General description
2-Methyl-2-butene (β-Isoamylene, Amylene) is a trisubstituted olefin. It acts as guest and forms stable solid host-guest complexes with self-assembled benzophenone bis-urea macrocycles. The effect of active chlorine formulations on photodecomposition of 2-methyl-2-butene has been studied. Its reaction with ozone in gas-phase has been reported to afford carbonym derivatives.
Application
2-Methyl-2-butene may be employed as precursor for peroxyacetyl nitrate for the calibration purposes.
Recommended products
Brass hose adapter Z146811 or brass body mini gas regulator Z513539 is recommended.
