Photolytic. At 25 °C, a rate constant of 4.58 x 10-12 cm3/molecule?sec was reported for the gasphase
reaction of tert-butylbenzene with OH radicals (Ohta and Ohyama, 1985).
Chemical/Physical. tert-Butylbenzene will not hydrolyze because it has no hydrolyzable
functional group (Kollig, 1995). | [Purification Methods]
Wash it with cold conc H2SO4 until a fresh portion of acid is no longer coloured, then with 10% aqueous NaOH (care-effervescence), followed by distilled water until neutral. Dry it (CaSO4), and distil it in a glass helices-packed column, taking the middle fraction. [Beilstein 5 IV 1045.] | [Toxics Screening Level]
The initial threshold screening level (ITSL) for t-Butyl benzene is 10 μg/m3 based on an annual averaging time. |
