EC number: 293-262-2 | CAS number: 91053-00-8 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 95°C to 120°C (203°F to 248°F).
