Ukusetyenziswa
Isetyenziswa njengezinto zokwenza irabha yokwenziwa, i-resin yokwenziwa, ifayibha yokwenziwa, i-plasticizer, ipeyinti ye-latex, njl. I-Butadiene yeyona nto iphambili yokwenza irabha yokwenziwa (irabha ye-styrene-butadiene, irabha ye-cis-polybutadiene, irabha ye-nitrile-butadiene, irabha ye-chloroprene). Ngophuhliso lweplastiki ye-styrene, ngokudibanisa i-styrene kunye ne-butadiene, kuveliswa ii-resins ezahlukeneyo ezinezicelo ezininzi (ezifana ne-ABS resin, i-SBS resin, i-BS resin, i-MBS resin), nto leyo eyenza i-butadiene ithathe indawo ebalulekileyo kwimveliso ye-resin. Ukongeza, i-butadiene ikwasetyenziswa kwimveliso ye-ethylidene norbornene (i-monomer yesithathu yerabha ye-ethylene-propylene), i-1,4-butanediol (iplastiki yobunjineli), i-adiponitrile (i-monomer ye-nylon 66), i-sulfolane, i-anthraquinone, i-tetrahydrofuran, njalo njalo. Ke ngoko, ikwayinto ebalulekileyo ebalulekileyo yekhemikhali. I-Butadiene ikwasetyenziswa kakhulu ekuveliseni iikhemikhali ezintle. Iikhemikhali ezintle ezilungiselelwe kusetyenziswa i-butadiene njengezinto eziluhlaza ziquka ezi zinto zilandelayo: (1) Idlula kwi-Diels-Alder reaction kunye neekhompawundi ze-dieneophile ezingenayo i-electron ukuvelisa i-anthraquinone, kwaye izinto eziphuma kuyo zizinto ezibalulekileyo zedayi, iifungicides, kunye nee-insecticide. (2) Isabela kwi-anhydride ye-maleic (efinyeziweyo njenge-anhydride ye-maleic) ize emva koko ijiye ivelise i-anhydride ye-tetrahydrophthalic, enokusetyenziswa njenge-agent yokunyanga kunye ne-plasticizer yee-resin ze-polyester kunye nee-resin ze-epoxy. Xa i-anhydride ye-tetrahydrophthalic i-oxidized ngakumbi yi-nitric acid, i-butane tetracarboxylic acid inokufunyanwa, eyimpahla eluhlaza yokwenza iipeyinti ezinyibilikayo emanzini. Ngokufanayo, xa i-anhydride ye-tetrahydrophthalic i-hydrogenated ukuze ifumane i-anhydride ye-hexahydrophthalic, inokusetyenziswa njenge-agent yokunyanga ii-resin ze-epoxy. (3) Iphendula ne-sulfur dioxide ukuze yenze i-sulfolene, ize emva koko yenziwe ibe yisisombululo samanzi kwaye i-hydrogenated xa kukho i-skeletal nickel catalyst ukuze ivelise i-sulfolane, eyisinyibilikisi esikhethiweyo sokukhupha i-hydrocarbon enuka kamnandi. Umxube we-sulfolane kunye ne-diisopropanolamine ungasetyenziselwa ukususa igesi ye-carbon dioxide. (4) I-linear telomerization reaction ye-butadiene isetyenziswa kakhulu kwimizi-mveliso. Emva kwe-linear dimerization, kufunyanwa i-olefin ye-carbon straight-chain esibhozo, kwaye emva kwe-aldehydration kunye ne-hydrogenation, kufunyanwa i-nonanol, enezicelo ezibalulekileyo ekuhlanganiseni iziqholo zokwenziwa, ii-surfactants, kunye nezongezo ze-lubricant. Isebenzisa i-cobalt complex njenge-catalyst, i-dimer, i-trimer, kunye ne-tetramer zonke zizinto eziluhlaza zokwenziwa kwee-alcohols eziphezulu kunye ne-macrocyclic musks. Inyibilika kwi-alcohols kunye ne-ethers, kwaye inokunyibilika kwi-acetone, i-benzene, i-dichloroethane, i-amyl acetate, i-furfural, kunye nesisombululo se-cuprammonium acetate. Ayinyibiliki emanzini.
