1,3-Butadiene / CAS 106-99-0

Tšebeliso

E sebelisoa e le thepa e tala bakeng sa rabara ea maiketsetso, resin ea maiketsetso, faeba ea maiketsetso, plasticizer, pente ea latex, jj. Butadiene ke thepa e ka sehloohong e tala bakeng sa tlhahiso ea liraba tsa maiketsetso (rabara ea styrene-butadiene, rabara ea cis-polybutadiene, rabara ea nitrile-butadiene, rabara ea chloroprene). Ka nts'etsopele ea polasetiki ea styrene, ka ho kopanya styrene le butadiene, li-resin tse fapaneng tse nang le ts'ebeliso e pharaletseng (joalo ka resin ea ABS, resin ea SBS, resin ea BS, resin ea MBS) lia hlahisoa, e leng se etsang hore butadiene butle-butle e nke boemo ba bohlokoa tlhahisong ea resin. Ho phaella moo, butadiene e boetse e sebelisoa tlhahisong ea ethylidene norbornene (monomer ea boraro ea rabara ea ethylene-propylene), 1,4-butanediol (polasetiki ea boenjiniere), adiponitrile (monomer ea nylon 66), sulfolane, anthraquinone, tetrahydrofuran, jj. Ka hona, hape ke thepa ea bohlokoa ea mantlha ea lik'hemik'hale. Butadiene e boetse e na le lits'ebetso tse ngata tlhahisong ea lik'hemik'hale tse ntle. Lik'hemik'hale tse ntle tse lokisitsoeng ho sebelisoa butadiene e le thepa e tala li kenyelletsa haholo-holo lintlha tse latelang: (1) E feta karabelong ea Diels-Alder ka metsoako ea dieneophile e haelloang ke li-electron ho hlahisa anthraquinone, 'me lintho tse tsoang ho eona ke metsoako ea bohlokoa ea dae, li-fungicide le likokoanyana tse bolaeang likokoanyana. (2) E arabela le maleic anhydride (e khutsufalitsoeng e le maleic anhydride) ebe ea kopana ho hlahisa tetrahydrophthalic anhydride, e ka sebelisoang e le moemeli oa ho phekola le plasticizer bakeng sa li-resin tsa polyester le li-resin tsa epoxy. Ha tetrahydrophthalic anhydride e ntse e oxidized ka nitric acid, butane tetracarboxylic acid e ka fumanoa, e leng thepa e tala bakeng sa ho etsa pente e qhibilihang metsing. Ka mokhoa o ts'oanang, ha tetrahydrophthalic anhydride e hydrogenated ho fumana hexahydrophthalic anhydride, e ka sebelisoa e le moemeli oa ho phekola bakeng sa li-resin tsa epoxy. (3) E arabela le sulfur dioxide ho etsa sulfolene, ebe e etsoa tharollo e metsi mme e hydrogenated ha ho na le skeletal nickel catalyst ho hlahisa sulfolane, e leng solvent e kgethang bakeng sa ho ntsha hydrocarbon e nkhang hamonate. Motswako wa sulfolane le diisopropanolamine o ka sebediswa bakeng sa ho tlosa khase ya carbon dioxide. (4) Karabelo ya telomerization ya linear ya butadiene e sebediswa haholo indastering. Kamora dimerization ya linear, ho fumanwa olefin ya ketane e otlolohileng ya carbon e robedi, mme kamora aldehydration le hydrogenation, ho fumanwa nonanol, e nang le ditshebediso tsa bohlokwa ho kopanyeng dinkgisamonate tsa maiketsetso, di-surfactants le di-lubricant additives. Ha ho sebediswa cobalt complex e le catalyst, dimer, trimer, le tetramer ya yona kaofela ke thepa e tala bakeng sa ho kopanya di-alcohols tse hodimo le macrocyclic musks. E qhibiliha ka hara alcohols le ethers, mme e ka boela ya qhibilihiswa ka hara acetone, benzene, dichloroethane, amyl acetate, furfural, le cuprammonium acetate solution. Ha e qhibilihe ka metsing.
