Wopanga Mtengo Wabwino Tetrahydrofuran CAS:109-99-9

Kufotokozera mwachidule:

Tetrahydrofuran (THF) ndi madzi opanda mtundu, osasunthika okhala ndi fungo la ethereal kapena acetone ndipo amasakanikirana m'madzi ndi zosungunulira zambiri za organic.Kusungidwa kwanthawi yayitali pakukhudzana ndi mpweya komanso ngati palibe antioxidant kungayambitse THF kuwola kukhala ma peroxides ophulika.

Kugwiritsa ntchito Tetrahydrofuran

Tetrahydrofuran imagwiritsidwa ntchito popanga ma polima komanso mankhwala aulimi, mankhwala, komanso mankhwala.Ntchito zopanga zinthu nthawi zambiri zimachitika m'makina otsekedwa kapena pansi paulamuliro wa uinjiniya womwe umachepetsa kuwonekera kwa ogwira ntchito ndikumasulidwa ku chilengedwe.THF imagwiritsidwanso ntchito ngati zosungunulira (mwachitsanzo, kuyika chitoliro) zomwe zingapangitse kuti pakhale zowonekera kwambiri zikagwiritsidwa ntchito m'malo otsekeka popanda mpweya wokwanira.Ngakhale THF imapezeka mwachilengedwe mufungo la khofi, napiye wothira ufa, ndi nkhuku yophika, mawonekedwe achilengedwe sakuyembekezeka kubweretsa ngozi yayikulu.
Butylene oxide imagwiritsidwa ntchito ngati fumigant komanso kusakanikirana ndi mankhwala ena.Amagwiritsidwa ntchito kuti akhazikitse mafuta pokhudzana ndi mapangidwe amtundu ndi matope.
Tetrahydrofuran imagwiritsidwa ntchito ngati zosungunulira za forresins, vinyls, ndi ma polima apamwamba;monga Grignardreaction sing'anga kwa organometallic, ndi zitsulo hydride zochita;komanso mu kaphatikizidwe ka succinic acid ndi butyrolactone.
Zosungunulira za ma polima apamwamba, makamaka polyvinyl chloride.Monga reaction sing'anga ya Grignard ndi metal hydride reactions.Mu synthesis ya butyrolactone, succinic acid, 1,4-butanediol diacetate.Zosungunulira mu histological njira.Itha kugwiritsidwa ntchito pansi pa Federal Food, Drug & Cosmetic Act popanga zolemba pakuyika, kunyamula, kapena kusunga zakudya ngati zotsalira sizikupitilira 1.5% yafilimuyo: Fed.Lembani.27, 3919 (Apr. 25, 1962).
Tetrahydrofuran imagwiritsidwa ntchito makamaka (80%) kupanga polytetramethylene etha glycol, polima m'munsi ntchito makamaka kupanga elastomeric ulusi (mwachitsanzo, spandex) komanso polyurethane ndi poliyesitala elastomers (mwachitsanzo, chikopa yokumba, mawilo skateboard).Zotsalira (20%) zimagwiritsidwa ntchito posungunulira (mwachitsanzo, simenti za chitoliro, zomatira, inki zosindikizira, ndi tepi ya maginito) komanso monga zosungunulira mu mankhwala ndi mankhwala.
