Hexamine synthesis in aluminium vessels
Hello everybody . I am synthesizing hexamine .i have proper glass equipment and i make it easily in them . Yesterday my friend asked me is it safe to
make it in aluminium vessel . I am not sure about this so i am asking you is it safe to make hexamine using formaline and ammonium hydroxide in
aluminium vessel . If i boil ammonium hydroxide and formaline in aluminium vessel will they react with aluminium or hexamine will be formed

Ammonium hydroxide/hexamine does not corrode aluminum. Source: http://www.usmotors.com/TechDocs/ProFacts/Corrosive-Chemical...

I wouldn't use ammonia solution in aluminum. I've seen it attack aluminum pans. Maybe with the right choice of alloy this problem can be avoided or
minimized but I think it's easier to just use something else.
The less you bet, the more you lose when you win.

aluminium reacts strongly with strong bases, my problem is that bioling the weak base will dissociate more OH- ions and at a certain temperature it
will react with aluminium so...
teflon is widely used in non stick pans, just buy a teflon pan and use that, if you look after your pan it will see you alot of use as the teflon is
impervious to all but a select few nasty chemicals
http://en.wikipedia.org/wiki/Polytetrafluoroethylene
"High corrosion resistance favors the use of PTFE in laboratory environments as containers, as magnetic stirrer coatings, and as tubing for highly
corrosive chemicals such as hydrofluoric acid, which will dissolve glass containers."
also be carefull, Hexamethylene triperoxide diamine is a hell of an explosive, safety first, make sure you only prepare small quantities at a time and
use a blast shield, and when detonating use an electronic fuse

Copper free aluminium alloys are often used to store bulk concentrated ammonium/water solutions.
Any copper containing Al alloys can be pitted/corroded, the higher the level of Cu the faster the damage.
