When I freebase my hydrazine sulfate with sodium hydroxide and ethanol, I also need to filter out whatever solids that are left behind (my process for
hydrazsulfate always has a little sodium sulfate in it). One thing that he is doing that I must do next is add nickel nitrate until I get that excess
added and used up all my hydrazine freebase. since I didn't know you could do that (and easily get rid of the surplus, since NHN is water insoluble).

Where did they say they used isopropyl alcohol to liberate hydrazine? My understanding was they dissolved hydrazine sulfate in water then added sodium
hydroxide to pH 8, heated the solution, then added the nickel nitrate solution. The isopropyl alcohol was used to wash the product.

I need to make more NHN soon, since I am running out. The last time I made it, one of the batches I made seemed sub par. I wonder how well it would
work as a cap on its own. I need to test them. |

I stand corrected. I was confusing videos in my mind with one where Chemplayer freebases hydrazine with IPA and Ethanol in two separate attempts.
I did remember that Raid said he did liberate it with just water. I might do that next time if it is easier. Just keeping in mind that the pH needs to
be 8 or thereabouts. I'm probably going to continue to use the old ethanol method since it worked for me quite a few times.

I always lit my NHN from the top and not the bottom, but that is some slow burning stuff. I think there is something wrong with it, but sadly I cannot
tell what... :\
