Umenzi wexabiso elilungileyo Tetrahydrofuran CAS:109-99-9

Umenzi Ixabiso Elilungileyo Tetrahydrofuran CAS:109-99-9 Umfanekiso obonakalayo

inkcazelo emfutshane:

I-Tetrahydrofuran (THF) lulwelo olungenambala, oluguquguqukayo olune-ethereal okanye ivumba elifana ne-acetone kwaye liyaxubeka emanzini kunye nezinyibilikisi ezininzi ze-organic.I-Tetrahydrofuran (THF) inokutsha kakhulu kwaye inokubola ngokwe-carbon monoxide kunye ne-carbon dioxide.Ukugcinwa ixesha elide ekudibaneni nomoya kwaye xa kungekho nto yokulwa ne-antioxidant kunokubangela ukuba i-THF ibole ibe yiperoxides eqhumayo.

Ukusetyenziswa kweTetrahydrofuran

I-Tetrahydrofuran isetyenziselwa ukwenziwa kweepolymers kunye nezolimo, amayeza, kunye neekhemikhali zentengiso.Imisebenzi yokuvelisa iqhele ukwenzeka kwiinkqubo ezivaliweyo okanye phantsi kolawulo lobunjineli olunqanda ukuvezwa kwabasebenzi kunye nokukhululwa kokusingqongileyo.I-THF ikwasetyenziswa njengesinyibilikisi (umzekelo, ukufakwa kombhobho) okunokubangela utyhileko olubalulekileyo xa isetyenziswa kwiindawo ezivalelekileyo ngaphandle kokungena komoya okwaneleyo.Nangona i-THF ikhona ngokwendalo kwivumba lekofu, ii-ertyisi eziphekiweyo, kunye nenkukhu ephekiweyo, ukuvezwa kwendalo akulindelwanga ukuba kubangele ingozi enkulu.
I-Butylene oxide isetyenziswa njenge-fumigant kunye nengxubevange kunye nezinye iikhompawundi.Isetyenziselwa ukuzinzisa isibaso malunga nokwakheka kombala kunye nodaka.
I-Tetrahydrofuran isetyenziswe njenge-solvent forresins, i-vinyls, kunye neepolymers eziphezulu;njengeGrignardreaction medium ye-organometallic, kunye ne-metal hydride reactions;kunye nakwi-synthesis ye-succinic acid kunye ne-butyrolactone.
Ukunyibilikisa iipholima eziphezulu, ngakumbi i-polyvinyl chloride.Njengendlela yokusabela kwi-Grignard kunye ne-metal hydride reactions.Kwi-synthesis ye-butyrolactone, i-succinic acid, i-1,4-butanediol diacetate.Ukunyibilika kubuchule be-histological.Isenokusetyenziswa phantsi koMthetho we-Federal Food, Drug & Cosmetic Act ukwenzela ukwenziwa kwamanqaku okupakishwa, ukuthutha, okanye ukugcinwa kokutya ukuba imali eshiyekileyo ayidluli kwi-1.5% yefilimu: Fed.Bhalisa.27, 3919 (Epreli 25, 1962).
I-Tetrahydrofuran isetyenziselwa ikakhulu (i-80%) ukwenza i-polytetramethylene ether glycol, i-polymer esisiseko esetyenziswa ngokuyinhloko ekwenzeni i-elastomeric fibers (umzekelo, i-spandex) kunye ne-polyurethane kunye ne-polyester elastomers (umzekelo, isikhumba sokwenziwa, amavili e-skateboard).Intsalela (20%) isetyenziswa kusetyenziso lwezinyibilikisi (umzekelo, iisamente zemibhobho, izinto zokuncamathelisa, ii-inki zokuprinta, kunye neteyiphu yemagnethi) nanjengento enyibilikayo kwimichiza kunye nokudibanisa amayeza.
