedure.
"It is possible to use starch, glue, or glycerol instead of gelatin, but they are inferior."

Does anyone know any information about the compound 2-oxopropane-1,3-dial?
CHO--C(O)--CHO
Some synonyms are:
Oxopropanedial
Oxomalonaldehyde
Mesoxaldialdehyde
MESOXALALDEHYDE
This compound seems to have the ability to display resonance when in basic solution therefore color?
