Kushandiswa
Inoshandiswa sechinhu chisina kugadzirwa cherabha rekugadzira, resin rekugadzira, fiber rekugadzira, plasticizer, pendi yelatex, nezvimwewo. Butadiene ndiyo chinhu chikuru chekugadzira rabha rekugadzira (rabha restyrene-butadiene, rabha recis-polybutadiene, rabha renitrile-butadiene, rabha rechloroprene). Nekugadzirwa kwemapurasitiki estyrene, nekugadzira copolymerizing styrene nebutadiene, maresini akasiyana-siyana ane mashandisirwo akasiyana-siyana (akadai seABS resin, SBS resin, BS resin, MBS resin) anogadzirwa, izvo zvinoita kuti butadiene itore nzvimbo yakakosha mukugadzirwa kweresin. Pamusoro pezvo, butadiene inoshandiswawo mukugadzirwa kweethylidene norbornene (monomer yechitatu yerabha re ethylene-propylene), 1,4-butanediol (engineering plastic), adiponitrile (monomer yenylon 66), sulfolane, anthraquinone, tetrahydrofuran, nezvimwewo. Nokudaro, ichinhu chakakosha chemakemikari. Butadiene ine mashandisirwo akawanda mukugadzira makemikari akanaka. Makemikoro akanaka akagadzirwa achishandisa butadiene sechinhu chisina kugadzirwa anosanganisira zvinhu zvinotevera: (1) Inopinda muDiels-Alder reaction nemakemikari e dieneophile asina ma electron kuti igadzire anthraquinone, uye zvinobva mairi zvakakosha pakati pedhayi, fungicides, uye zvipembenene. (2) Inosangana ne maleic anhydride (yakapfupikiswa se maleic anhydride) uye yozobatana kuti igadzire tetrahydrophthalic anhydride, iyo inogona kushandiswa semushonga wekupisa uye plasticizer ye polyester resin uye epoxy resin. Kana tetrahydrophthalic anhydride ikasanganiswa ne nitric acid, butane tetracarboxylic acid inogona kuwanikwa, inova chinhu chisina kugadzirwa chekugadzira pendi inonyunguduka mumvura. Saizvozvowo, kana tetrahydrophthalic anhydride yakasanganiswa ne hydrogen kuti iwane hexahydrophthalic anhydride, inogona kushandiswa semushonga wekupisa epoxy resin. (3) Inosangana nesulfur dioxide kuti igadzire sulfolene, uye yozogadzirwa kuita mhinduro yemvura uye hydrogenated pamberi pe skeletal nickel catalyst kuti igadzire sulfolane, inova solvent yakasarudzwa yekubvisa aromatic hydrocarbon. Musanganiswa wesulfolane ne diisopropanolamine unogona kushandiswa kubvisa carbon dioxide gasi. (4) Kuitwa kwe telomerization kwe butadiene kuri kushandiswa zvikuru mumaindasitiri. Mushure me dimerization ye linear, olefin ye eight-carbon straight-chain inowanikwa, uye mushure me aldehydration ne hydrogenation, nonanol inowanikwa, iyo ine mashandisirwo akakosha mukugadzirwa kwezvinonhuwira zve synthetic, surfactants, uye lubricant additives. Ichishandisa cobalt complex se catalyst, dimer yayo, trimer, uye tetramer zvese zvinhu zvekugadzira higher alcohols uye macrocyclic musks. Inonyungudika mu alcohols ne ethers, uye inogonawo kunyungudika mu acetone, benzene, dichloroethane, amyl acetate, furfural, uye cuprammonium acetate solution. Hainyungudike mumvura.
