olefine和alkene有区别吗? from wiki. in organic chemistry , an alkene , olefin , or olefine is an unsaturated chemical compound containing at least one carbon -to- carbon double bond . the simplest acyclic alkenes, with only one double bond and no other functional groups , form a homologous series of hydrocarbons with the general formula cnh2n . the simplest alkene is ethylene (c2h4), which has the international union of pure and applied chemistry (iupac) name ethene . alkenes are also called olefins (an archaic synonym, widely used in the petrochemical industry ). aromatic compounds are often drawn as cyclic alkenes, but their structure and properties are different and they are not considered to be alkenes. 两者都 是“烯烃”，含有至少一个c=c双键的不饱和烃，它们是同义词。 olefin 是古体用法，多用于石油化工领域，因此这个我比较常见。 查看更多
