Urgent need to verify: Has anyone heard of a situation where a given chemical
can shift its falshpoint over time? The chemical I am specifically concerned
with is Diacetone alcohol (DAA), which is said to have an as manufactured
flashpoint of 146 degrees F. Can anyone confirm that this chemical will shift
to a lower flashpoint after manufacture when in storage? Why would this occur?
