Mtengo Wabwino Wopanga Tetrahydrofuran CAS:109-99-9

kufotokozera mwachidule:

Tetrahydrofuran (THF) ndi madzi opanda mtundu, osasunthika okhala ndi fungo lofanana ndi la ethereal kapena acetone ndipo amatha kusakanikirana m'madzi ndi zinthu zambiri zachilengedwe. Tetrahydrofuran (THF) imatha kuyaka kwambiri ndipo imatha kuwola kutentha kukhala carbon monoxide ndi carbon dioxide. Kusungidwa kwa nthawi yayitali pokhudzana ndi mpweya komanso popanda antioxidant kungayambitse THF kuwola kukhala ma peroxide ophulika.

Kugwiritsa ntchito Tetrahydrofuran

Tetrahydrofuran imagwiritsidwa ntchito popanga ma polima komanso mankhwala a zaulimi, mankhwala, ndi zinthu zina. Ntchito zopangira nthawi zambiri zimachitika m'makina otsekedwa kapena pansi pa maulamuliro aukadaulo omwe amachepetsa kukhudzana ndi kutulutsidwa kwa ogwira ntchito ku chilengedwe. THF imagwiritsidwanso ntchito ngati chosungunulira (monga, kuyika mapaipi) chomwe chingayambitse kukhudzana kwakukulu ngati chikugwiritsidwa ntchito m'malo otsekedwa opanda mpweya wokwanira. Ngakhale kuti THF imapezeka mwachilengedwe mu fungo la khofi, nsawawa zophikidwa, ndi nkhuku yophikidwa, kukhudzana ndi chilengedwe sikuyembekezeredwa kuti kungayambitse ngozi yayikulu.
Butylene oxide imagwiritsidwa ntchito ngati mankhwala ophera fumbi komanso osasakanikirana ndi mankhwala ena. Imagwiritsidwa ntchito kukhazikika kwa mafuta poyerekeza ndi mtundu ndi matope.
Tetrahydrofuran imagwiritsidwa ntchito ngati chosungunulira ma resini, ma vinyl, ndi ma polima ambiri; ngati njira yochitira Grignard ya organometallic, ndi metal hydride reactions; komanso popanga succinic acid ndi butyrolactone.
Chosungunulira cha ma polima ambiri, makamaka polyvinyl chloride. Monga njira yochitira zinthu pa Grignard ndi metal hydride reactions. Pakupanga butyrolactone, succinic acid, 1,4-butanediol diacetate. Chosungunulira mu njira za histological. Chingagwiritsidwe ntchito motsatira Federal Food, Drug & Cosmetic Act popanga zinthu zolongedza, kunyamula, kapena kusungira zakudya ngati kuchuluka kotsala sikupitirira 1.5% ya filimuyi: Fed. Regist. 27, 3919 (Epulo 25, 1962).
Tetrahydrofuran imagwiritsidwa ntchito makamaka (80%) popanga polytetramethylene ether glycol, polima yoyambira yomwe imagwiritsidwa ntchito makamaka popanga ulusi wa elastomeric (monga spandex) komanso polyurethane ndi polyester elastomers (monga chikopa chopangira, mawilo a skateboard). Yotsalayo (20%) imagwiritsidwa ntchito popanga zosungunulira (monga simenti za mapaipi, zomatira, inki zosindikizira, ndi tepi yamaginito) komanso ngati zosungunulira zomwe zimagwiritsidwa ntchito popanga mankhwala ndi mankhwala.
