Uruganda Igiciro Cyiza Tetrahydrofuran CAS: 109-99-9

ibisobanuro bigufi:

Tetrahydrofuran (THF) ni amazi adafite ibara, ahindagurika afite impumuro ya ethereal cyangwa acetonelike kandi ntishobora kuboneka mumazi hamwe nudukoko twinshi twinshi.Kubika igihe kirekire uhuye numwuka kandi mugihe hatabayeho antioxydeant birashobora gutuma THF ibora muri peroxide iturika.

Porogaramu ya Tetrahydrofuran

Tetrahydrofuran ikoreshwa mugukora polymers kimwe nubuhinzi, imiti, n’ibicuruzwa.Ibikorwa byo gukora bikunze kugaragara muri sisitemu ifunze cyangwa munsi yubuhanga bugabanya imikoreshereze yabakozi no kurekura ibidukikije.THF nayo ikoreshwa nkigisubizo (urugero, guhuza imiyoboro) bishobora kuvamo ingaruka zikomeye mugihe zikoreshwa ahantu hafunzwe nta guhumeka bihagije.Nubwo THF isanzwe iboneka muri kawa, impumuro yuzuye ifu, hamwe ninkoko zitetse, guhura nibidukikije ntibiteganijwe guteza akaga gakomeye.
Okiside ya Butylene ikoreshwa nka fumigant kandi idahuza nibindi bikoresho.Byakoreshejwe muguhindura lisansi kubijyanye nibara hamwe no gushiraho.
Tetrahydrofuran ikoreshwa nka forresine, vinyls, na polymers ndende;nka Grignardreaction igikoresho cya organometallic, nicyuma hydride reaction;no muri synthesis ya acide succinic na butyrolactone.
Umuti wa polymers muremure, cyane cyane chloride polyvinyl.Nka reaction ya Grignard nicyuma hydride reaction.Muri synthesis ya butyrolactone, acide succinic, 1,4-butanediol diacetate.Gukemura mubuhanga bwamateka.Irashobora gukoreshwa hakurikijwe amategeko agenga ibiryo, ibiyobyabwenge & kwisiga muguhimba ibintu byo gupakira, gutwara, cyangwa kubika ibiryo niba amafaranga asigaye atarenze 1.5% ya firime: Fed.Iyandikishe.27, 3919 (25 Mata 1962).
Tetrahydrofuran ikoreshwa cyane cyane (80%) mu gukora polytetramethylene ether glycol, polymer shingiro ikoreshwa cyane cyane mugukora fibre elastomeric (urugero, spandex) kimwe na polyurethane na elastomers ya polyester (urugero, uruhu rwubukorikori, ibiziga bya skateboard).Ibisigaye (20%) bikoreshwa mubishobora gukoreshwa (urugero, sima ya pompe, ibifatika, wino yo gucapa, hamwe na magnetiki kaseti) kandi nkibisubizo bya reaction muri synthèse chimique na farumasi.
