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

Ukusetshenziswa

Isetshenziswa njengezinto zokusetshenziswa zerabha zokwenziwa, i-resin yokwenziwa, i-fibre yokwenziwa, i-plasticizer, upende we-latex, njll. I-Butadiene iyinto yokusetshenziswa eyinhloko yokwenziwa kwerabha zokwenziwa (irabha ye-styrene-butadiene, irabha ye-cis-polybutadiene, irabha ye-nitrile-butadiene, irabha ye-chloroprene). Ngokuthuthuka kwepulasitiki ye-styrene, ngokuhlanganiswa kwe-styrene ne-butadiene, kukhiqizwa ama-resin ahlukahlukene anezicelo eziningi (njenge-ABS resin, i-SBS resin, i-BS resin, i-MBS resin), okwenza i-butadiene kancane kancane ithathe indawo ebalulekile ekukhiqizweni kwe-resin. Ngaphezu kwalokho, i-butadiene isetshenziswa nasekukhiqizweni kwe-ethylidene norbornene (i-monomer yesithathu yerabha ye-ethylene-propylene), i-1,4-butanediol (ipulasitiki yobunjiniyela), i-adiponitrile (i-monomer ye-nylon 66), i-sulfolane, i-anthraquinone, i-tetrahydrofuran, njalo njalo. Ngakho-ke, futhi iyinto ebalulekile ebalulekile yamakhemikhali. I-Butadiene nayo inezinhlelo eziningi zokusetshenziswa ekukhiqizweni kwamakhemikhali amahle. Amakhemikhali amahle alungiselelwe kusetshenziswa i-butadiene njengento eluhlaza afaka phakathi izici ezilandelayo: (1) Idlula ekusabeleni kwe-Diels-Alder ngamakhemikhali e-dieneophile aswele ama-electron ukuze ikhiqize i-anthraquinone, futhi izinto eziphuma kuyo ziyizinto ezibalulekile zokufaka udayi, ama-fungicides, kanye nemithi yokubulala izinambuzane. (2) Isabela ne-maleic anhydride (efushaniswe ngokuthi i-maleic anhydride) bese iqina ukuze ikhiqize i-tetrahydrophthalic anhydride, engasetshenziswa njenge-ejenti yokwelapha kanye ne-plasticizer yama-polyester resin nama-epoxy resin. Lapho i-tetrahydrophthalic anhydride iqiniswa yi-nitric acid, i-butane tetracarboxylic acid ingatholakala, okuyizinto zokusetshenziswa zokukhiqiza upende oluncibilika emanzini. Ngokufanayo, lapho i-tetrahydrophthalic anhydride ifakwa i-hydrogenated ukuze ithole i-hexahydrophthalic anhydride, ingasetshenziswa njenge-ejenti yokwelapha yama-epoxy resin. (3) Isabela ne-sulfur dioxide ukuze yakhe i-sulfolene, bese ihlanganiswa ibe yisisombululo samanzi bese ifakwa i-hydrogenated lapho kukhona i-skeletal nickel catalyst ukuze ikhiqize i-sulfolane, okuyi-solvent ekhethiwe yokukhipha i-aromatic hydrocarbon. Ingxube ye-sulfolane ne-diisopropanolamine ingasetshenziswa ukususa igesi ye-carbon dioxide. (4) Ukusabela kwe-linear telomerization kwe-butadiene kusetshenziswa kakhulu ezimbonini. Ngemva kwe-linear dimerization, kutholakala i-olefin eqondile ye-carbon eyisishiyagalombili, futhi ngemva kwe-aldehydration ne-hydrogenation, kutholakala i-nonanol, enezicelo ezibalulekile ekwakhiweni kwamakha okwenziwa, ama-surfactants, kanye nezithasiselo zokugcoba. Kusetshenziswa i-cobalt complex njenge-catalyst, i-dimer, i-trimer, kanye ne-tetramer konke kuyizinto zokusetshenziswa zokwenziwa kwama-alcohols aphezulu kanye nama-macrocyclic musks. Iyancibilika kuma-alcohols nama-ethers, futhi ingancibilika naku-acetone, benzene, dichloroethane, amyl acetate, furfural, kanye nesisombululo se-cuprammonium acetate. Ayincibiliki emanzini.
