A complex combination of hydrocarbons obtained from distillation of the butadiene-free C4 fraction of a naphtha steam-cracking process. It consists predominantly of olefinic hydrocarbons having carbon numbers of C8, C12, C16 and C20 and boiling in the range of approximately 170°C to 185°C (338°F to 365°F).
The acute inhalation toxicity of
diisobutylene was evaluated in a 4-hour, single exposure study in male
and female albino rats. There were no mortalities and no overt signs of
toxicity. The acute LC50 of diisobutylene was greater than
4185 ppm, equivalent to 19171 mg/m3 air.
