Umenzi Ixabiso Elihle Tetrahydrofuran CAS:109-99-9

inkcazo emfutshane:

I-Tetrahydrofuran (THF) lulwelo olungenambala, oluguquguqukayo olunevumba elifana nele-ethereal okanye i-acetone kwaye luxutywa emanzini nakwizinyibilikisi ezininzi zezinto eziphilayo. I-Tetrahydrofuran (THF) inokutsha kakhulu kwaye inokubola ngobushushu ibe yi-carbon monoxide kunye ne-carbon dioxide. Ukugcinwa ixesha elide xa udibana nomoya kwaye kungekho antioxidant kunokubangela ukuba i-THF ibole ibe yi-explosive peroxides.

Ukusetyenziswa kweTetrahydrofuran

I-Tetrahydrofuran isetyenziswa ekwenziweni kwee-polymers kunye neekhemikhali zezolimo, amayeza, kunye neemveliso. Imisebenzi yokuvelisa idla ngokwenzeka kwiinkqubo ezivaliweyo okanye phantsi kolawulo lobunjineli oluthintela ukuvezwa kwabasebenzi kunye nokukhululwa kwindalo esingqongileyo. I-THF ikwasetyenziswa njengesinyibilikisi (umz., ukufakwa kwemibhobho) esinokubangela ukuvezwa okukhulu xa kusetyenziswa kwiindawo ezivalekileyo ezingenamoya owaneleyo. Nangona i-THF ikhona ngokwemvelo kwivumba lekofu, iitshizi ezifakwe umgubo, kunye nenkukhu ephekiweyo, ukuvezwa kwendalo akulindelwanga ukuba kube yingozi enkulu.
I-butylene oxide isetyenziswa njengesifunxi-mafutha kwaye ayixutywanga nezinye izinto. Isetyenziselwa ukuzinzisa amafutha ngokubhekiselele kumbala kunye nokwakheka kodaka.
I-Tetrahydrofuran isetyenziswa njengesinyibilikisi se-resins, ii-vinyls, kunye nee-polymers eziphezulu; njengesixhobo se-Grignard reaction kwi-organometallic, kunye ne-metal hydride reactions; nakwi-synthesis ye-succinic acid kunye ne-butyrolactone.
Isinyibilikisi seepolymers eziphezulu, ingakumbi i-polyvinyl chloride. Njengesixhobo sokusabela kwiGrignard kunye neempendulo ze-hydride zesinyithi. Ekuqulunqweni kwe-butyrolactone, i-succinic acid, i-1,4-butanediol diacetate. Isinyibilikisi kwiindlela ze-histological. Singasetyenziswa phantsi koMthetho we-Federal Food, Drug & Cosmetic ekwenzeni izinto zokupakisha, ukuthutha, okanye ukugcina ukutya ukuba inani eliseleyo alidluli kwi-1.5% yefilimu: Fed. Regist. 27, 3919 (Epreli 25, 1962).
I-Tetrahydrofuran isetyenziswa kakhulu (80%) ukwenza i-polytetramethylene ether glycol, i-polymer esisiseko esetyenziswa kakhulu ekwenzeni iifayibha ze-elastomeric (umz., i-spandex) kunye ne-polyurethane kunye ne-polyester elastomers (umz., isikhumba sokwenziwa, amavili e-skateboard). Intsalela (20%) isetyenziswa kwizicelo ze-solvent (umz., ii-cement zepayipi, izincamathelisi, ii-inki zokuprinta, kunye ne-magnetic tape) kwaye njenge-reaction solvent kwi-chemical and pharmaceutical syntheses.
