1,4-Butanediol (BDO) (CAS: 110-63-4) ndi mankhwala ofunikira a organic ndi zinthu zabwino zopangira mankhwala, apamwamba kwambiri apakati.Ndikupanga Polybutylene Terephthalate (PBT) mapulasitiki opangira uinjiniya ndi ulusi wa PBT, ndipo pulasitiki ya PBT ndi imodzi mwamapulasitiki akuluakulu asanu odalirika.1,4-Butanediol imagwiritsidwa ntchito m'mafakitale monga zosungunulira komanso popanga mitundu ina ya mapulasitiki, zotanuka ulusi ndi polyurethanes.
1,4-Butanediol imachokera ku butane mwa kuika magulu a mowa kumapeto kwa unyolo wa maselo ake ndipo ndi imodzi mwa ma isomers anayi okhazikika a butanediol.the hydroxyl ya gulu lililonse lakumapeto la Butanediol limachita ndi ma reagents osiyanasiyana a mono- ndi bifunctional: mwachitsanzo ndi ma dicarboxylic acid kupita ku ma polyesters, okhala ndi diisocyanates kupita ku polyurethanes, kapena ndi phosgene kupita ku polycarbonates.1.4-Butanediol ndi wapakatikati wapamwamba kwambiri.BDO ndi zotumphukira zake zimagwiritsidwa ntchito kwambiri popanga mapulasitiki, zosungunulira, mankhwala apakompyuta ndi ulusi wotanuka.Kuphatikiza apo, BDO ndi chomangira cha kaphatikizidwe ka polyesterpolyols ndi polyetherpolyols.
Butanediol ndi zotumphukira zake zimagwiritsidwa ntchito mosiyanasiyana pamakampani opanga mankhwala;mwa zina popanga mapulasitiki aukadaulo, ma polyurethanes, zosungunulira, mankhwala apakompyuta ndi ulusi wotanuka.
1,4-Butanediol imagwiritsidwa ntchito popanga epothilones, kalasi yatsopano ya mankhwala a khansa.Amagwiritsidwanso ntchito popanga stereoselective synthesis ya (-) -Brevisamide.
1,4-Butanediol ntchito yaikulu kwambiri ili mkati mwa tetrahydrofuran (THF) kupanga, yomwe imagwiritsidwa ntchito popanga polytetramethylene ether glycol, yomwe imalowa makamaka muzitsulo za spandex, urethane elastomers, ndi copolyester ethers.
1,4-Butanediol imagwiritsidwa ntchito ngati zosungunulira m'makampani opanga mankhwala kupanga gamma-butyrolactone ndi ulusi wotanuka ngati spandex.
Amagwiritsidwa ntchito ngati njira yolumikizirana ndi thermoplastic urethanes, polyester plasticizers, utoto ndi zokutira.
1,4-Butanediol imataya madzi m'thupi pamaso pa phosphoric acid yomwe imatulutsa teterahydrofuran, yomwe ndi yosungunulira yofunikira yomwe imagwiritsidwa ntchito pazinthu zosiyanasiyana.
1,4-Butanediol imagwira ntchito yapakatikati ndipo imagwiritsidwa ntchito popanga polytetramethylene ether glycol (PTMEG), polybutylene terephthalate (PBT) ndi polyurethane (PU).
1,4-Butanediol imapeza ntchito ngati chotsukira mafakitale komanso chochotsa guluu.
1,4-Butanediol imagwiritsidwanso ntchito ngati pulasitiki (mwachitsanzo mu polyester ndi cellulosics), monga chonyamulira chonyamulira mu inki yosindikizira, chotsukira, zomatira (mu zikopa, mapulasitiki, polyester laminates ndi polyurethane nsapato), mu ulimi ndi Chowona Zanyama. mankhwala ndi zokutira (mu utoto, ma varnish ndi mafilimu).
Zochita za Air & Madzi Zoyaka kwambiri.1,4-Butanediol ndi hygroscopic.Madzi sungunuka.
Reactivity Profile 1,4-Butanediol ndi kutentha komanso kuwala.1,4-Butanediol imakhudzidwa ndi asidi chlorides, acid anhydrides ndi chloroformates;imakhudzidwa ndi okosijeni ndi othandizira.1,4-Butanediol sagwirizana ndi isocyanates ndi asidi;Komanso sizigwirizana ndi peroxides, perchloric acid, sulfuric acid, hypochlorous acid, nitric acid, caustics, acetaldehyde, nitrogen peroxide ndi chlorine.
Hazard Toxic pomeza.
Ngozi Yaumoyo Zotsatira zake zoyipa ndizochepa.1,4-Butanediolis wocheperapo poizoni kuposa ma analogi ake unsaturate,butenediol ndi butynediol.Mtengo wa oralLD50 mu makoswe oyera ndi Guinea pigsis ~ 2 mL/kg.Zizindikiro zapoizoni za kumeza zingaphatikizepo chisangalalo, kukhumudwa kwa dongosolo lamanjenje, nseru, ndi kugona.
Ngozi Yaumoyo Kumeza zochulukirapo zofunikira kuti ziwonetsere zizindikiro zilizonse.
Moto Wowopsa wamadzimadzi osayaka, malo owunikira (chikho chotseguka) 121 ℃.
Mbiri Yachitetezo Chiphe chamunthu kudzera m'njira yosadziwika.Kulowetsedwa kwapoizoni pang'ono ndi njira za intraperitoneal.Zotsatira za machitidwe aumunthu: nthawi yosintha yogona.Imatha kuyaka ikayatsidwa ndi kutentha kapena moto.Pofuna kuthana ndi moto, gwiritsani ntchito thovu la mowa, nkhungu, thovu, CO2, mankhwala owuma.Zosagwirizana ndi oxidizing zipangizo.Ikatenthedwa kuti iwonongeke, imatulutsa utsi wobiriwira komanso utsi.
