Ingcaciso yeMveliso
Kodwa-2-ene i-alkene ye-acyclic ene-athomu ezine zekhabhoni. Yeyona alkene elula ebonisa i-cis/i-trans-isomerism (eyaziwa ngokuba yi-(E/Z)-isomerism); oko kukuthi, ikhona njenge-isomers ezimbini zejometri cis-kodwa-2-ene ((Z)-kodwa-2-ene) kunye ne-trans-kodwa-2-ene ((E)-kodwa-2-ene).
I-isomer ezimbini kunzima kakhulu ukuzohlula ngokuxutywa kwe-distillation ngenxa yokuba kufutshane kwamanqaku azo abilayo (~4 °C kwi-cis kunye ne-1 °C ye-trans[5]). Nangona kunjalo, ukwahlukana akuyomfuneko kuninzi lwezicwangciso zemizi-mveliso, njengoko zombini i-isomers ziziphatha ngendlela efanayo kuninzi lweempendulo ezifunwayo. Umxube oqhelekileyo wezoshishino kodwa-2-ene yi-70% (Z)-kodwa-2-ene (cis-isomer) kunye ne-30% (E)-kodwa-2-ene (i-trans-isomer). I-Butane kunye ne-but-1-ene zizinto ezingcolileyo eziqhelekileyo, ezikhoyo kwi-1% okanye ngaphezulu kwimixube ye-industrial, equlethe ixabiso elincinci le-isobutene, i-butadiene kunye ne-butyne.
