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

Kagwiritsidwe Ntchito

Amagwiritsidwa ntchito ngati zinthu zopangira mphira wopangidwa, utomoni wopangidwa, ulusi wopangidwa, pulasitiki, utoto wa latex, ndi zina zotero. Butadiene ndiye chinthu chachikulu chopangira mphira wopangidwa (mphira wa styrene-butadiene, mphira wa cis-polybutadiene, mphira wa nitrile-butadiene, mphira wa chloroprene). Pakukula kwa mapulasitiki a styrene, pogwiritsa ntchito copolymerizing styrene ndi butadiene, ma resin osiyanasiyana omwe amagwiritsidwa ntchito kwambiri (monga ABS resin, SBS resin, BS resin, MBS resin) amapangidwa, zomwe zimapangitsa butadiene kukhala ndi udindo wofunikira pakupanga utomoni. Kuphatikiza apo, butadiene imagwiritsidwanso ntchito popanga ethylidene norbornene (monomer yachitatu ya ethylene-propylene rabara), 1,4-butanediol (pulasitiki yopangira), adiponitrile (monomer ya nayiloni 66), sulfolane, anthraquinone, tetrahydrofuran, ndi zina zotero. Chifukwa chake, ndi chinthu chofunikira kwambiri cha mankhwala. Butadiene imagwiranso ntchito zambiri popanga mankhwala abwino. Mankhwala abwino omwe amapangidwa pogwiritsa ntchito butadiene ngati chinthu chopangira zinthu makamaka amakhala ndi zinthu izi: (1) Imadutsa mu Diels-Alder reaction ndi mankhwala a dieneophile osowa ma electron kuti apange anthraquinone, ndipo zotumphukira zake ndi zinthu zofunika kwambiri zopaka utoto, fungicides, ndi tizilombo toyambitsa matenda. (2) Imayanjana ndi maleic anhydride (yofupikitsidwa ngati maleic anhydride) kenako imaundana kuti ipange tetrahydrophthalic anhydride, yomwe ingagwiritsidwe ntchito ngati chochiritsira komanso pulasitiki ya ma polyester resins ndi ma epoxy resins. Pamene tetrahydrophthalic anhydride ikawonjezedwanso ndi nitric acid, butane tetracarboxylic acid ingapezeke, yomwe ndi chinthu chopangira utoto wosungunuka m'madzi. Mofananamo, pamene tetrahydrophthalic anhydride imayikidwa hydrogenated kuti ipange hexahydrophthalic anhydride, ingagwiritsidwe ntchito ngati chochiritsira ma epoxy resins. (3) Imakumana ndi sulfure dioxide kuti ipange sulfolene, kenako imapangidwa kukhala yankho lamadzi ndikulowetsedwa ndi hydrogen pamaso pa chothandizira cha nickel cha mafupa kuti ipange sulfolane, yomwe ndi chosungunulira chosankha cha kutulutsa hydrocarbon. Chisakanizo cha sulfolane ndi diisopropanolamine chingagwiritsidwe ntchito pochotsa mpweya wa carbon dioxide. (4) Njira yolumikizira ya butadiene imagwiritsidwa ntchito kwambiri m'mafakitale. Pambuyo pa dimerization yolunjika, olefin yolunjika ya kaboni eyiti imapezedwa, ndipo pambuyo pa aldehyde ndi hydrogenation, nonanol imapezedwa, yomwe imagwiritsidwa ntchito kwambiri popanga zonunkhira zopangidwa, ma surfactants, ndi zowonjezera mafuta. Pogwiritsa ntchito cobalt complex ngati chothandizira, dimer, trimer, ndi tetramer zake zonse ndi zinthu zopangira ma alcohols apamwamba ndi macrocyclic musks. Imasungunuka mu alcohols ndi ethers, ndipo imathanso kusungunuka mu acetone, benzene, dichloroethane, amyl acetate, furfural, ndi cuprammonium acetate solution. Sisungunuka m'madzi.

Kulongedza ndi Kutumiza

monga zofunikira kwa makasitomala.
Ndi katundu wamba ndipo amatha kutumizidwa kudzera m'nyanja ndi mlengalenga

Sungani ndi kusunga

Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
