Umkhiqizi Intengo Enhle Tetrahydrofuran CAS:109-99-9

Intengo Enhle Yomkhiqizi I-Tetrahydrofuran CAS: 109-99-9 Isithombe Esivelele

incazelo emfushane:

I-Tetrahydrofuran (THF) iwuketshezi olungenambala, oluguquguqukayo olunephunga elifana ne-ethereal noma i-acetone futhi ixubana emanzini kanye nasezithambisweni eziningi eziphilayo. I-Tetrahydrofuran (THF) ivutha kakhulu futhi ingabola ngokushisa ibe yi-carbon monoxide kanye ne-carbon dioxide. Ukugcinwa isikhathi eside uma ixhumene nomoya futhi ingekho i-antioxidant kungabangela i-THF ukuthi ibole ibe yi-peroxide eqhumayo.

Ukusetshenziswa kwe-Tetrahydrofuran

I-Tetrahydrofuran isetshenziswa ekwenziweni kwama-polymer kanye namakhemikhali ezolimo, ezokwelapha, kanye nezimpahla. Imisebenzi yokukhiqiza ivame ukwenzeka ezinhlelweni ezivaliwe noma ngaphansi kokulawulwa kobunjiniyela okunciphisa ukuchayeka kwabasebenzi kanye nokukhululwa emvelweni. I-THF isetshenziswa futhi njengesinyibilikisi (isb., ukufakwa kwamapayipi) esingaholela ekuchayekeni okukhulu uma isetshenziswa ezindaweni ezivalekile ngaphandle komoya owanele. Nakuba i-THF ikhona ngokwemvelo ephunga lekhofi, kuma-chickpeas afakwe ufulawa, kanye nenkukhu ephekiwe, ukuchayeka kwemvelo akulindelekile ukuthi kube yingozi enkulu.
I-butylene oxide isetshenziswa njengesithako sokufutha futhi ayixubeki nezinye izinto ezihlanganisiwe. Isetshenziselwa ukuzinzisa uphethiloli maqondana nombala kanye nokwakheka kodaka.
I-Tetrahydrofuran isetshenziswa njengesixazululo sama-resins, ama-vinyl, nama-polymer aphezulu; njengendlela yokusabela ye-Grignard yokusabela kwe-organometallic, kanye ne-metal hydride; kanye nasekuhlanganisweni kwe-succinic acid kanye ne-butyrolactone.
Isinyibilikisi sama-polymer aphezulu, ikakhulukazi i-polyvinyl chloride. Njengendawo yokusabela ye-Grignard kanye ne-metal hydride reactions. Ekuhlanganisweni kwe-butyrolactone, i-succinic acid, i-1,4-butanediol diacetate. Isinyibilikisi kumasu e-histological. Singasetshenziswa ngaphansi koMthetho Wezokudla, Izidakamizwa kanye Nezimonyo we-Federal Food, Drug & Cosmetic ekwenzeni izinto zokupakisha, ukuthutha, noma ukugcina ukudla uma inani elisele lingadluli ku-1.5% wefilimu: Fed. Regist. 27, 3919 (Ephreli 25, 1962).
I-Tetrahydrofuran isetshenziswa ngokuyinhloko (80%) ukwenza i-polytetramethylene ether glycol, i-polymer eyisisekelo esetshenziswa kakhulu ekwakhiweni kwemicu ye-elastomeric (isb., i-spandex) kanye ne-polyurethane ne-polyester elastomers (isb., isikhumba sokwenziwa, amasondo e-skateboard). Okusele (20%) kusetshenziswa ekusetshenzisweni kwe-solvent (isb., ama-cement amapayipi, izinamathiselo, uyinki wokuphrinta, kanye ne-magnetic tape) kanye ne-reaction solvent ekuhlanganisweni kwamakhemikhali kanye nemithi.
