CAUTION
Do not produce anhydrous perchloric acid, either from its salts or from aqueous
solutions, e.g. by heating with high boiling acids or dehydrating agents such as
sulfuric acid or phosphorous pentoxide. In addition to spontaneous explosion, the
anhydrous acid explodes instantaneously on contact with oxidizable organic
materials.
CAUTION
Limit the use or storage of perchloric acid to quantities less than 500 g per fume hood.
