An olefinic hydrocarbon recovered from refinery or petrochemical processes, which is gaseous at standard temperature and pressure. Butylene is used in the production of gasoline and various petroche [..]

(n) any of three isomeric hydrocarbons C4H8; all used in making synthetic rubbers

A hydrocarbon substance consisting of molecules composed of four atoms of carbon and eight atoms of hydrogen, used primarily for blending in high-octane gasoline, for residential and commercial heating and in manufacture of chemicals and synthetic rubber.

Also called butene, any of four isomeric compounds belonging to the series of olefinic hydrocarbons. They are formed during the cracking of petroleum to produce gasoline; they can also be prepared commercially by the catalytic dehydrogenation of butanes. The major part of the butenes is utilised for the production of octanes, which are important co [..]
