hydrazine safety
« on: September 30, 2008, 10:50:33 PM »
I am goint to disolve copper or selenium in hydrazine (1M solution of THF or hydrazine hydrate).
However, I wonder if it is not explosive in air.  Safety guide shows that Contact with many materials may cause fire or explosive decomposition. May react explosively with a variety of materials,  

Please let me know how I can handle it.

Hi there

in many cases hydrazines are combustible/explosive when dry and exposed to air.

hydrazine vapor in air is flammable at 4.7 to 100% hydrazine by volume - handle under nitrogen!
Some metals and alloys including monel, bronze, brass, cadmium, gold,
molybdenum, and stainless steel with more than 0.5% molybdenum
or rust cause decomposition of hydrazine

so keep it 'wet' and under nitrogen

hope this helps
