Tufuga Tau Lelei Tetrahydrofuran CAS:109-99-9

fa'amatalaga puupuu:

Tetrahydrofuran (THF) o se vai e leai se lanu, fe'avea'i ma le manogi ethereal po'o le acetonelike ma e fa'afefiloi i le vai ma le tele o so'o so'o. Tetrahydrofuran (THF) e matua mu ma e mafai ona pala i le carbon monoxide ma carbon dioxide. O le umi o le teuina i feso'ota'iga ma le ea ma le leai o se antioxidant e ono fa'aoso ai le THF i ni peroxide pa'u.

Fa'aaogāga ole Tetrahydrofuran

Tetrahydrofuran e faʻaaogaina i le gaosiga o polymers faʻapea foʻi ma faʻatoʻaga, vailaʻau, ma vailaʻau faʻatau. O gaioiga gaosi e masani ona tupu i faiga tapuni poʻo lalo ole pulega faʻainisinia e faʻatapulaʻa ai le faʻaalia o tagata faigaluega ma tuʻuina atu i le siosiomaga. O lo'o fa'aaogaina fo'i le THF e fai ma so'o (fa'ata'ita'iga, fa'apipi'i paipa) e ono i'u ai i fa'aaliga sili atu ona taua pe a fa'aoga i nofoaga pupuni e aunoa ma le lava o le ea. E ui lava o le THF o lo'o iai i le manogi kofe, figota falaoamata, ma moa vela, e le'o fa'amoemoeina fa'alenatura e tula'i mai se lamatiaga tele.
O le butylene oxide e faʻaaogaina e avea o se fumigant ma e le faʻafefiloi ma isi mea faʻapipiʻi. E fa'aaogaina e fa'amautu ai le suau'u e tusa ai ma le lanu ma le fa'avaeina o le palapala.
Tetrahydrofuran o loʻo faʻaaogaina e avea o se solvent forresins, vinyls, ma polymers maualuga; e avea o se auala Grignardreaction mo organometallic, ma u'amea hydride tali; ma i le tu'ufa'atasiga ole succinic acid ma le butyrolactone.
Solvent mo polymers maualuga, aemaise lava polyvinyl chloride. E fai ma auala e tali atu ai mo Grignard ma tali u'amea hydride. I le tuufaatasia o le butyrolactone, succinic acid, 1,4-butanediol diacetate. Solvent i le histological techniques. E mafai ona fa'aoga i lalo ole Federal Food, Drug & Cosmetic Act mo le fausiaina o mea mo le afifiina, felauaiga, po'o le teuina o mea'ai pe a le sili atu i le 1.5% le aofa'i o le ata: Fed. Resitala. 27, 3919 (Ape. 25, 1962).
O le Tetrahydrofuran e fa'aaoga muamua (80%) e fai ai le polytetramethylene ether glycol, o le polymer faavae e fa'aaoga muamua i le gaosiga o alava elastomeric (eg, spandex) fa'apea fo'i polyurethane ma polyester elastomers (fa'ata'ita'iga, pa'u fa'akomepiuta, uili laupapa). O le vaega o totoe (20%) o lo'o fa'aogaina i mea e fa'amalie ai (fa'ata'ita'iga, sima paipa, fa'apipi'i, vaitusi lolomi, ma le fa'amau maneta) ma e fai ma so'o fa'afofoga i vaila'au ma vaila'au.
