1-BUTENE synthesis

13synthesis methods
Most butenes are produced in the cracking process in refineries along with other C-4 fractions such as the butanes. Butenes are separated from other compounds and each other by several methods. Isobutene is separated from normal butanes by absorption in a sulfuric acid solution. Normal butenes can be separated from butanes by fractionation. The close boiling points of butanes and butenes make straight fractional distillation an inadequate separation method, but extractive distillation can be used. Butenes can also be prepared from the dehydrogenation (elimination of hydrogen) of butane.
