1,4-Butanediol waxa uu ka soo jeedaa butane by meelaynta kooxaha khamriga dhamaadka kasta ee silsiladeeda kelli ah iyo waa mid ka mid ah afar isomers xasilloon ee butanediol.the hydroxyl koox kasta dhamaadka ah ee Butanediol falcelin la mono-iyo reagents kala duwan: tusaale ahaan asiidhyada dicarboxylic ilaa polyester-ka, oo leh diisocyanates ilaa polyurethane, ama fosgene ilaa polycarbonates.1.4-Butanediol waa dhexdhexaad tayo sare leh.BDO iyo waxyaabaha ka soo baxa ayaa si weyn loogu isticmaalaa soo saarista balaastikada, dareerayaasha, kiimikooyinka elektarooniga ah iyo fiilooyinka laastikada.Intaa waxaa dheer BDO sidoo kale waa dhisme dhisme oo loogu talagalay isku-darka polyesterpolyols iyo polyetherpolyols.
Butanediol iyo ka-soo-saarkeeda waxaa loo adeegsadaa codsiyo kala duwan oo ka mid ah warshadaha kiimikada;oo ay ku jiraan kuwa kale ee soo saarista balaastikada farsamada, polyurethane, dareerayaasha, kiimikooyinka elektarooniga ah iyo fiilooyinka laastikada.
1,4-Butanediol waxaa loo isticmaalaa isku-darka epothilones, nooc cusub oo dawooyinka kansarka ah.Waxa kale oo loo istcimaalay stereoselective synthesis of (-)-Brevisamide.
1,4-Butanediol adeegsigiisa ugu weyn wuxuu ku dhex jiraa wax soo saarka tetrahydrofuran (THF), oo loo isticmaalo in lagu sameeyo polytetramethylene ether glycol, kaas oo inta badan gala fiilooyinka spandex, elastomer urethane, iyo ethers copolyester.
1,4-Butanediol waxaa caadi ahaan loo isticmaalaa sida dareeraha warshadaha kiimikada si loo soo saaro gamma-butyrolactone iyo fiilooyinka laastikada sida spandex.
Waxa loo istcimaalaa sidii wakiilka iskutallaabta ee kaadimareenka heerkulbeegga, balaastikada polyesterka, rinjiyada iyo dahaarka.
1,4-Butanediol waxay ku dhacdaa fuuq-baxa joogitaanka fosfooraska fosfooraska waxay keentay teterahydrofuran, taas oo ah dareere muhiim ah oo loo isticmaalo codsiyada kala duwan.
1,4-Butanediol wuxuu u shaqeeyaa dhexdhexaad waxaana loo isticmaalaa in lagu soo saaro polytetramethylene ether glycol (PTMEG), polybutylene terephthalate (PBT) iyo polyurethane (PU).
1,4-Butanediol waxay u heshaa codsiga sida nadiifiyaha warshadaha iyo koollada.
1,4-Butanediol sidoo kale waxaa loo isticmaalaa sidii balaastiig ahaan (tusaale ahaan polyester-ka iyo cellulosics), sida dareeraha xambaara ee khad daabacaadda, wakiilka nadiifinta, koollada (maqaarka, balaastikada, laminates polyester iyo kabaha polyurethane), beeraha iyo caafimaadka xoolaha. kiimikooyinka iyo dahaarka (Rinjiyada, varnishes iyo filimada).
Falcelinta Hawada & Biyaha Aad u guban karta.1,4-Butanediol waa hygroscopic.Biyo milmaya.
Profile Reactivity 1,4-Butanediol waa kulayl iyo iftiin xasaasi ah.1,4-Butanediol waxay la falgashaa chlorides acid, anhydrides acid iyo chloroformates;waxay ka falcelisaa walxaha oksaydhaynta iyo yaraynta wakiilada.1,4-Butanediol kuma habboona isocyanates iyo acids;sidoo kale aan la socon karin peroxides, perchloric acid, sulfuric acid, hypochlorous acid, nitric acid, caustics, acetaldehyde, nitrogen peroxide iyo chlorine.
Khatarta sunta ah ee la nuugo.
Khatarta Caafimaadka Saamaynta sunta degdega ah waa mid fudud.1,4-Butanediolis sun yar marka loo eego analooggeeda aan saturate,butenediol iyo butynediol.Qiimaha oralLD50 ee jiirka cad iyo guinea pigsis ~2 mL/kg.Calaamadaha sunta ah ee ka-soo-noqoshada waxaa ka mid noqon kara farxad, niyad-jabka habka dhexe ee neerfayaasha, lallabbo, iyo hurdo.
Khatarta Caafimaadka Cunista xaddi badan oo loo baahan yahay si loo soo saaro calaamad kasta.
Khatarta Dabka Dareeraha aan guban karin, barta iftiimaya (koob furan) 121 ℃.
Xogta Badbaadada Sunta bini'aadamka ee waddo aan la cayimin.Sumaynta dhexdhexaadka ah ee sunta ah iyo dariiqyada intraperitoneal.Saamaynta nidaamka bini'aadamka: wakhtiga hurdada oo la beddelo.Gubi kara marka uu la kulmo kulaylka ama ololka.Si loola dagaallamo dabka, isticmaal xumbo alkohol, ceeryaamo, xumbo, CO2, kiimiko qalalan.Aan ku habboonayn walxaha oksaydhaynta.Marka loo kululeeyo si uu u burburo waxay soo daysaa qaac iyo qiiq.
