Ojiji
A na-eji ya eme ihe dị ka ihe e ji emepụta roba sịntetik, resin sịntetik, eriri sịntetik, plasticizer, agba latex, wdg. Butadiene bụ ihe e ji emepụta rọba sịntetik (roba styrene-butadiene, rọba cis-polybutadiene, rọba nitrile-butadiene, rọba chloroprene). Site na mmepe nke plastik styrene, site na ijikọta styrene na butadiene, a na-emepụta resin dị iche iche nwere ọtụtụ ojiji (dị ka resin ABS, resin SBS, resin BS, resin MBS), nke na-eme ka butadiene jiri nwayọọ nwayọọ na-etinye ọnọdụ dị mkpa na mmepụta resin. Na mgbakwunye, a na-ejikwa butadiene eme ihe na mmepụta nke ethylidene norbornene (monomer nke atọ nke rọba ethylene-propylene), 1,4-butanediol (plastic injinia), adiponitrile (monomer nke naịlọn 66), sulfolane, anthraquinone, tetrahydrofuran, na ndị ọzọ. Ya mere, ọ bụkwa ihe dị mkpa dị mkpa maka kemịkalụ dị mkpa. Butadiene nwekwara ọtụtụ ihe eji eme ihe n'imepụta kemịkalụ dị mma. Kemịkalụ dị mma ndị e ji butadiene mee dị ka ihe eji emepụta ihe gụnyere akụkụ ndị a: (1) Ọ na-eme mmeghachi omume Diels-Alder na ngwakọta dieneophile na-enweghị elektrọn iji mepụta anthraquinone, ihe ndị sitere na ya bụkwa ihe dị mkpa maka agba agba, ọgwụ fungicides, na ọgwụ nje. (2) Ọ na-emeghachi omume na maleic anhydride (nke a kpọrọ maleic anhydride) wee gbakọta iji mepụta tetrahydrophthalic anhydride, nke enwere ike iji dị ka ihe na-agwọ ọrịa na plasticizer maka resin polyester na resin epoxy. Mgbe a na-eme ka tetrahydrophthalic anhydride dịkwuo oxidized site na nitric acid, enwere ike nweta butane tetracarboxylic acid, nke bụ ihe eji emepụta agba mmiri na-agbaze. N'otu aka ahụ, mgbe a na-eme ka tetrahydrophthalic anhydride nweta hexahydrophthalic anhydride, enwere ike iji ya dị ka ihe na-agwọ ọrịa maka resin epoxy. (3) Ọ na-emeghachi omume na sulfur dioxide iji mepụta sulfolene, emesịa a na-emepụta ya ka ọ bụrụ mmiri mmiri ma tinye ya na hydrogen n'ihu ihe na-eme ka nickel dị n'ime ya pụta iji mepụta sulfolane, nke bụ ihe na-agbaze maka mwepụta hydrocarbon na-esi ísì ụtọ. Enwere ike iji ngwakọta sulfolane na diisopropanolamine wepụ gas carbon dioxide. (4) Mmeghachi omume telomerization nke butadiene dị oke mma n'ụlọ ọrụ mmepụta ihe. Mgbe linear dimerization gasịrị, a na-enweta olefin carbon-straight-chain asatọ, mgbe aldehydation na hydrogenation gasịrị, a na-enweta nonanol, nke nwere ọrụ dị mkpa na mmepụta nke ihe na-esi ísì ụtọ sịntetik, surfactants, na ihe mgbakwunye mmanụ. Site na iji cobalt complex dị ka ihe na-eme ka ihe na-akpali akpali, dimer, trimer, na tetramer ya niile bụ ihe eji emepụta mmanya dị elu na musk macrocyclic. Ọ na-agbaze na alcohols na ethers, a pụkwara ịgbaze ya na acetone, benzene, dichloroethane, amyl acetate, furfural, na cuprammonium acetate solution. Ọ naghị agbaze na mmiri.
