Moderate fire risk. Toxic in high concentration, a skin and eye irritant. | [Chemical Properties]
CLEAR COLOURLESS LIQUID | [Physical properties]
Clear, colorless, liquid with an odor resembling butylbenzene, tert-butylbenzene, ethylbenzene, or
toluene. An odor threshold concentration of 80 μg/kg was reported (quoted, Verschueren, 1983) | [Uses]
Intermediate for perfumery and analgesic anti-inflammatory (Ibuprofen). | [Definition]
ChEBI: Isobutylbenzene is an alkylbenzene that is benzene carrying an isobutyl substituent. | [Preparation]
Isobutylbenzene synthesis: Isobutyrophenone, underwent a Wolff–Kishner reduction using hydrazine hydrate and strong base conditions to synthesize isobutyl benzene. The solvent for this reaction was replaced with the more sustainable solvent glycerol. The glycerol for this reaction was obtained from the synthesis of biodiesel. The reaction was allowed to heat at reflux (149–155 °C) for a period of three hours. An average 51 % yield of isobutyl benzene was obtained from the solar synthesis, compared to a 55 % yield from an in-lab, electrical heating analysis.

Isobutylbenzene is synthesized by the isopropylation at the side chain over Na, K and Cs exchanged zeolites. | [Environmental Fate]
Biological. Oxidation of isobutylbenzene by Pseudomonas desmolytica S44B1 and
Pseudomonas convexa S107B1 yielded 3-isobutylcatechol and (+)-2-hydroxy-8-methyl-6-oxononanoic
acid (Jigami et al., 1975).
Chemical/Physical. Complete combustion in air yields carbon dioxide and water vapor.
Isobutylbenzene will not hydrolyze because it has no hydrolyzable functional group. |
