| Applications | |
| Used as a co-monomer for the production of high density (HDPE) and linear low density (LLDPE) polyethylene products and for the manufacture of polybutylene. Butene serves also as a feedstock for the production of 1,2 butylene oxide, methylethylketone (MEK), maleic anhydride and n-butyl derivatives. | |
