Gasi wopanda mtundu wokhala ndi fungo lonunkhira bwino, losavuta kusungunuka. Kusungunuka mu mowa ndi ether, komanso kusungunuka mu acetone, benzene, dichloroethane, amyl acetate, furfural, ndi copper ammonia acetate solution. Zosasungunuka m'madzi.

1) Diels-Alder reaction imapezeka ndi ma elekitironi-deficient dienophilic compounds kuti apange anthraquinone, zomwe zotumphukira zake ndizofunika pakati pa utoto, fungicides ndi mankhwala ophera tizilombo. (2) Kuchita ndi maleic anhydride (wotchedwa maleic anhydride) ndiyeno condense kupanga tetrahydrophthalic anhydride, amene angagwiritsidwe ntchito ngati wochiritsira ndi plasticizer kwa poliyesitala utomoni ndi epoxy utomoni. Tetrahydrophthalic anhydride ndiye amathiridwa ndi nitric acid kuti apeze butane tetracarboxylic acid, yomwe ndi zinthu zopangira utoto wosungunuka m'madzi. Mofananamo, tetrahydrophthalic anhydride ndi hydrogenated kuti apange hexahydrophthalic anhydride, yomwe ingagwiritsidwe ntchito ngati mankhwala ochizira epoxy resin. (3) Amachitira ndi sulfure woipa kuti apange cyclobutene Chemicalbook sulfone, amene kenako anakonza mu njira amadzimadzi ndi hydrogenated pamaso pa mafupa faifi tambala chothandizira kubala cyclobutene sulfonane, amene ndi kusankha zosungunulira kwa onunkhira hydrocarbon m'zigawo. Kusakaniza kwa sulfonane ndi diisopropanolamine kungagwiritsidwe ntchito ngati mpweya wa decarbonation. (4) Liniya ya telomerization reaction ya butadiene ndiyothandiza kwambiri m'makampani. Pambuyo pa mzere wa dimerization, olefin wamtundu wa 8-carbon straight-chain olefin amapezedwa, omwe kenako amakhala hydroformylated ndi hydrogenated kuti apeze nonanol, yomwe imakhala ndi ntchito zofunika pakuphatikiza mafuta onunkhira, zopangira mafuta, ndi zowonjezera mafuta. Pogwiritsa ntchito cobalt complex monga chothandizira, dimerization yake, trimerization ndi tetramerization zonse ndi zipangizo zopangira mowa wambiri ndi macrocyclic musk.
