Asi-2-ene is an acyclic alkene ine maatomu mana ecarbon. Ndiyo alkene yakapfava inoratidza cis/trans-isomerism (inozivikanwawo se (E/Z) -isomerism); ndiko kuti, iripo semaisomeri maviri ejometri cis-asi-2-ene ((Z)-asi-2-ene) uye trans-asi-2-ene ((E)-asi-2-ene).
Iwo maisomer maviri akaoma zvikuru kupatsanurwa ne distillation nekuda kwekuswedera kwemapoinzi awo ekuvira (~4 °C ye cis uye ~ 1 °C ye trans[5]). Nekudaro, kupatsanurana hakufanirwe mune akawanda maindasitiri marongero, sezvo ese ari maviri isomers anoita zvakafanana mune mazhinji ezvinoda kuita. Musanganiswa wemaindasitiri asi-2-ene musanganiswa 70% (Z)-asi-2-ene (cis-isomer) uye 30% (E)-asi-2-ene (trans-isomer). Butane uye but-1-ene tsvina yakajairika, iripo pa1% kana kupfuura mumisanganiswa yeindasitiri, inewo mashoma eisobutene, butadiene uye butyne.
