EC number: 293-263-8 | CAS number: 91053-01-9 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).
