what is the best way of releasing formaldehyde gas? - (Nov/13/2008 )
Hello,
I wasn't entirely sure which subject to place this in, so I apologise if some people think it is in the wrong one...
basically, I would like to be able to release formaldehyde in the gaseous state. What is the best way to do this? do i need to heat paraformaldehyde (a bit dangerous), or a concentrated formalin solution...? I really seem to find conflicting reports all over the place about formaldehyde/paraformaldehyde etc...
So if anyone can clear this up, it wpuld be very much appreciated.
Thank you!

Heating is not dangerous at least at 65'C. It may be dangerous to health (respiratory irritation, headache are the most obvious) if you don't have a way to contain the gas, but it is not going to explode for sure at 65'C.

Thanks very much for this information - do you have any more knowledge of it? For example, concentrations I would need to use to heat to release the gas?
Sorry, I've just of something else. Will it release the gas if it is in the aqueous soultion of say formalin? (40% i think it comes, which i think is saturation?) Or would it be best to dissolve paraformaldehyde in a different solvent?
Thanks again for any help...
