To report what has been happening in my quest to get some NHN... turns out the reason why I failed is because both my first and second hydrazine
sulfate synthesis were duds. I am not sure where the process failed. But it turned out I didn't get any hydrazine sulfate at all.
That being said. Tonight i decided to make some hydrazine sulfate and I made a full batch. When I added the sulfuric acid, even though it was already
at a 27 or so C, the hydrazine sulfate precipitate immediately began to form. I only let it cool to 18C before beginning filteration. I haven't
weighed my yield yet, but I hope I have enough for a good synthesis or two.
That being said, I need to ask this one question... because to me making hydrazine sulfate has not proven to be dangerous... neutralizing the
byproducts IS. The first time I did it I poured in a calcium hypochlorite solution into the leftover hydrazine in my bathroom and the fumes were
unbearable. It took a long time to clean everything up.
My second time was better, but I wasn't sure if I needed to give it time to fully neutralize, but I did use a lot of bleach mixed with calcium
hypochlorite.
The third time... maybe it was because I was using a full batch... my god I think I nearly died! What happened is that I initially poured water, the
hydrazine leftovers, and bleach into my glass baking pan that I only use for chemistry now... and then I added a bit more bleach and the solution
fizzed. Then I added a good amount of calcium hypochlorite to the thing and mixed it, letting it fizz and fizz and so on.
My pan was too full to add anything else. I figured I would do what I did previously and put it in my bathtub and pour water over it until everything
went down the drain... but instead I went to my kitchen sink.
While carrying the thing I didn't smell anything, but the moment I got to my kitchen sink it's almost like being in a gas attack! My eyes teared up
and I coughed violently. I turned on the faucet and ran away. I let the thing run for a while before returning and the gasses were still there. Just
very isolated. I held my breath before approaching again and made sure the water was pouring away the undissolved calcium hypochlorite. After
everything seemed to wash away I was in a bit of a tizz over the whole thing.
I wasn't short of breath or had any of those symptoms. I decided to leave my kitchen sink on and leave my apartment for a long walk. I had no problem
breathing, albeit I was worried I was feeling some minor sensation when I took a full breath. I started to salivate a little after around 45 minutes
but that stopped after around 20 minutes.
That was one hell of an experience that I hope to never repeat. Someone just told me that the hydrazine byproducts can be flushed down the toilet or
drain and the bacteria in the sewer system will take care of it. Is this true? Because disposing of that stuff is the only thing I ever worry about.
