1,4-Butanediol yog muab los ntawm butane los ntawm kev tso dej cawv pawg ntawm txhua qhov kawg ntawm nws cov saw molecular thiab yog ib qho ntawm plaub lub isomers ruaj khov ntawm butanediol.the hydroxyl muaj nuj nqi ntawm txhua pab pawg kawg ntawm Butanediol reacts nrog sib txawv mono- thiab bifunctional reagents: Piv txwv li nrog dicarboxylic acids rau polyesters, nrog diisocyanates rau polyurethanes, los yog nrog phosgene rau polycarbonates.1.4-Butanediol yog qhov zoo tshaj plaws nruab nrab.BDO thiab nws cov derivatives yog dav siv los tsim cov yas, cov kuab tshuaj, cov tshuaj hluav taws xob thiab cov elastic fibers.Tsis tas li ntawd, BDO tseem yog ib lub tsev thaiv rau kev sib txuas ntawm polyesterpolyols thiab polyetherpolyols.
Butanediol thiab nws cov derivatives yog siv dav hauv kev siv tshuaj lom neeg kev lag luam;ntawm lwm tus hauv kev tsim cov khoom siv yas, polyurethanes, cov kuab tshuaj, cov tshuaj siv hluav taws xob thiab cov elastic fibers.
1,4-Butanediol yog siv rau hauv kev sib txuas ntawm epothilones, chav kawm tshiab ntawm cov tshuaj mob qog noj ntshav.Kuj tseem siv tau rau hauv stereoselective synthesis ntawm (-)-Brevisamide.
1,4-Butanediol kev siv loj tshaj plaws yog nyob rau hauv tetrahydrofuran (THF) ntau lawm, siv los ua polytetramethylene ether glycol, uas feem ntau mus rau hauv spandex fibers, urethane elastomers, thiab copolyester ethers.
1,4-Butanediol feem ntau yog siv los ua cov kuab tshuaj hauv kev lag luam tshuaj los tsim gamma-butyrolactone thiab elastic fibers zoo li spandex.
Nws yog siv los ua tus neeg sawv cev sib txuas rau cov thermoplastic urethanes, polyester plasticizers, xim thiab coatings.
1,4-Butanediol ua rau lub cev qhuav dej nyob rau hauv lub xub ntiag ntawm phosphoric acid yielded teterahydrofuran, uas yog ib qho tseem ceeb hnyav siv rau ntau yam kev siv.
1,4-Butanediol ua ib qho nruab nrab thiab siv los tsim polytetramethylene ether glycol (PTMEG), polybutylene terephthalate (PBT) thiab polyurethane (PU).
1,4-Butanediol pom daim ntawv thov raws li kev siv tshuaj ntxuav thiab cov kua nplaum tshem tawm.
1,4-Butanediol kuj tseem siv los ua plasticiser (xws li hauv polyesters thiab cellulosics), raws li cov khoom hnyav hauv luam ntawv, tus neeg saib xyuas, cov nplaum (hauv tawv, yas, polyester laminates thiab polyurethane khau), hauv kev ua liaj ua teb thiab kws kho tsiaj. chemicals thiab coatings (nyob rau hauv cov xim, varnishes thiab films).
Huab cua & Dej Reactions Highly flammable.1,4-Butanediol yog hygroscopic.Dej soluble.
Reactivity Profile 1,4-Butanediol yog cua sov thiab lub teeb rhiab heev.1,4-Butanediol reacts nrog acid chlorides, acid anhydrides thiab chloroformates;reacts nrog oxidizing agents thiab txo cov neeg ua haujlwm.1,4-Butanediol tsis sib haum nrog isocyanates thiab acids;kuj tsis sib haum nrog peroxides, perchloric acid, sulfuric acid, hypochlorous acid, nitric acid, caustics, acetaldehyde, nitrogen peroxide thiab chlorine.
Hazard Toxic los ntawm kev noj.
Health Hazard Tus mob toxic los yog mob me.1,4-Butanediolis tsis muaj tshuaj lom ntau dua li nws cov tshuaj tsis txaus ntseeg, butenediol thiab butynediol.Tus nqi ntawm qhov ncaujLD50 hauv nas dawb thiab guinea pigsis ~ 2 mL / kg.Cov tsos mob lom los ntawm kev noj haus yuav muaj xws li kev zoo siab, kev nyuaj siab ntawm lub hauv nruab nrab lub paj hlwb, xeev siab, thiab tsaug zog.
Kev Noj Qab Haus Huv Kev Noj Qab Haus Huv Kev Noj Qab Haus Huv ntawm ntau qhov xav tau los tsim cov tsos mob.
Hluav taws kub Hazard Nonflammable kua, flash point (qhib khob) 121 ℃.
Kev Nyab Xeeb Profile Ib tug tib neeg tshuaj lom los ntawm ib txoj kev uas tsis tau teev tseg.Mob ntshav qab zib ntau dhau los ntawm kev noj zaub mov thiab cov kab mob hauv lub cev.Tib neeg cov teebmeem: hloov sijhawm pw tsaug zog.Combustible thaum raug tshav kub los yog nplaim taws.Txhawm rau tua hluav taws, siv cawv ua npuas ncauj, pos huab, ua npuas ncauj, CO2, tshuaj qhuav.Incompatible nrog oxidizing cov ntaub ntawv.Thaum rhuab mus rau decomposition nws emits pa taws thiab fumes.
