If i was to boil piss until all the water evaporates, and then i boiled the sludge on the bottom, would it create phosphorus?
I believe you can get phosphorus from piss yes but I'm not sure how exactly you'd go about isolating it, and you'r not "creating" it anon its already in there your just separating it out.
Also >>7585565 it may be a very small amount at then end, you might need allot of piss to get any meaningful amount.
If you were to eat a gram of unsubstituted phenethylamine every hour, collect and concentrate your piss and then extract with a suitable solvent, you'd have quite a lot of phenylacetic acid.
OP here, me and my friend pissed into a thing and let it boil on the stove, however it smelled terrible and i was scared of it smelling for the rest of the week so i stopped.
It boiled and i'll try again another day
