1-butene(1-C4H8),the smallest unsaturated hydrocarbon with a secondary allylic carbon group,has been investigated intensively recently either in combustion experiments or in theoretical calculations[1].The related chemical kinetic mechanism is quite significant to the development of real fuels since 1-butene is considered as one of the most important intermediates in the combustion of large hydrocarbons and oxygenated fuels[2].
