1-Butene Use and Manufacturing

Methods of Manufacturing

In the cracking of petroleum fraction naphtha, the content of 1-butene in the C4 component obtained by the tube furnace cracking method and the steam cracking method reaches about 35%, and 1-butene can be obtained by separating the C4 fraction.

Uses

One of the important basic chemical raw materials. Hydration of butene to sec-butanol can further produce methyl ethyl ketone, oxidative dehydrogenation to butadiene, catalytic oxidation to maleic anhydride and acetic acid, 1-butene self-polymerization can produce poly 1-butene, linear low density copolymerization with ethylene Polyethylene.
