Dear Colleagues,
Recently I encountered an explosion and would like to get some possible
reasoning from you. I would greatly appreciate it if anyone of you who
have experienced the similar kind of incidence could help me solve the
problem.
I tried to reduce the nitro group of  Nitro-Dimethoxybenzaldehyde by
using iron powder in NH4Cl solution and the substrate was dissolved in
MeOH. After that the filtrate( which contained the reduced product)was
kept in the vacuum desicator to evaporate off the MeOH by applying
reduced pressure through water suction( it was left overnight).
Unfortunately, the vacuum desicator exploded (a very forceful one!)
after abt 12 hrs of suction.Till now, I'm still trying to figure out the
various posible reasons that could have caused the explosion, but in
vain.
I would greatly appreciate it if anyone of you could (especially,those
of you who experienced it before)offer me some possible reasons.
Thanks in advance,
Barnabas
