Amfani
Ana amfani da shi azaman kayan da aka yi amfani da su wajen samar da robar roba, resin roba, zare na roba, plasticizer, fenti na latex, da sauransu. Butadiene shine babban kayan da aka yi amfani da su wajen samar da robar roba (robar styrene-butadiene, robar cis-polybutadiene, robar nitrile-butadiene, robar chloroprene). Tare da haɓaka robobi na styrene, ta hanyar haɗa styrene da butadiene, ana samar da resins daban-daban tare da aikace-aikace masu yawa (kamar resin ABS, resin SBS, resin BS, resin MBS), wanda ke sa butadiene a hankali ya mamaye matsayi mai mahimmanci a cikin samar da resin. Bugu da ƙari, ana amfani da butadiene wajen samar da ethylidene norbornene (monomer na uku na robar ethylene-propylene), 1,4-butanediol (roba na injiniya), adiponitrile (monomer na nailan 66), sulfolane, anthraquinone, tetrahydrofuran, da sauransu. Saboda haka, shi ma muhimmin kayan sinadarai ne na asali. Butadiene kuma yana da amfani da yawa wajen samar da sinadarai masu kyau. Sinadaran da aka samar ta amfani da butadiene a matsayin kayan masarufi galibi sun haɗa da waɗannan fannoni: (1) Yana yin aikin Diels-Alder tare da mahaɗan dieneophile marasa electron don samar da anthraquinone, kuma abubuwan da ya samo asali sune mahimman abubuwan da ke haifar da rini, magungunan kashe ƙwayoyin cuta, da magungunan kashe ƙwari. (2) Yana yin aiki tare da maleic anhydride (wanda aka taƙaita a matsayin maleic anhydride) sannan ya taru don samar da tetrahydrophthalic anhydride, wanda za'a iya amfani da shi azaman maganin warkarwa da kuma plasticizer don resin polyester da resin epoxy. Lokacin da tetrahydrophthalic anhydride ya ƙara oxidize ta nitric acid, ana iya samun butane tetracarboxylic acid, wanda shine kayan aiki na asali don ƙera fenti mai narkewar ruwa. Hakazalika, lokacin da aka yi hydrogenated tetrahydrophthalic anhydride don samun hexahydrophthalic anhydride, ana iya amfani da shi azaman maganin warkarwa don resin epoxy. (3) Yana yin aiki da sulfur dioxide don samar da sulfolene, sannan a tsara shi zuwa ruwan da aka yi amfani da shi wajen samar da sinadarin hydrogen a gaban wani sinadarin nickel mai ƙashi don samar da sulfolane, wanda shine sinadarin da ake amfani da shi wajen cire iskar carbon dioxide. Ana iya amfani da cakuda sulfolane da diisopropanolamine don cire iskar carbon dioxide. (4) Haɗakar telomerization ta layi na butadiene yana da amfani sosai a masana'antu. Bayan dimerization ta layi, ana samun olefin madaidaiciya mai sarka takwas na carbon, kuma bayan aldehydation da hydrogenation, ana samun nonanol, wanda ke da amfani mai mahimmanci wajen haɗa ƙamshi na roba, surfactants, da ƙarin mai. Ta amfani da hadadden cobalt a matsayin mai kara kuzari, dimer, trimer, da tetramer duk kayan masarufi ne don haɗa manyan alcohols da musks na macrocyclic. Yana narkewa a cikin alcohols da ethers, kuma ana iya narkar da shi a cikin acetone, benzene, dichloroethane, amyl acetate, furfural, da maganin cuprammonium acetate. Ba ya narkewa a cikin ruwa.
