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.
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.
