> By the way oxalic acid fumes as soon as it touches a surface it becomes
particles due to surface temperature below the required sublimation
temp.
From what I observe, at normal ambient temperatures, the recrystallization
is well underway within inches of the nozzle, as evidenced from the stream
going from transparent to white. When I direct the vapor into an
uninflated mylar balloon, no inflation takes place, indicating that all the
OA vapor condenses immediately long before it hits an actual surface. I
only observe inflation of the balloon once the temperature of the OA
vaporizer exceeds 190C, thus causing the OA to degrade to CO2 and water
(the formic acid produced degrades immediately).
