Whakamahinga
Ka whakamahia hei rauemi mata mō te rapa hangai, te kapia hangai, te muka hangai, te plasticizer, te peita latex, me ētahi atu. Ko te butadiene te rauemi mata matua mō te hanga rapa hangai (rapa styrene-butadiene, rapa cis-polibutadiene, rapa nitrile-butadiene, rapa chloroprene). I te whanaketanga o ngā kirihou styrene, mā te copolymerizing i te styrene me te butadiene, ka puta ngā momo kapia me ngā tono whānui (pēnei i te kapia ABS, te kapia SBS, te kapia BS, te kapia MBS), ka noho haere te butadiene ki tētahi tūranga nui i roto i te hanga kapia. Hei tāpiri, ka whakamahia hoki te butadiene ki te hanga ethylidene norbornene (te tuatoru o ngā monomer o te rapa ethylene-propylene), 1,4-butanediol (kirihou hangarau), adiponitrile (te monomer o te nylon 66), sulfolane, anthraquinone, tetrahydrofuran, me ētahi atu. Nō reira, he rauemi mata matū taketake nui hoki. He maha ngā tono a te butadiene ki te hanga matū pai. Ko ngā matū pai i hangaia mā te whakamahi i te butadiene hei rauemi mata ko ēnei āhuatanga matua: (1) Ka pāngia e te tauhohenga Diels-Alder me ngā matū dieneophile ngoikore-irahiko hei whakaputa anthraquinone, ā, ko ōna hua he takawaenga tae nui, he patu harore, me he patu pepeke. (2) Ka tauhohe ki te maleic anhydride (whakarāpopototanga ko te maleic anhydride) kātahi ka whakapūmau hei whakaputa tetrahydrophthalic anhydride, ka taea te whakamahi hei rongoā me te plasticizer mō ngā kapia polyester me ngā kapia epoxy. Ina whakahāngaihia anō te tetrahydrophthalic anhydride e te waikawa hauota, ka taea te whiwhi waikawa butane tetracarboxylic, he rauemi mata mō te hanga peita wairewa-wai. Waihoki, ina whakahāngaihia te tetrahydrophthalic anhydride hei whiwhi hexahydrophthalic anhydride, ka taea te whakamahi hei rongoā mō ngā kapia epoxy. (3) Ka tauhohe ki te hauhā whanariki hei hanga i te sulfolene, kātahi ka hangaia hei wairewa wai, ka whakahauwaitia i te aroaro o te whakakorikori nikara angaanga hei hanga sulfolane, he whakarewa whiriwhiri mō te tango hauwai kakara. Ka taea te whakamahi i te ranunga o te sulfolane me te diisopropanolamine hei tango i te hau hauhā waro. (4) He whakamahinga ahumahi nui te tauhohenga telomerization raina o te butadiene. I muri i te dimerization raina, ka whiwhihia he olefin mekameka-tika waru-waro, ā, i muri i te aldehydation me te hydrogenation, ka whiwhihia te nonanol, he tono nui ki te hanga i ngā kakara hangai, ngā surfactants, me ngā tāpiringa hinu. Mā te whakamahi i te matatini cobalt hei whakakorikori, ko tōna dimer, trimer, me te tetramer he rauemi mata katoa mō te hanga i ngā waipiro teitei me ngā musk macrocyclic. Ka wairewa i roto i ngā waipiro me ngā ethers, ā, ka taea hoki te wairewa i roto i te acetone, benzene, dichloroethane, amyl acetate, furfural, me te otinga cuprammonium acetate. Kāore e wairewa i roto i te wai.
