| Hazard Information | Back Directory | [General Description]
tert-Butyl peroxyisobutyrate is particularly sensitive to temperature rises. Above a given "Control Temperature" they decompose violently. tert-Butyl peroxyisobutyrate is generally stored or transported in a solvent slurry. Solvent is usually benzene. Responders must regard hazards of the peroxide as well as the benzene solvent. | [Reactivity Profile]
TERT-BUTYL PEROXYISOBUTYRATE explodes with great violence when rapidly heated to a critical temperature; pure form is shock sensitive and detonable [Bretherick 1979 p. 602]. | [Hazard]
Flammable, dangerous fire risk. Oxidizing
agent.

Notclassified | [Purification Methods]
After diluting 90mL of the material with 120mL of pet ether, the mixture is cooled to 5o and shaken twice with 90mL portions of 5% NaOH solution (also at 5o). The non-aqueous layer, after washing once with cold water, is dried at 0o with a mixture of anhydrous MgSO4 and MgCO3 containing ca 40% MgO. After filtering, this material is passed, twice, through a column of silica gel at 0o (to remove tert-butyl hydroperoxide). The solution is then evaporated at 0o/0.5-1mm to remove the solvent, and the residue is recrystallised several times from pet ether at -60o, then subjected to high vacuum to remove traces of solvent [Milos & Golubovic J Am Chem Soc 80 5994 1958]. Handle with adequate protection due to possible EXPLOSIVE nature. |
