Методы очистки
Crystallise it twice from EtOH, then repeatedly melted and frozen at 30mm pressure. [Williams & Smyth J Am Chem Soc 84 1808 1962.] Alternatively it is dissolved in Et2O, dried over CaCl2 and Na, filtered, evaporated and the residue is sublimed in a vacuum [NMR: Hana & Koch Chem Ber 111 2527 1978].
Несовместимости
Forms explosive mixture with air.
Emulsions in xylene may violently decompose on contact
with iron or aluminum above 70C. Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may
cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides. Contact
with reducing agents may cause exothermic reaction,
releasing flammable hydrogen gas
Утилизация отходов
Dissolve or mix the material
with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal,
state, and local environmental regulations must be
observed.
