1-butene is   mainly derived from the ethylene plant and the by-product C4 fraction of the   catalytic cracking unit of the refinery and ethylene dimerization in China.   The boiling point of 1-butene and isobutylene is very close, only 0.6 °C, the   relative volatility is only 0.005.

APPLICATION   SCOPE

1-butene is a raw material for the synthesis of sec-butanol and   dehydrogenation to butadiene; for the production of butadiene, isoprene,   synthetic rubber, etc.
