Peracetic Acid - Questions regarding Explosivity

iodide - 16-6-2005 at 05:44

Peracetic Acid seems to be a useful means of oxidizing in several reactions I've run across (and especially in the two step-conversion of isosafrole to Methylenedioxyphenyl-2-propanone (MDP2P). Different concentrations are used, however.

While I recognize that organic peroxides are unstable, and would never ever play with >50% Peracetic Acid, realistically, what is the explosive potential of 15% peracetic acid, a relatively dilute level?

Will a low reflux (as called for in the isosafrole conversion) risk explosion or is this dilution sufficiently hydrated that explosion fears are unfounded?

Take a look at this book:

Bretherick's handbook of industrial chemical hazards vol 1 and 2:

Thanks so much for the Resouce - BUT

..the Handbook does not refer to more dilute concentrations. 15% Peracetic Acid is significantly more dilute than the 40% they refer to.

Perhaps I'm mistaken but doesn't the increased presence of water mitigate the instability of the acid - at least with respect to explosivity?
