Soo-saare Qiimo Fiican Tetrahydrofuran CAS:109-99-9

sharraxaad gaaban:

Tetrahydrofuran (THF) waa dareere aan midab lahayn, oo isbeddelaya oo leh ur ethereal ama acetone u eg, waana la isku dhex milmi karaa biyaha iyo inta badan dareerayaasha dabiiciga ah. Tetrahydrofuran (THF) aad ayuu u guban karaa wuxuuna si kuleyl ah u burburin karaa kaarboon monoxide iyo kaarboon laba ogsaydh. Kaydinta muddada dheer ee la xiriirta hawada iyo maqnaanshaha antioxidant-ka waxay sababi kartaa in THF ay u qudhunto peroxides qarxa.

Isticmaalka Tetrahydrofuran

Tetrahydrofuran waxaa loo isticmaalaa soo saarista polymers iyo sidoo kale kiimikooyinka beeraha, daawooyinka, iyo badeecadaha. Hawlaha wax soo saarka waxay badanaa ka dhacaan nidaamyada xiran ama xakamaynta injineernimada kuwaas oo xaddidaya soo-gaadhista shaqaalaha iyo sii deynta deegaanka. THF waxaa sidoo kale loo isticmaalaa sidii dareere (tusaale ahaan, ku habboonaanta tuubooyinka) taasoo keeni karta soo-gaadhis badan marka loo isticmaalo meelaha xaddidan iyada oo aan lahayn hawo ku filan. Inkasta oo THF si dabiici ah looga helo caraf udgoon kafeega, digirta la shiiday ee burka leh, iyo digaagga la kariyey, soo-gaadhista dabiiciga ah lama filayo inay keento khatar weyn.
Butylene oxide waxaa loo isticmaalaa sidii qiiq-shid iyo isku-darka aan la isku darin walxo kale. Waxaa loo isticmaalaa in lagu xasiliyo shidaalka marka loo eego midabka iyo sameynta dhoobada.
Tetrahydrofuran waxaa loo isticmaalaa sidii dareere u ah resins, vinyls, iyo polymers sare; sida dhexdhexaad falgal Grignard ah oo loogu talagalay falgallada organometallic, iyo bir hydride; iyo isku-darka succinic acid iyo butyrolactone.
Xal u ah polymers-ka sare, gaar ahaan polyvinyl chloride. Sida dhexdhexaad falgal ah oo loogu talagalay falcelinta Grignard iyo biraha hydride. Isku-darka butyrolactone, succinic acid, 1,4-butanediol diacetate. Xal u ah farsamooyinka histological. Waxaa loo isticmaali karaa iyadoo la raacayo Xeerka Cuntada, Daawada & Qurxinta Federaalka si loo sameeyo walxaha loogu talagalay baakadaha, rarista, ama kaydinta cuntooyinka haddii xaddiga harsan uusan ka badnayn 1.5% filimka: Fed. Regist. 27, 3919 (Abriil 25, 1962).
Tetrahydrofuran waxaa ugu horreyn loo isticmaalaa (80%) si loo sameeyo polytetramethylene ether glycol, oo ah polymer-ka saldhigga ah ee loo isticmaalo soo saarista fiilooyinka elastomeric (tusaale ahaan, spandex) iyo sidoo kale polyurethane iyo polyester elastomers (tusaale ahaan, maqaar macmal ah, giraangiraha skateboard-ka). Inta soo hartay (20%) waxaa loo isticmaalaa codsiyada dareeraha (tusaale ahaan, sibidhka tuubooyinka, dhejisyada, khad daabacan, iyo cajalad birlab ah) iyo sidoo kale dareere falcelin ah oo ku jira kiimikada iyo daawooyinka.
