Source

Almost all commercially produced butenes are obtained as by-products

  • catalytic or thermal cracking, refinery processes which upgrade high fractions to gasoline, and
  • steam cracking, which produces light olefins for chemical feedstocks hydrocarbons derived from natural gas or crude oil.
The butenes obtained are withdrawn as a mixture from the C4-fraction. From this mixture butadiene and butanes are separated by extractive distillation. The remaining butenes cannot be separated by mere distillation because their boiling points are too close together.
In a first step iso-butene is isolated either by etherification with methanol to form methyl tert-butylether (MTB), or by hydrating iso-butene to tert-butanol (TBA). In this step all other C, components in the mixture remain unchanged. MTB and TEA can then be split by reversing synthesis to produce high purity iso-butene.

Once the iso-butene content has been reduced, recovery of high purity 1-butene is possible by fractionation. The remaining 2-butenes can be separated by molecular sieve absorption methods.
Other commercial processes that are sometimes used to produce specific isomers or mixtures of butenes or both, either directly or as by-products, include:
  • the oxirane process for making propylene oxide (-> iso-butene)
  • the dehydrogenation of butane and iso-butane (-> 1-butene, cis-2-butene, trans-2- butene)
  • the disproportionation of olefins (-> cis-2-butene, trans-2-butene)
  • the oligomerization of ethylene (-> 1-butene).

AU or any of them may become useful feedstock sources should the need arise.

Applications
iso-Butene is mainly used as a chemical intermediate
iso-Butene is also used in the production of acid and alkaline resistant rubber.
