Umkhiqizi Intengo Enhle I-Tetrahydrofuran CAS:109-99-9

incazelo emfushane:

I-Tetrahydrofuran (THF) iwuketshezi olungenambala, oluguquguqukayo olunephunga le-ethereal noma i-acetone futhi luhlangana emanzini nezinyibilikisi eziningi eziphilayo.I-Tetrahydrofuran (THF) ivutha kakhulu futhi ingase ibole ngokushisa ibe ikhabhoni monoxide nesikhutha.Ukugcina isikhathi eside lapho uthintana nomoya futhi uma ingekho i-antioxidant kungabangela i-THF ukuthi ibole ibe ama-peroxides aqhumayo.

Izicelo Tetrahydrofuran

I-Tetrahydrofuran isetshenziswa ekwenzeni ama-polymers kanye namakhemikhali ezolimo, ezemithi, kanye nempahla.Imisebenzi yokukhiqiza ivamise ukwenzeka kumasistimu avaliwe noma ngaphansi kwezilawuli zobunjiniyela ezikhawulela ukuchayeka kwabasebenzi kanye nokudedela imvelo.I-THF iphinda isetshenziswe njengesinyibilikisi (isb., ukufakwa kwamapayipi) okungase kuphumele ekuchayekeni okubaluleke kakhulu uma isetshenziswa ezindaweni ezivalekile ngaphandle kokungena komoya owanele.Yize i-THF ikhona ngokwemvelo ephunga lekhofi, kuphizi ophekiwe, kanye nenkukhu ephekiwe, ukuchayeka kwemvelo akulindelekile ukuthi kudale ingozi enkulu.
I-Butylene oxide isetshenziswa njenge-fumigant futhi ingaxubeki nezinye izinhlanganisela.Isetshenziselwa ukuzinzisa uphethiloli maqondana nokwakheka kombala nodaka.
I-Tetrahydrofuran isetshenziswa njenge-solvent forresins, ama-vinyls, nama-polymers aphezulu;njenge-Grignardreaction medium ye-organometallic, kanye ne-metal hydride reactions;kanye ne-synthesis ye-succinic acid ne-butyrolactone.
I-solvent yama-polymers aphezulu, ikakhulukazi i-polyvinyl chloride.Njengendlela yokusabela ye-Grignard nokusabela kwe-metal hydride.Ekuhlanganisweni kwe-butyrolactone, i-succinic acid, i-1,4-butanediol diacetate.I-solvent kumasu we-histological.Ingasetshenziswa ngaphansi kwe-Federal Food, Drug & Cosmetic Act ekwenzeni izindatshana zokupakishwa, ukuthuthwa, noma ukugcinwa kokudla uma inani eliyinsalela lingeqi u-1.5% wefilimu: Fed.Bhalisa.27, 3919 (Apr. 25, 1962).
I-Tetrahydrofuran isetshenziswa ngokuyinhloko (80%) ukwenza i-polytetramethylene ether glycol, i-polymer eyisisekelo esetshenziswa ngokuyinhloko ekwenzeni imicu ye-elastomeric (isb, i-spandex) kanye ne-polyurethane ne-polyester elastomers (isb, isikhumba sokwenziwa, amasondo e-skateboard).Okusele (20%) kusetshenziselwa izinto ezincibilikisayo (isb., usimende wamapayipi, izinto zokunamathisela, oyinki bokuphrinta, netheyiphu kazibuthe) nanjengento encibilikayo ekuhlanganiseni kwamakhemikhali nakwezemithi.
