making calcium cyanamide using a well established procedure in which urea is first melted with calcium oxide to form an intermediate product- calcium cyanate. this is then further heated to around 800C for about an hour which yields the final product- calcium cyanamide. in all honesty i found this method superior over the wet chemical method i used in another video despite all the ammonia evolved. there was less steps and in a couple of hours you could have a batch of cyanamide ready to go. it also helped greatly that i had excellent temperature control with a furnace i had recently constructed. in the end the product identity was confirmed using the known method involving ammoniacal silver nitrate which gives us bright yellow silver cyanamide.

is calcium oxide necessary or can ca(oh2) be used?
Calcium oxide is required. You can just drive off water from the hydroxide
@AllChemystery could you not potentially use CaCO3 with urea and decompose it to CaO in situ at the high tempertures needed to converted the cyanate to cyanamide? or would this destroy the urea?
Oh man I too like mixing chemicals in those ziplock bags!! I thought I was the only weirdo does that.
Aussie Chemist makes things easier!
What is the purity, the percentage ??
Are you from Germany
... Thiourea?
JamesG chemplayer just made a video on it
Yes, I knew that. His video makes thiourea dioxide from thiourea and peroxide. Your calcium cyanamide is a precursor to thiourea -- which he does not show how to make.
According to Wikipedia you need to react it with H2S in the presence of CO2, does not sound very easy or very pleasant.
I did your synthesis of picric acid exactly and for some strange reason I only got Dinitrophenol and not trinitrophenol. Is there anyway you think I can improve it or maybe make the dinitro trinitro
science_and_anonymous here are the exact synthesis instructions: https://www.sciencemadness.org/whisper/files.php?pid=311232&aid=28045. If you followed this precisely then you really should have picric acid. I’m not sure what went wrong.
AllChemystery yeah maybe I didn't get it hot enough on the last lap of the di to tri. Anyway, can't wait to see those tetrazoles with this stuff ;)

What was the temp controller for your furnace called again PPD or SSR?
