Table 1 Common chemicals that form explosive levels of peroxides and their storage limits
|Form potentially explosive peroxides without concentration (a). Dispose or test 3 months after opening.
||Form potentially explosive peroxides on concentration (b). Dispose or test 12 months after opening.
||Autopolymerize as a result of peroxide accumulation. Dispose or test inhibited materials after 12 months.
|Butadiene (c)||Acetal||Acrylic acid|
|Divinyl acetylene||Benzyl alcohol
|Ethylene glycol dimethyl ether
|Methyl isobutyl ketone
|2-propanol (isoproranol, "IPA")
|Other secondary alcohols
(a) Store under nitrogen, if practical.
(b) WARNING! May become unstable if concentrated intentionally or accidentally by user.
(c) When stored as an inhibited liquid monomer.
(d) When stored as a liquid monomer.
(e) When stored as a gas.
